Description

Language learning devices and methods

This application relates to language learning devices and methods that enable effective learning of languages, including Korean and foreign languages (eg, English, Japanese, French, etc.).

Language is a means of general human communication and can be said to be a very important element in people's lives. Recently, as we enter the global era, the importance of learning languages from various countries, including English, has been emphasized, and efforts are being made to easily learn the languages of various countries in line with the trend of the times.

In general, when learning languages such as Korean or foreign languages (e.g. English, Japanese, etc.), people tend to focus on memorizing words. However, the learning method of simply memorizing words has limitations in improving the ability to interpret and understand given sentences, problems, etc. or the ability to write sentences.

Additionally, students learning a foreign language usually purchase a vocabulary book and plan to memorize a few words each day, but they tend to memorize only new words each day, skipping the process of reviewing the words they memorized the previous day. However, in the case of human memory, the memory tends to be forgotten as time passes, so this learning method (i.e., memorizing new words every day without reviewing the words memorized the previous day) , there is a problem that when you look at a previously memorized word again after some time, the word comes across as an unfamiliar and new word and you have to memorize it again.

Therefore, for more effective language learning, it is necessary to develop technology that allows learning on a regular and consistent basis and allows repeated learning (review) when memory fades. However, there is currently no appropriate technology to meet this need. am.

The technology behind this application is disclosed in Korean Patent Publication No. 10-2022-0047485.

A more detailed description of the device 10 is as follows.

2 to 6 are diagrams showing examples of screens provided by the language learning device 10 according to an embodiment of the present application. Here, Figure 4 (i.e., Figures 4a and 4b) shows an example of a process in which today's problem of the 17th day (today's problem of the day) is provided. 7 and 8 are diagrams for explaining the language learning device 10 according to an embodiment of the present application.

1 to 8, the device 10 may include a provision unit 11 and a review control unit 12. In addition, although not shown in the drawing, the device 10 includes a database unit (not shown) that stores a plurality of problems, and various information provided by the device 10 (for example, It may include a display unit (not shown), which is a screen that displays (problems, etc.), and a control unit (not shown) that controls the operation of each unit within the device 10. For example, a control unit (not shown) may control the display of a screen displayed on a display unit (not shown).

The provision unit 11 may provide today's problems for language learning. The providing unit 11 may provide at least one problem among a plurality of problems stored in the database unit (not shown) as today's problem. The providing unit 11 may provide today's problems to be displayed on a display unit (not shown).

Problems considered in the device 10 (i.e., today's problem, review problem, multiple problems stored in a database unit (not shown), etc.) may be problems related to language learning, that is, problems for language learning. At this time, various languages can be considered, including not only Korean but also foreign languages such as English, Japanese, Chinese, and French. In other words, the device 10 may be a language learning device capable of learning various languages (eg, Korean, English, Japanese, Chinese, French, etc.). By way of example, the problem considered in the present device 10 may be a problem related to English writing or listening problems.

Today's problem provided by the providing unit 11 may include a plurality of problems provided at a plurality of times at a preset time. The provision unit 11 provides today's problems every day, and may provide new today's problems every day.

Here, the preset time for multiple times may mean a time corresponding to a different time point of multiple times based on the same day (24 hours a day), and here, multiple times may be three times. For example, the preset times for multiple times include 8 o'clock, which is the first preset time (the first time), 14 o'clock, which is the second preset time (the second time), and the third preset time (the third time). ) may be included at 20 o'clock.

According to this, today's problem is the first problem provided at 8 o'clock (today's first problem), the second problem provided at 14 o'clock (today's second problem), and the third problem provided at 20 o'clock (today's first problem). 3rd problem) may be included. In today's issue here, the first problem is Q1 (Question 1) as the first problem provided, the second problem is Q2 (Question 2) as the second problem provided, and the third problem is Q3 (Question 3) as the third problem provided. It can be expressed as

In explaining the present device 10, the content explained for any one of the plurality of problems (Q1, Q2, Q3) in today's problem is the same as the explanation for each of the plurality of problems even if the content is omitted below. It can be applied easily. In addition, the content explained regarding the Problem of the Day provided on any one of the Problem of the Day provided every day may be equally applied to the explanation of the Problem of the Day provided on other days (every day) even if the content is omitted below. there is.

According to this, the provision unit 11 can provide three problems (Q1, Q2, Q3) as today's problems at a set time every day (i.e., 8:00, 14:00, and 20:00). The provision unit 11 can provide three problems as the Problem of the Day every day, and each of the three problems within the Problem of the Day can be provided one by one at different preset times (8:00, 14:00, and 20:00). there is.

As the provision unit 11 provides a new problem every day as the problem of the day, the problem of the day provided on the next day (the next day) may be a new problem that is different from the problem of the day provided on the same day. In other words, the providing unit 11 can provide a new (new) problem of the day every day without providing the same duplicate problem.

In the above-mentioned example, the preset times for multiple sessions are set to 8:00, 14:00, and 20:00. However, this is only an example to aid understanding of the application, and is not limited to this. The preset times for multiple sessions are set by the user. It can be changed or set to a different value by (the learner).

In other words, the control unit (not shown) can control the user to set a plurality of preset times, which is the time (time) at which each of the plurality of problems (three problems Q1, Q2, and Q3) in today's problem is provided. At this time, when the user sets a plurality of preset times, the control unit (not shown) can control the interval between the plurality of preset times to be set to an interval of at least 3 hours or more, as shown in FIG. 5 .

The control unit (not shown) may display a learning time setting screen as shown in FIG. 5 on the screen of the display unit. Through the learning time setting screen, users can set the time (time) at which each of the multiple problems (Q1, Q2, Q3) in Today's Problem are provided. At this time, the control unit (not shown) can control the time interval between problems to be at least 3 hours or more in order to maximize the effect of unconsciously organizing the brain's memory and prevent 'cramming' learning habits. In other words, when the user performs language learning through the device 10, the control unit (not shown) maximizes the effect of unconsciously organizing the brain's memory and prevents 'cramming' learning habits. The interval between the provision times of multiple problems (3 problems) provided can be controlled to be set to at least 3 hours. In this way, the 'feature that controls the interval setting between the times when multiple problems within the Today's Problem are provided is set to an interval of at least 3 hours or more' can be referred to as the fifth feature of this app as an example.

For example, if the learning time (i.e., the preset time for the first time) of the first problem (Q1), which is the first problem in today's problem, is set to 8 o'clock, the control unit (not shown) The learning time in (Q2) can be controlled to be set to any time after 11 o'clock. That is, since the study time for the first problem (Q1) is 8 o'clock, the study time for the second problem (Q2) can be set to a time after 11 o'clock, which is at least 3 hours later. If the learning time for the second problem is set to 11 o'clock, the control unit (not shown) sets the learning time for the third problem (Q3) at least 3 hours from 11 o'clock (11 o'clock, the learning time for the second problem). It can be controlled to be set to any time after 14:00.

That is, for example, if the study time for the first question (Q1) is 08:00, the study time can be set so that the second question (Q2) can be received at 11:00, at least 3 hours later. The control unit (not shown) can widen the interval of 3 hours according to the user's (learner's) inclination and judgment, but can control it so that the interval cannot be reduced to less than 3 hours. In other words, the control unit (not shown) allows the user to set the interval between the provision times of a plurality of problems (3 problems) provided as the problem of the day to a wider period of time (eg, 5 hours, 6 hours, etc.) based on 3 hours. It can be controlled so that it can be set at intervals, and it can be controlled so that settings cannot be made at intervals narrower than the 3-hour interval (e.g., 1 hour, 2 hours, etc.).

If the preset times for multiple sessions are set to '8:00, 14:00, 20:00', the provider 11 provides today's problem one at 8:00, 14:00, and 20:00 on today's day, for a total of 3. One problem is provided, and the next day, one problem of the day is provided at 8:00, 14:00, and 20:00, for a total of 3 problems.

The review control unit 12 may consider whether the user has completed learning about today's problem provided by the provision unit 11 and provide a review problem for reviewing the completed problem. The review control unit 12 may provide review problems corresponding to completed problems to be displayed on a display unit (not shown) so that review of completed problems is possible. The review problem may be the same problem as the study completion problem.

After one problem (for example, Q1) among a plurality of problems in today's problem is provided by the provision unit 11, the review control unit 12 selects the next problem (i.e., Q2) of one problem (for example, Q1). If it is confirmed that the user has completed learning a problem (eg, Q1) before the provided time, the problem (eg, Q1) may be recognized as a learning complete problem.

On the other hand, after one problem (e.g. Q1) among a plurality of problems in today's problem is provided by the provision unit 11, the review control unit 12 controls the next problem (e.g. Q2) of one problem (e.g. Q1). If it is confirmed that the user has not completed learning a problem (for example, Q1) before the time when ) is provided, a problem (for example, Q1) may be recognized as an uncompleted learning problem. The review control unit 12 may, in the case of an unfinished problem that is confirmed to have not been completed by the user among the plurality of problems in today's problem provided by the providing unit 11, delete it so that re-study and review are not possible. there is.

In particular, when deleting an incomplete study problem, the review control unit 12 deletes a review problem (at least one review problem) previously provided before the incomplete study problem before the incomplete study problem to be deleted is provided as today's problem. ) exists, the incomplete learning problem and the previous review problem (at least one review problem) of the incomplete learning problem can be deleted together. For example, with reference to FIG. 4B, which will be described later, the provision unit 11 provides Q2 today's problem of the 14th day, for example, 'Q2 review problem of the 7th day → Q2 review problem of the 11th day → Q2 review of the 13th day. After providing the ‘problems’ sequentially, you can provide the Q2 problem of the day on the 14th day. At this time, if the user fails to complete learning of the Q2 Today's Problem of the 14th day within the learning validity period and is recognized as an uncompleted problem, the review control unit 12 makes it impossible to re-learn and review the Q2 Today's Problem of the 14th day. You can delete it to do so. Therefore, if the Q2 today's problem of the 14th day was a study completion problem, the review control unit 12 would have provided the Q2 review problem of the 14th day on the 15th and 17th days, respectively, as shown in FIG. 4B. However, if the Q2 today's problem of the 14th day is an incomplete study problem, the review control unit 12 deletes the Q2 today's problem of the 14th day, so that the 14th day Q2 review problem of the 14th day includes the 15th and 17th days. You can make it impossible to re-study or review by not providing it at all after the 14th day. At this time, when the review control unit 12 deletes the Q2 today's problem of the 14th day, the review problems previously provided before the Q2 today's problem of the 14th day (i.e., the Q2 review problem of the 7th day, the Q2 review problem of the 11th day, and Day 13 Q2 review questions) can also be deleted together.

According to this, when one of the plurality of problems in Today's Problem is provided by the providing unit 11, the learning effective time that the user can learn for one provided problem (i.e., the effective time to solve the problem) ) can be set as the time from the time (point in time) at which one problem is provided until (immediately before) the time (point in time) at which the next problem provided after one problem is provided.

That is, the review control unit 12 recognizes a problem for which learning has not been completed within the learning effective time as an incomplete learning problem for each of the plurality of problems (Q1, Q2, Q3) in today's problem, and learns the problem within the learning effective time. This completed problem can be recognized as a learned problem. At this time, the effective learning time for each of the plurality of problems (Q1, Q2, Q3) can be set to the time until (immediately before) the time when the next problem is provided.

As an example, let's say that the time at which multiple problems (Q1, Q2, Q3) in Today's Problem are provided (the preset time for multiple sessions is set to 8:00, 14:00, and 20:00. That is, as today's problem every day, Let's say Q1 is provided at 8 o'clock, Q2 is provided at 14 o'clock, and Q3 is provided at 20 o'clock.

At this time, let's say that the provider 11 provided Q1, the first problem of the day, at 8 o'clock on May 1. The user may be able to learn about the Q1 problem only until 14:00 (i.e., 13:59:59), which is the time when the next problem, Q2 problem, is provided (i.e., the user can only solve the problem until 14:00) . If the user has not completed learning the Q1 problem by 14:00, the review control unit 12 may recognize the Q1 problem as an uncompleted problem and delete the Q1 problem so that it cannot be re-learned or reviewed in the future. . In the case of an incomplete study problem, the review control unit 12 may delete the corresponding uncompleted problem (Q1 problem provided at 8 o'clock on May 1) from among the plurality of problems stored in the database unit (not shown).

Afterwards, the provider 11 can provide Q2, the second problem of today's problem, when the number is 14 on May 1. The user may be able to learn about the Q2 problem only until 20:00, when the next problem, the Q3 problem, is provided. If the user has completed learning the Q2 problem before 20:00, the review control unit 12 recognizes the Q2 problem as a completed problem, and thus preset the Q2 problem, which is a completed problem, as described later to enable future re-learning and review. Review period information can be repeatedly provided as review problems according to the review period within the review period.

Afterwards, the provision unit 11 can provide Q3, the third problem of today's problems, at 20:00 on May 1. Users may be able to learn about the Q3 problem only until the next problem, the Q1 problem (this means the Q1 problem provided at 8 o'clock on May 2), is provided until 8 o'clock the next day. If the user has not completed learning the Q3 problem before 8:00 on May 2, the review control unit 12 recognizes the Q3 problem as an uncompleted problem and deletes the Q3 problem so that it cannot be re-studyed or reviewed in the future. It can be handled. Afterwards, the provision unit 11 can provide Q1, the first problem among today's new problems, at 8 o'clock on May 2nd.

The review control unit 12 deletes incomplete learning problems, so that in the case of incomplete learning problems, the problems disappear and learning cannot be done again in the future. This app (language learning method) provided by the device 10 may have a number of features, including the feature of inducing regular learning by deleting incomplete learning problems so that re-learning and review are not possible. ', as an example, can be referred to as the first feature of this app. That is, according to the first feature, the device 10 provides problems at a set time every day, but if “learning is not completed” before the provision time of the next problem, the problem of incomplete learning occurs the moment the provision time of the next problem arrives. It can be deleted so that it disappears and learning becomes impossible. Accordingly, it may become impossible to review or re-learn sentences that have not been 'learned' (incomplete learning problems) in the future.

In other words, according to the first feature, the effective time (effective learning time) of today's problem in this application may mean the time until just before the time of the next problem. In other words, the valid time of today's question means before the time of the next question, so for example, if Q1 is provided at 08:00, Q2 is provided at 14:00, and Q3 is provided at 20:00, Q1 disappears at 14:00. Q2 is provided, and similarly, Q2 disappears at 20 o'clock and Q3 can be provided. At this time, if there is a review problem in front of today's problem, you can make all the previous review problems disappear together when today's problem disappears.

If you say you can learn a problem at any time, the average learner will develop the habit of putting off learning until later. Focusing on this problem, the present device 10 provides the function corresponding to the first feature, thereby enabling the user (learner) to control the habit of postponing learning to a later date and enable learning on a regular and consistent basis.

The device 10 can provide three problems as today's problems at set times every day (for example, 8:00, 14:00, and 20:00). At this time, for each of the problems provided every day (each of the three problems in today's problem), the valid time for learning (effective learning time) can be set to the time before (immediately before) the time when the next problem is provided. In other words, this device 10 can provide problems three times a day (one problem each at 8:00, 14:00, and 20:00), and it is possible to provide problems that are not 'study complete' before the next problem is provided. In this regard, by deleting the problem so that it disappears, it is possible to make it impossible to study the problem (incomplete learning problem) in the future and to make it impossible to review it later.

As mentioned above, for example, when the Q1 problem is provided at 8 o'clock, if the user does not 'complete learning' the Q1 problem before 14:00, which is the time when Q2 is provided, the review control unit 12 You can delete Q1 problems (incomplete learning problems) so that you can never re-study or review incomplete problems in the future. Q2 may then be provided at 14:00. This device 10 can improve the user's habit of delaying learning about problems provided every day to a later date, and thereby induce regular and steady learning. In other words, this device 10 can induce regular learning by a user who performs language learning through this device.

When one of a plurality of problems in today's problem is provided, the review control unit 12 determines whether the user has completed learning for one of the provided problems (i.e., whether the user has completed learning for one of the provided problems). You can judge. The review control unit 12 repeatedly provides study in accordance with the review cycle within a preset review period to enable future re-study and review for study-complete problems, while for un-study problems for which study has not been completed, re-study and review at a later date. It can be deleted so that it cannot be reviewed.

At this time, when determining whether or not learning has been completed for a provided problem, the review control unit 12 performs a 'problem solving process, a correct answer confirmation process, and a review process' by the user for a provided problem, as shown in FIG. 2. and correct answer confirmation process', it can be determined that learning of a provided problem has been completed. In other words, the completion of learning at our institute means a total of 4 steps as follows: “Problem solving process (step 1) → Correct answer confirmation process (step 2) → Review process (step 3) → Correct answer confirmation process (step 4)” This may mean that all execution has been completed.

For example, the provider 11 displays the same problem as shown in (a) of FIG. 2 as the second problem (Q2) among today's problems on the screen of the display unit (not shown) at 14:00 on May 1. It can be provided to be displayed. At this time, in relation to the provided second problem (Q2), the user solves the problem on the screen shown in (a) of Figure 2, performs the problem solving process (step 1), and then provides the correct answer as shown in (b) of Figure 2. Perform the correct answer confirmation process (step 2), and then perform the review process (step 3) as shown in (c) of Figure 2, and then perform the review process (step 3) for the reviewed problem as shown in (d) of Figure 2. When the correct answer confirmation process (step 4) of checking the correct answer is performed, the review control unit 12 determines that the user has completed learning the provided second problem (Q2) and marks the second problem (Q2) as a learning complete problem. It can be recognized.

In other words, the learning method for each of the three problems (problem of the day) provided every day is "Problem solving process (step 1) → Answer checking process (step 2) → Review process (step 3) → Answer checking process (step 4) )", learning can be accomplished in a total of four steps. In other words, when one of a plurality of problems in today's problem is provided, the review control unit 12 completes learning of one of the provided problems only if learning is completed through a four-step process for one of the provided problems. It can be recognized as a problem. The review control unit 12 may recognize a problem in which at least one of the four steps has not been performed as an uncompleted learning problem.

The control unit (not shown) can control the screen display (screen display on the display unit) of today's problem provided by the providing unit 11 and the review problem provided by the review control unit 12. At this time, the control unit (not shown) is operated when the user performs problem solving for today's problem or review problem (i.e., in the case of today's problem, this means performing the problem solving process, and in the case of review problem, it means the review process). ) If an incorrect answer is detected, the correct answer cannot be confirmed immediately. It can be controlled so that the correct answer can be confirmed only after retrying the problem at least three times.

That is, the control unit (not shown) can control the display (screen display) of the screen displayed on the display unit (not shown). The control unit (not shown) may control the screen display of today's problem provided by the providing unit 11 and/or the review problem provided by the review control unit 12.

At this time, the control unit (not shown) can control so that if the user answers incorrectly during the problem solving and reviewing process, the correct answer cannot be confirmed immediately, and the correct answer can be confirmed after retrying the problem at least three times. This device 10 can improve the user's learning efficiency. In this way, the 'feature that allows confirmation of the correct answer after at least three retries' can be referred to as the second feature of this app, as an example. According to this second feature, the device 10 can prevent the user from checking the correct answer without sufficient thinking, thereby effectively improving learning efficiency.

In other words, the control unit (not shown) performs learning (problem solving) on a problem provided by the providing unit 11 (for example, the Q2 problem) during the four-step process described above. If the user writes an incorrect answer during the problem-solving process (step 1), the correct answer confirmation process (step 2) is not immediately possible, but rather a re-solving opportunity is provided to solve the Q2 problem with an incorrect answer at least three times (i.e. , 3 or more replay opportunities) can be provided.

Accordingly, when the user first solves the Q2 problem provided in Today's Problem and gets it wrong (i.e., gets it wrong in step 1 of the problem-solving process), the control unit (not shown) performs two re-answers, but the answer is still wrong, and at this time, the correct answer is given. When a request for confirmation is made, control can be made so that confirmation of the correct answer is not possible as at least three replays are not performed (i.e., control is made so that the second step, which is the process of confirming the correct answer, cannot be performed). On the other hand, the control unit (not shown) can confirm the correct answer, for example, when the user solves the provided Q2 problem and gets it wrong, and then re-answers it 3 (or 4, etc.) times, but the answer is still wrong and a request is made to confirm the correct answer. It can be controlled so that the second step, which is the correct answer confirmation process, can be performed. In other words, the device 10 does not allow the user to immediately check the correct answer when the user solves a given problem and gets an incorrect answer, but allows the user to check the correct answer only after resolving the problem at least three times, thereby ensuring sufficient accuracy. It can lead to improved learning efficiency by preventing cases of checking the correct answer without thinking.

In the above description, as an example, when the user writes an incorrect answer in the problem-solving process (step 1), it is exemplified that the correct answer can be confirmed after providing at least three opportunities to re-answer, but the problem is not limited to this. The control unit (not shown) can enable the user to check the correct answer after providing at least three re-answer opportunities in the problem-solving process (step 1) as well as the reviewing process (step 3) when the user writes an incorrect answer. . In other words, when the user solves a given problem (one of a plurality of problems) and the user answers incorrectly in the problem solving process (step 1) and the review process (step 3), the control unit (not shown) immediately provides the correct answer. cannot be confirmed, the correct answer can be confirmed after at least 3 replay attempts.

Meanwhile, the review control unit 12 provides preset review period information to enable re-study and review in the case of a study-completed problem that has been confirmed to have been completed by the user among the plurality of problems in today's problem provided by the provision unit 11. can be given, and review problems corresponding to study completion problems can be provided repeatedly according to the review cycle within the preset review period information. Here, the description of the preset review period information can be more easily understood with reference to FIG. 6.

Referring to FIG. 6, the preset review period information may mean information that sets a period (review period) during which a review of a problem that has been completed has been reviewed. The review cycle may refer to information about the cycle (period, interval) between a plurality of review days set for a plurality of review days. The preset review period information may include a plurality of review days (review dates), number of review times (i.e., number of review days), and review cycle (interval information between review days). The review cycle in the preset review period information may mean cycle information of the date (review date) on which the study completion problem is provided as a review problem.

As an example, the pre-set review period information is 'D+1, D+3, D+7, D+15, D+30' from the day the problem was studied (learning date, learning completion date) for a study completion problem. , D+60, D+120, D+210, D+365, D+600, D+1000'. This setting value of review period information may be referred to herein as a default setting value.

Each of the problems provided by the device 10 (each of a plurality of problems in today's problem, review problems, etc.) may be given (set) a default setting value as review period information, but is limited to this. That is not the case. Each of the problems provided by the device 10 includes review period information, i) provided (set) with review period information changed/set by the user himself, as in the sixth feature of this app, which will be described later, or ii) ) As in the 4th feature of this app explained later, the changed review period information is applied depending on whether or not the review problem has not been completed, or iii) as in the 8th feature of this app explained later, the changed review period information is applied depending on whether the review question is correct or not. Changed review period information may be applied accordingly.

As an example, the plurality of review days in the preset review period information (default setting value) are the first review day (i.e., day 1, D+1), the second review day (i.e., day 3, D+3), and the third review day. It means review day (i.e., 7th day, D+7), etc., and you can see that the number of review days is set to 11. In addition, in the preset review period information, the review cycle is '2 (i.e., 2 days, the difference between the first and second review days), 4 (i.e., 4 days, the difference between the second and third review days), You can see that it is set to 8, 15, 30, 60, 90, 155, 235, 400 (i.e., 400 days, which is the difference between the 10th and 11th review days).

According to this, when a problem in today's problem is confirmed as a study completed problem, the review control unit 12 creates a review problem corresponding to the study completed problem (i.e., the same problem as the study completed problem as a review problem) as a preset problem. Review period information can be provided repeatedly for multiple review days within the preset review period information in accordance with the review cycle within the review period information.

For example, let's say that question Q1 (day 1 Q1) provided at 8 o'clock on May 1st (eg, day 1 of study) was confirmed (judged) to be a study completion question. In this case, the review control unit 12 adjusts the review problem corresponding to the 'Q1 problem, which is a problem completed on day 1', to the review cycle within the preset review period information on the 2nd day (D+1) and on the 4th day (D+). 3) When, on the 8th day (D+7), on the 16th day (D+15), … , can be provided on the 1001st day (D+1000).

As another example, let's say that the Q1 problem (3rd day Q1) provided at 8 o'clock on May 3 (for example, the 3rd day/3rd day of study) was confirmed to be a study completion problem. In this case, the review control unit 12 selects ‘Q1 problem, which is a study completion problem on the 3rd day,’ on the 4th day (D+1), 6th day (D+3), 10th day (D+7), and 18th day (D+ 15), Day 33 (D+30), Day 63 (D+60), Day 123 (D+120), Day 213 (D+210), Day 368 (D+365), Day 603 (D+600) , can be provided as a review problem on day 1003 (D+1000).

As mentioned above, the preset review period information given to the study completion problem in this device 10 is, for example, the default setting value is 'D+1, D' from the study completion date (learning date, study completion date) of the study completion problem. It can be set as follows: +3, D+7, D+15, D+30, D+60, D+120, D+210, D+365, D+600, D+1000. This preset review period information (i.e., review period information given to completed learning problems) can be set to have a review cycle that offsets the forgetting curve of memory (i.e., Ebbinghaus' forgetting curve), which is shown in Figure 7 It can be more easily understood by reference.

Referring to Figure 7, first of all, the Ebbinghaus curve (Ebbinghaus forgetting curve) means that H. Ebbinghaus studied memory or forgetting and presented a graph of the general forgetting tendency that appears over time.

The Ebbinghaus curve is considered a pioneering and classic result in memory research. Ebbinghaus devised a nonsense spelling to study forgetting. In other words, since common words or meaningful spellings are already in memory and can influence research, words (words with randomly arranged English consonants and vowels can be applied equally to everyone and minimize the impact on memory). For example, VAQ, MHI) were designed. After completely learning this series of meaningless letters to the experimental participants, the amount of forgetting was measured over time and created in a chart. This diagram is called the Ebbinghaus forgetting curve or Ebbinghaus curve.

According to the Ebbinghaus forgetting curve, forgetting occurs very rapidly immediately after learning, and in particular, 41.8% is forgotten within 20 minutes immediately after learning. In other words, forgetting occurred most quickly immediately after learning. According to these results, it can be concluded that repetitive learning and distributed learning performed several times regularly at intervals are very effective in order to remember the learned content for a long time.

Accordingly, in order to review completed learning problems, the review control unit 12 uses the 'preset review period information' given to completed learning problems to have a structure in which the review period (interval between review days within the review period information) increases as time passes. You can set it.

The 'preset review period information' considered in the device 10 may be set in a structure in which the review period (interval between reviews) increases as time passes. In other words, the pre-set review period information is set in a structure in which the rate at which the accumulated number of repetitions increases decreases as time passes (i.e., the cumulative number of repetitions that accumulates the number of review times for review days that are repeated over time) It can be set in a structure where the rate of increase in value gradually decreases. This device 10 can provide the user with a review cycle of the review period information set in this way so that the user can regularly and repeatedly perform a review (solution of the review problem) of the study completed problem. The solution to the review problem) can be provided so that the review progresses to offset Ebbinghaus' forgetting curve.

In FIG. 7, the 'Jeo Ki-young repetition curve' shows the time when review is performed using the language learning/review method provided by the device 10 (i.e., a method of providing review problems with a review cycle of preset review period information). It shows the amount of memory (or tendency to forget) in the form of a graph as it passes. In the graph of FIG. 7, the horizontal axis represents the passage of time, and the vertical axis represents change information in memory amount or number of repetitions (in particular, the cumulative number of repetitions accumulated by the number of repetitions). According to this, while general learning tends to decrease the level of memory retention for learned content over time, as shown in the Ebbinghaus forgetting curve, when language learning is performed using the review method using this device (10), As time passes, the number of repetitions (number of reviews) accumulates, and the period of memory retention increases accordingly. As the repetition cycle (review cycle) increases accordingly, the level of memory retention decreases even with minimal repetition (review). It can be seen that the highest memory efficiency is maintained without doing so.

This device (10) does not have a structure that allows review of study completed problems to be done every day, but a structure in which the review cycle gradually increases as time passes, so that review is conducted regularly and repeatedly in accordance with the review cycle of the preset review period information. It can be provided to make it happen. Reviewing a specific problem every day (i.e. reviewing it every day) can easily tire a learner and is very inefficient in terms of helping memory (i.e. maintaining memory). In order to solve this problem, the present device 10 allows repeated learning to occur at a review cycle of information during a preset review period according to the pattern of memory loss (according to the shape of Ebbinghaus' forgetting curve), rather than repeating every day. Learning/review can be done to achieve the highest memory efficiency with minimal repetition.

In this way, the preset review period information may be set in a structure in which the review cycle (interval between review days) increases as time passes. In other words, according to the default setting value of the preset review period information, the review period within the preset review period information is equal to '2, 4, 8, 15, 30, 60, 90, 155, 235, 400', so review You can see that the cycle interval is set to increase as time passes (goes backwards).

According to this, according to the sixth feature of this app, which will be described later, in this device 10, the user sets the value of the review period information (preset review period information) assigned to each problem (specific problem) at the user's own discretion. It can be provided to be freely changed/configurable. At this time, when the user tries to change the setting value of the review period information given to each problem, the review control unit 12 sets the review period for a plurality of review days in the review period information (in particular, the interval between two consecutive review days). ), it can be controlled so that it is impossible to set (change) the rear review cycle, which is located relatively in the rear, to a shorter cycle (interval) than the front review cycle, which is located in the front. In other words, the review control unit 12 can control so that when the user changes the setting value of the review period information for a study completion problem or a review problem, the later review cycle is set to a shorter cycle than the front review cycle.

By way of example, the review control unit 12 allows the user to set the review period information for a specific problem (one of the study completion problems or review problems) to 'D+1, D+3, D+7, D. +10, D+15, … 'You can control it so that it cannot be changed (set). Here, the posterior review cycle is 3 days (i.e., the gap between D+7 and D+10 is 3 days), and the front review cycle is 4 days (i.e., the gap between D+3 and D+7 is 4 days). Therefore, since the rear review cycle can be said to be shorter than the front review cycle, it may not be possible to set this review cycle in the device 10. In this way, the device 10 sets the setting value of the preset review period information so that the review period becomes longer toward the rear compared to the front (i.e., the review period on the rear side is set to be longer than the review cycle on the front side), thereby storing the memory. When this becomes blurred, repeated learning (review) is possible, that is, repeated learning (review) can be done to achieve the highest memory efficiency with minimal repetition, thereby enabling the most effective language learning.

At this time, when the review control unit 12 provides a review problem for a study completion problem (for example, 'Q1 problem, which is a problem completed on day 1') according to the review cycle within the preset review period information, the study completion problem is selected as today's problem. Review date within the review cycle, taking into account information (i.e., information on which question it corresponds to among Q1, the first problem, Q2, the second problem, and Q3, the third problem). Among today's problems provided on the relevant review day (i.e., Q1 problem among today's problems provided on the relevant review day) that corresponds to the same information as the above-mentioned study completion problem, You can provide review questions ahead of time.

In other words, the review control unit 12 individually (independently) for each of the plurality of problems in the problem of the day provided repeatedly every day, depending on whether each problem is a completed problem or not, and for each problem recognized as a completed problem. ) Preset review period information can be given.

For example, when the review control unit 12 completes learning of Q1 problem, it can provide review problems of the Q1 problem that has been studied prior to today's problem Q1 even when it is reviewed later. Likewise, when the Q2 problem is completed and a review problem of the Q2 problem for which the learning has been completed is provided later, the review control unit 12 is provided by the provision unit 11 on the date on which the review problem is provided (one review day among a plurality of review days). Before Q2 of today's problems provided by ), review problems (review problems of Q2 problems that have been studied) can be provided before Q2 of today's problems.

According to this, when providing today's problem, if a review problem exists, the device 10 may provide the review problem first and then provide today's problem later. When providing today's problem every day, if at least one review problem to be provided already exists, the device 10 first provides the existing review problem so that the user solves it first, and then solves all the review problems. As long as it is possible to provide the problem of the day.

In other words, when providing today's problem every day, the provision unit 11 provides the problem of the day, if there is a review problem provided by the review control unit 12 on that day (one day of each day). , Today's problems can be provided on the same day after the review problems provided on the same day. When providing today's problem on the same day, if there is at least one review problem provided on that day, the provision unit 11 provides today's problem only if it is confirmed that the user has completed reviewing at least one review problem provided on that day. can be provided.

In particular, if there are a plurality of review problems provided by the review control unit 12 on the same day, the provision unit 11 checks whether the user has completed reviewing all of the plurality of review problems provided on that day (i.e., whether the user has completed reviewing all of the plurality of review problems provided on that day) (check whether the user has completed reviewing the problem), and only if it is confirmed that the user has completed reviewing all of the multiple review problems provided on that day, today's problem of the day can be provided. At this time, before providing the problem of the day, if there are a plurality of review problems provided on that day, the provision unit 11 sequentially (sequentially) reviews the plurality of review problems, starting with the problem that was studied the oldest among the plurality of review problems. After providing the problem, you can provide the problem of the day for that day. According to this, the device 10 can provide today's problem of the day only when the user has completed reviewing all review problems (review problems corresponding to at least one study completed in the past). This device 10 can enable the user to solve today's problem of the day only after solving all the review problems.

The provision unit 11 determines whether the user has completed reviewing the review problems (review problems corresponding to the study completion problems) provided according to the review cycle within the preset review period information (i.e., review completion of the review problems). When determining whether or not), as shown in Figure 3, only when the 'review process (step 1) and the correct answer confirmation process (step 2)' are performed by the user for the provided review problem, the provided review problem is It can be judged that the review has been completed. In other words, the completion of review of review problems in this application means 'performing the review process (step 1) of providing a review problem and performing a solution to the review problem as shown in (a) of Figure 3, and then As in (b), this may mean a case where a total of two steps (steps 1 and 2) have been completed, including the correct answer confirmation process (step 2), which checks the correct answer to the review problem.

That is, in this device 10, the review method can be comprised of a two-step process (reviewing process and correct answer confirmation process), and learning of today's problem can be done after reviewing the review problem. If there are multiple review problems, the device 10 sequentially reviews the review problems from the most recently completed review problem to the most recently completed review problem, and then allows the user to study today's problem. can be provided.

In addition, the control unit (not shown) performs a review process ( If the user writes an incorrect answer in step 1), the correct answer confirmation process (step 2) is not immediately enabled, but rather, the incorrect answer is checked, similar to the incorrect answer processing process described in the problem-solving process of today's problem (step 1) described above. You can provide opportunities to re-solve the review problems you have written at least three times (i.e., opportunities to re-solve the review problems three or more times).

Figure 4 (i.e., Figures 4a and 4b) shows an example of a process in which today's problem of the 17th day (that day's problem of the day) is provided.

Referring to FIG. 4, for example, let's say that the user has completed learning all of today's problems (three problems Q1, Q2, and Q3) provided every day, especially the second problem (Q2). In this case, when the 17th day arrives, you can see that there are a total of 4 review problems that need to be reviewed on the 17th day. That is, the review problems provided by the review control unit 12 on the 17th day include review problems of the Q2 problem that was studied on the 2nd day (i.e., Q2_(2nd day)_review), and Q2 problems that were studied on the 10th day. review questions (i.e., Q2_(10th day)_review), review questions of Q2 questions completed on the 14th day (i.e., Q2_(14th day)_review), and review questions of Q2 questions completed on the 16th day. (i.e., Q2_(Day 16)_Review), it can be confirmed that there are a total of 4.

In this case, as shown in FIG. 4A, the provision unit 11 first provides 4 review problems before providing today's problem of the 17th day (i.e., Q2_(day 17)) and then provides 4 review problems. When it is determined that the user has reviewed all the problems, today's problem for the 17th day can be provided. At this time, in providing the four review problems, the provision unit 11 may provide the four review problems sequentially (one after the other) by prioritizing problems with older study completion dates. In other words, the provision unit 11 can sequentially provide 'Q2 review problems on the 2nd day → Q2 review problems on the 10th day → Q2 review problems on the 14th day → Q2 review problems on the 16th day' and then provide today's problem on the 17th day. there is.

At this time, before today's problem of the 17th day is provided by the providing unit 11, the review control unit 12 provides each of the four review problems sequentially, so that each review problem is selected through the 'review process (step 1). ) and the correct answer confirmation process (step 2), the review problem can be recognized as completed and the next review problem can be provided. If it is confirmed that all four review problems have been reviewed, the provision unit 11 can provide today's problem Q2 for the 17th day. At this time, the review control unit 12 performs the above-described four-step process (i.e., a four-step process including a problem-solving process, a correct answer confirmation process, a review process, and a correct answer confirmation process) for today's problem Q2 on the 17th day. In this case, today's problem Q2 on the 17th day can be recognized as a study completion problem and provided as a review problem according to the review cycle within the preset review period information.

In other words, the review problem that comes before today's problem (Day 17, Q2) can be as follows, for example, assuming that all problems have been studied without missing anything. First of all, since this is the 17th day problem, there are a total of 4 problems as mentioned above (i.e., the 2nd day (D-15), the 10th day (D-7), the 14th day (D-3), and the 16th day (D-1). There can be a total of 4) including the problem of ). Therefore, the user must solve and complete the review by solving all four review problems in order to receive today's problem (Q2 of the 17th day) and solve (learn) the problem.

According to this, when there are a plurality of review problems to be reviewed today (the same day as one of the plurality of days), the device 10 allows the user to study the question that was learned the longest ago (i.e., the first question among the plurality of review problems). A plurality of review problems can be provided sequentially in order of study completion date so that review can be performed sequentially (to perform problem solving for review problems), starting with review problems corresponding to completed learning problems. The device 10 allows the user to learn today's problem (i.e., solve today's problem) only by solving all of the plurality of review problems (i.e., only by completing all of the plurality of review problems). so that) can be done.

In other words, if a plurality of review problems exist before providing today's problem, the device 10 provides today's problem only when it is confirmed that all review problems have been completed by providing a plurality of review problems. can do. This device 10 can maximize the learning effect by preventing the user from skipping review of problems that have been studied in the past (study completed problems). In other words, when there are multiple problems to be reviewed, the device 10 can allow the user to review the problem learned most recently and then solve the next review problem. All provided review problems must be solved to solve today's problem. It can be done to enable learning. As such, the 'feature of allowing today's problem to be learned only by solving all of the multiple review problems' can be referred to as the third feature of this app, as an example. In other words, according to the third feature of this app, when providing a problem, the device 10 can ensure that if a review problem exists before providing today's problem, all the review problems must be solved to provide today's problem. there is. In other words, the device 10 can ensure that the user cannot solve today's problem without solving (skipping) the review problem.

In addition, the review control unit 12 provides review problems corresponding to study completion problems in accordance with the review cycle within the preset review period information (i.e., repeatedly provides review questions corresponding to each of the plurality of review days within the preset review period information). ), If it is confirmed that the user has written an incorrect answer more than a preset number of times (for example, 3 times) to a review question provided on one of the plurality of review days within the preset review period information, enter the wrong answer more than the preset number of times. Review problems that are confirmed to have been completed can be recognized as uncompleted review problems. Thereafter, when an incomplete review problem is recognized, the review control unit 12 increases the review cycle of the preset review period information assigned to the review problem corresponding to the uncompleted review problem by +1 day compared to the review cycle of the preset review period information. It can be changed to a modified review cycle. Accordingly, the review control unit 12 can repeatedly provide review problems corresponding to incomplete review problems according to the changed review cycle.

At this time, the device 10 allows the user to immediately check the correct answer when the user solves a specific problem (one of the problems of the day or a review problem) provided by the device 10 and writes an incorrect answer. Rather, it is possible to check the correct answer after providing the opportunity to replay at least three times. Therefore, in the above description, the preset number of times that serves as a standard for recognizing a review problem as an incomplete review problem can be set to 3 times (that is, 3 times, the same as the number of times replay opportunities are provided).

In this way, 'when a review problem is recognized as an incomplete review problem, the feature of providing a review problem by applying a changed review cycle in which the review cycle of the review problem is increased by +1 day' can be referred to as the fourth feature of this app as an example. You can. According to this fourth feature, the device 10 can increase learning effectiveness by preventing users (learners) from developing careless learning habits.

In other words, the review control unit 12 provides review problems according to the review cycle within the preset review period information (this is not a review problem provided in the three-step review process that goes through when solving today's problem, but rather a review problem provided in today's problem). Upon completion of this, if the answer is incorrect 3 times (meaning a review problem provided for reviewing the completed learning problem) (since confirmation of the correct answer is possible after 3 incorrect answers), review the review problem for which the wrong answer was entered more than 3 times This can be considered as not completed (i.e., recognized as an incomplete review problem) and provided as a review problem again the next day, and subsequent reviews can also be provided with a delay of 1 day.

At this time, when the review control unit 12 allows the user to solve the review problems provided according to the review cycle, the learner does not type the correct answer as in the 9th feature of this app described later, but means the correct sentence. Review can be done in a simple way (simple answer input method) by clicking on multiple buttons divided according to group (i.e., multiple split buttons (pb)). According to the ninth feature of this app, the device 10 can shorten (shorten) the time required to solve review problems, and the probability of getting the correct answer by pressing a plurality of split buttons is lowered by directly typing the correct answer. Since it is much higher than the probability of getting a correct answer, rather than just skipping a review question incorrectly, the review question with the wrong answer is provided again after +1 day, preventing people from carelessly solving the review question with a high probability of getting the correct answer. You can.

For example, the preset review period information is 'D+1, D+3, D+7, D+15, D+30, D+60, D+120 from the learning completion date (learning date, learning completion date). , D+210, D+365, D+600, D+1000', the review control unit 12 returns the study completed problems on March 1st to March 2nd (D+1). , March 4 (D+3), March 8 (D+7), March 16 (D+15), etc. can be provided as review questions.

At this time, the user answered the review question provided on March 2nd correctly (in this case, the review control unit 12 may recognize the review question provided on March 2nd as a review completed question), and on March 4th. If the provided review question was incorrectly answered (i.e., incorrectly answered), the review control unit 12 may recognize the review question provided on March 4 as an incomplete review question in which the review has not been completed. In this way, if the review problem provided on March 4th is recognized as an uncompleted review problem, the review control unit 12 provides the review problem corresponding to the uncompleted review problem according to the preset review cycle, and then returns the original question on March 4th. Although review problems must be provided on March 8, by applying a changed review cycle that increases the pre-set review cycle (i.e., the review cycle within the pre-set review period information) by +1, the review problems will be provided on March 4th and then March. Review questions can be provided on the 5th. If the review problem on March 5th is recognized as a review completed problem, the review control unit 12 may provide the review problem on March 9th, March 17th, etc.

In other words, if the review problem provided on March 4 (D+3) is recognized as a review completed problem, the review cycle for the review problem is set to 'D+3 (March 4), D+7' as the default setting. (March 8th), D+15 (March 16th), D+30 (March 31st), D+60, etc.' On the other hand, if the review problem provided on March 4 (D+3) is recognized as an incomplete review problem, the review cycle is changed to increase by +1 day, so the review cycle for the review problem is 'D+4 ( It may be set as 'March 5th), D+8 (March 9th), D+16 (March 17th), D+31 (April 1st), D+61, etc.'

In other words, if the review period is D+1, D+3, D+7, D+15 from the study date, problems learned on March 1st will be answered on March 2nd, March 4th, March 8th, and 3rd. Review may come on the 16th of the month. At this time, if the user gave the correct answer to the review question on March 2, and the user answered incorrectly more than three times in the review question on March 4, the review control unit 12 answers the review question on March 4. It can be treated as an incomplete review problem and provided as a review problem again on March 5th, and review problems scheduled to come after that can also be controlled to be delayed by one day to March 9th and March 17th. In other words, according to the original review cycle, review problems should be provided on March 8th, March 16th, etc., but as everything is delayed by one day, review problems can be provided on March 9th, March 17th, etc. At this time, the only difference between the 'review cycle before change' before the review cycle is changed and the 'review cycle after change' after the review cycle is changed is that the date is delayed by +1, and the interval between cycles remains the same. You can.

For example, with reference to FIG. 4B, when the user completes learning of the Q2 problem on day 1 (i.e., Q2_(day 1)), the review control unit 12 reviews the Q2 problem on day 1 for which the learning was completed within the preset review period information. Depending on the cycle, review problems can be provided on the 2nd, 4th, 8th, and 16th days. At this time, for example, if the user completes the review of the review questions provided on the 2nd and 4th days by answering the correct answers, and the review question provided on the 8th day (Q2_(Day 1)_Review) is recognized as an incomplete review because the review questions provided on the 8th day were answered incorrectly more than 3 times. , the review control unit 12 may apply a changed review cycle in which the review cycle of the review problem corresponding to the incomplete review problem (i.e., the review problem of the Q2 problem on Day 1) is increased by +1. Accordingly, after the review problem provided on the 8th day is recognized as an incomplete review problem, the review control unit 12 may provide the next review problem provided on the 8th day, not on the 16th day, but on the 9th and 17th days, etc. In other words, according to the original review cycle, the review problem of the Q2 problem of the first day should be provided on the 16th day after the 8th day, but as the review problem of the 8th day is recognized as an incomplete review problem, the review control unit 12 provides the review problem provided on the 8th day. After it is recognized as an incomplete review problem, a review problem of the Q2 problem from Day 1 is provided on the 9th day, and if it is confirmed that the review problem provided on the 9th day has been completed, a review problem can be provided on the 17th day. According to the fourth feature of this app, the device 10 can prevent careless study habits and enable effective learning.

The device 10 does not simply allow the user to study today's problems anew every day, but allows the user to first review previously studied problems (study problems) before learning new today's problems. This device 10 provides the ability to solve a new problem of the day only when all of these review problems have been reviewed (that is, if at least one review problem out of a plurality of review problems has not been reviewed, a new problem of the day can be solved). By making it impossible to learn the language itself, language learning is conducted in a structure that prevents review of problems completed in the past from being skipped, thereby maximizing the acquisition effect of language learning.

In addition, when the review control unit 12 provides a review problem and then allows the user to solve the review problem, the user does not directly type in the correct answer to the provided review problem, but instead inputs the correct answer to the provided review problem, for example (a) in FIG. 3 ), a selection input for selecting (clicking) a plurality of division buttons (pb) already created by dividing the correct answer sentence (i.e., the correct sentence) for the provided review problem into a plurality of areas according to the semantic group as shown in It can be provided so that the correct answer can be input through.

Here, the review problem provided so that the correct answer can be input by selecting input to a plurality of division buttons (pb) may mean a review problem corresponding to a study completion problem, as shown in (a) of FIG. 3, for example. It is not limited to this, and may refer to problems (review problems) provided in the review process corresponding to step 3 when learning today's problem, as shown in (c) of Figure 2.

In other words, when the review control unit 12 provides a review problem that allows the user to review, for example, as shown in (a) of FIG. 3, the review control unit 12 provides problem statement information (t) of the problem to be reviewed, and the user You can provide a review problem that includes an answer input box where you can enter the correct answer corresponding to the problem statement (t). At this time, the correct answer input field is provided in the form of a plurality of split buttons (pb) created by dividing the correct answer sentence into a plurality of areas according to the semantic group in relation to the correct answer sentence (correct answer sentence) for the problem statement information (t). It can be. The user can solve the review problem (enter the correct answer) by selecting the plurality of split buttons (pb) in order according to the sentence of the correct answer they think. In other words, the user can enter information about the sentence he or she believes to be the correct answer by sequentially clicking on the plurality of split buttons (pb) according to the sentence he or she considers to be the correct answer.

In the example of Figure 3 (a), it can be seen that 10 division buttons are provided as a plurality of division buttons (pb). The semantic group that serves as the basis for dividing the plurality of split buttons (pb) refers to a group with meaning, and may mean a group consisting of a collection of at least one word. For example, the plurality of split buttons (pb) include 'I' as the first split button, 'If' as the second split button, 'a lot of' as the third split button, and 'would have saved' as the fourth split button. etc. may be included.

According to this, the review control unit 12 provides review problems in which the correct answer can be entered by selecting a plurality of split buttons (pb), so that when solving the review problem, the user (learner) directly types and inputs the correct answers one by one. Instead, you can enter the correct answer by simply clicking on several buttons that divide the correct sentence according to its meaning group. This device 10 provides review problems that allow correct answers to be entered through a plurality of split buttons (pb), thereby enabling reviewers to review more quickly by shortening the time required to solve review problems (i.e. The review time for review problems can be shortened), and the probability of getting the correct answer to a review problem when solving a review problem can be made much higher compared to entering the correct answer by typing directly. This 'feature that allows you to easily input the correct answer to a review problem by sequentially clicking on a plurality of split buttons (pb)' can be referred to as the ninth feature of this app, as an example.

This device 10 can preferably enable language learning centered on sentence learning. In other words, the device 10 may be a language learning device (a language learning device for sentence learning) in relation to language learning, especially for sentence learning. However, it is not limited to this, and the device 10 may be capable of learning words as needed in addition to sentence learning.

In addition, as mentioned above, the review control unit 12 is configured to enable re-study and review in the case of a learned problem that has been confirmed to have been completed by the user among the plurality of problems in the problem of the day provided by the providing unit 11. Information on the set review period can be provided, and review problems corresponding to study completion problems can be provided repeatedly according to the review cycle within the preset review period information.

At this time, the review control unit 12 can control the user (learner) to change or selectively select the setting value of the preset review period information at his or her own discretion. Here, the setting value of the multiple period information may include a plurality of review days (review dates), number of review times (i.e., number of review days), and review cycle (interval information between review days). The review control unit 12 provides the user with the ability to set and change the preset multiple-period information setting values assigned to each problem according to the user's own judgment, according to the importance, difficulty, level of mastery, etc. of each problem considered by the user. can do.

In the above explanation, it is exemplified that the subject for which the user can change the setting value of the pre-set review period information is a 'study completion problem (i.e., a study completion problem recognized as having completed learning of today's problem provided for the first time)'. It is not limited to this, and the user may change the setting value of the preset review period information for each of today's problems and/or review problems regardless of whether or not 'study has been completed'. At this time, since review of today's problem for which study has not been completed is not provided (i.e., not provided as a review problem), even if the setting value of the review period information is changed, it may not be reflected. In other words, a review period can be set before learning is completed, but if learning is not completed for a specific problem, the review period set for that specific problem may become meaningless.

That is, referring to FIG. 6, the review control unit 12 determines the 'importance, difficulty, and degree of mastery' for each problem given by the user, and when the user first studies each problem (i.e., on the day the problem is first received) (i.e., the day on which today's problem is provided) or in the middle of the review period (i.e., during the period when review problems for study-completed problems are provided), information on the review period assigned to the problem (this is information linked to the number of times of review) You can control to select/change the setting value.

In other words, when today's problem is provided by the providing unit 11, the review control unit 12 provides a review problem (review corresponding to a study completion problem) for each of today's problems provided and/or by the review control unit 12. When a review problem is provided, the user sets the value of the preset review period information for each problem (i.e., each problem of the day and/or review problem) to the value desired by the user at his/her own discretion. A review period setting function that can be changed or selected can be provided. In this way, the 'feature that allows the user to change the setting value of the review period information for each problem (i.e., for each problem such as a completed study problem or a review problem) based on his or her own judgment of importance, difficulty, and level of mastery' is As an example, this may be referred to as the sixth feature of this app.

For example, for problems that the learner judges to be too easy, unimportant, or already completely memorized (problems of the day, or review problems), the learner can freely select and change the setting value of the review period accordingly. You can. At this time, for example, when learning a problem for the first time (i.e., when receiving a new problem for the first time as today's problem), it may be set to the default setting, but even in this case, the review period can be changed to the user's preference. Additionally, the user may change the review period to the desired review period even in the middle of the review period.

In other words, the review control unit 12 may give, for example, a setting value of review period information as a default setting value for each of today's problems. At this time, the default setting value is, as an example, the setting value of the previously set review period information (i.e., 'D+1, D+3, D+7, D+15, D+30, D+60, D+120, It may mean D+210, D+365, D+600, D+1000'). At this time, when a user input is made to the review period setting button provided in the area of today's problem as shown in the left picture of FIG. 6, the review control unit 12 displays the button shown in the right picture of FIG. 6 on the display unit. In the same way, the review period setting screen can be displayed so that the user can change the setting value of the review period information given to the study completed problem (that is, changeable at the first study of the problem).

In addition, when the review control unit 12 provides review problems corresponding to study completion problems according to the review cycle in the information of the preset review period, the review control unit 12 includes a review period setting button as shown in the middle figure of FIG. 6. By displaying the problem on the display unit, when the user is provided with a review problem, the setting value of the review period information preset in the review problem can be changed (that is, changed in the middle of the review period).

When the user accesses the app (i.e., when the user's access is detected), the control unit (not shown) is provided so that problems that must be solved on the same day are displayed on the display unit (not shown) when the user's access is detected. 11) and the operation of the review control unit 12 can be controlled. Here, the problem to be solved on the same day may mean 'today's problem' provided by the provider 11 when at least one review problem does not exist on the day (today) when the user's connection is detected, and the user's If there is at least one review problem on the day the connection is detected (today), it may mean a 'review problem (particularly, a review problem that was completed the longest ago)' provided by the review control unit 12.

According to this, the device 10 can display review problems immediately when the user accesses the app (if there are no review problems to be reviewed that day, today's problems can be displayed immediately), The user must solve all of the provided review problems to be able to solve today's problem.

In other words, when the control unit (not shown) detects that the user has accessed the app, it does not cause a separate home screen to be displayed on the screen of the display unit (not shown) when the user's connection is detected, but rather a problem that must be solved on the same day. It can be controlled to be displayed directly on the screen of the display unit. As such, the 'feature that allows problems to be solved to be displayed on the screen immediately when accessing the app' can be referred to as the 7th feature of this app, as an example. According to the seventh feature of this app, this device 10 provides a mandatory language learning approach by this app, thereby preventing learning omissions (i.e., solving problems provided by this device without omission). (so that all can be solved) can be provided.

In general, most of the conventionally known learning-related apps display categories (icons) with the main functions of the app on the first screen (home screen). Accordingly, when the user selects a specific category among a plurality of categories, the selection In response, the function of a specific category selected by the user is provided to be performed.

However, such a conventional learning-related app provides functions for a specific category selected by the user among a plurality of categories (that is, the user selectively selects and receives only the desired information that the user wants to receive), so the present device As in (10), there is no 'compulsory provision of problems such as providing problems that have been studied in the past as review problems before providing today's problem', so compared to the learning effect by this device (10), It can be said that the learning effect is low.

As an example, let's say that on the home screen of a conventional learning-related app, a plurality of categories are provided, such as 'Solving Today's Problem', 'Solving Review Problem', etc. At this time, for example, if the user selects and learns only the 'Solve Today's Problem' category that provides new problems every day, the user will be able to learn only new problems every day. In other words, if the user does not select the 'Solve review problems' category, the user will not be able to review the review problems at all. In this way, it can be said that the learning effect of conventional learning-related apps whose home screens are provided in a category format is insufficient compared to the present device 10. This device (10) does not enable learning by going to the home screen and clicking on a specific category like a conventional learning-related app, but when the user accesses the app, the problem must be solved as soon as app access is detected without the user's choice. You can control it to be displayed right on the first screen, which reduces time wastage due to unnecessary processes and allows you to focus solely on learning the problem, thereby ensuring effective learning.

Meanwhile, as mentioned above, the review control unit 12 is configured to enable re-study and review in the case of a learned problem that has been confirmed to have been completed by the user among a plurality of problems in the problem of the day provided by the providing unit 11. Information on the set review period can be provided, and review problems corresponding to study completion problems can be provided according to the review cycle within the preset review period information (default setting value). Review period information may refer to information on the review cycle (information on the review cycle including review date and review number) in which review problems corresponding to study completion problems are repeatedly provided.

At this time, the review cycle in which the review problems are provided (i.e., the review cycle within the preset review period information set in the review problems) is determined by the user's correct answer to the provided review problems whenever the review problems are provided according to the review cycle. It can be adjusted (converted) differently depending on whether the solution to the review problem is correct or not (whether the answer is correct or not).

For example, the first problem of today's problem (the first problem, Q1) is provided at 8 o'clock on May 1st, and as the Q1 problem is confirmed as a study completion problem, review problems corresponding to the Q1 problem dated May 1st are provided. Let us assume that the information is provided according to the review period of the preset review period information (default setting value) for review. Below, the review period information set as the default setting (i.e., 'D+1, D+3, D+7, D+15, D+30, D+60, D+120, D+210, D For convenience of explanation, the review cycle (information on the preset review period set such as '+365, D+600, D+1000') will be referred to as the basic review cycle.

According to the basic review cycle, the review problem corresponding to the Q1 problem dated May 1 is the first review problem provided for the first review (i.e., the (n)th review problem, where n is a natural number and n can be 1). It can be provided at 8 o'clock on May 2nd (D+1). Next, if you follow the basic review cycle (i.e., do not adjust the review cycle to reflect whether or not you answer the review questions correctly), the review questions corresponding to the May 1st Q1 question will be provided for the second review. As a problem (i.e., (n+1)th review problem), it will be provided at 8 o'clock on May 4 (D+3), and as the third review problem (i.e., (n+2)th review problem), it will be provided on May 8 ( D+7) It will be provided at 8 o'clock.

At this time, the review cycle (i.e., D+1) preset for the first review question (i.e., (n)th review question) can be said to be 1 day, and this reflects the correct answer to the review question and determines the review cycle. It is a reference point that serves as a starting point for adjustment, and may be referred to differently as a standard review cycle (standard cycle), etc. That is, the review cycle (i.e., D+1) preset for the first review problem (i.e., (n)th review problem) is 1 day, and can be expressed as a reference point or a standard review cycle (reference cycle).

At this time, when the review control unit 12 provides review problems (for example, review problems corresponding to the Q1 problem dated May 1) according to the review cycle (basic review cycle) of the preset review period information, the review problem is provided. Shimada, depending on whether the user answers the current review question correctly, the provision cycle of the next review question provided after the current review question (i.e., the review cycle set for the next review question) is automatically customized and converted. (i.e., by dynamically and automatically converting), the next review problem can be provided according to the converted review cycle. Here, this review problem is the (n)th review problem provided and can be referred to as the (n)th review problem, and the next review problem is the (n+1)th review problem provided and can be referred to as the (n+1)th review problem. It can be. Here, n may be a natural number and may be applied as any one value of 1 or more.

In this way, depending on the user's correct answer to the review question (i.e., depending on whether the user answered the review question correctly or incorrectly), the review cycle of the next review question provided is automatically customized and converted based on a predetermined calculation method. ‘Feature (i.e., review cycle automatic conversion feature)’ may be referred to as the eighth feature of this app as an example. This setting/conversion of the review cycle of review problems can be applied individually to each problem provided by the device 10 (each completed study problem, each review problem).

When the review control unit 12 determines that the user has answered the correct answer to the current review question (i.e., the (n)th review question), the review control unit 12 operates the review cycle preset for the current review question before answering the correct answer (this is the previous review cycle). The period variation difference value can be calculated by multiplying the value of (may be indicated) by the multiplier applied for the preset correct answer. Afterwards, the review control unit 12 determines the review cycle set for the next review problem provided after the current review problem (i.e., the (n+1)th review problem), the calculated period change difference value, and the review cycle of the current review problem. By adding the value of the cycle date (i.e., the review date on which this review problem was provided), it is converted into a review cycle corresponding to the calculated total value, and the next review problem (i.e., (n+1)th review problem) is adjusted according to the converted review cycle. ) can be provided.

Here, the 'applied multiplier for correct answer', which is applied to change the review cycle for the next review problem every time you answer the current review problem correctly, is any of the values between 2 and 4 to set a more effective review cycle. It can be set to a value of . That is, the minimum value of the applied multiplier for a preset correct answer may be set to 2, and the maximum value may be set to 4.

For example, in this device 10, it may be more desirable to apply the value of 2 as the preset multiplier for correct answer each time the correct answer to this review problem is answered. However, it is not limited to this, and as another example, the preset multiplier applied to the correct answer to this review problem is any one value selected by the user among the values 2 to 4 (user selection value). This can be applied.

On the other hand, when the review control unit 12 determines that the user has incorrectly answered the correct answer to the current review question (i.e., the (n)th review question), the review cycle (previous review cycle) preset for the current review question before the correct answer is incorrect. ) can be calculated by multiplying the value of the standard review period (i.e., 1 day) by the value of the period variation difference. Afterwards, the review control unit 12 determines the review cycle set for the next review problem provided after the current review problem (i.e., the (n+1)th review problem), the calculated period change difference value, and the review cycle of the current review problem. By adding the value of the cycle date (i.e., the review date on which this review problem was provided), it is converted into a review cycle corresponding to the calculated total value, and the next review problem (i.e., (n+1)th review problem) is adjusted according to the converted review cycle. ) can be provided.

In other words, the review control unit 12 automatically changes (adjusts) the review cycle of the review question each time a review question is provided, taking into account the user's correct answer to the provided review question. i) If the correct answer to the current review question is answered, the next review question The review cycle for the next review problem provided is applied as a review cycle with a longer interval compared to the previous review cycle (i.e., the review cycle applied in this review problem) (i.e., by applying the preset multiplier for correct answers) Accordingly, a review cycle increased by the applied multiple of the pre-set correct answer is applied), while ii) if the correct answer to the current review question is incorrect, the review cycle for the next review question provided next time is applied so that the review cycle remains the same as the previous review cycle. (That is, as the standard review cycle (i.e., 1 day) is applied, a review cycle that maintains the previous review cycle can be applied.) A more detailed description of the eighth feature of this app is as follows.

The review control unit 12 controls the review cycle so that when the user answers the review question correctly, the subsequent review cycle increases compared to the current review cycle (for example, by applying a multiple of 2, 3, or 4, the review cycle is increased. ), and if the user gets a review question wrong, it can be controlled to maintain this review cycle by applying the standard review cycle (1 day, 1 multiple).

According to this, as a result, the review cycle for the review problem in the device 10 is determined as the user repeatedly performs the problem solving of the review problem (i.e., as the user repeats the review of the review problem), the Braille period changes over time. It can be controlled so that it is automatically converted (adjusted) in the direction of increasing. If the user makes a review problem incorrectly, the value of the previous review cycle is multiplied by the value of the standard review cycle (i.e., 1 day), so the previous review cycle (this is during the review of the repeatedly performed review problem) It may refer to the review cycle at the time of the most recent review, that is, when reviewing review problems for study completion problems multiple times, it may refer to the longest review cycle (the most recent review cycle) among those reviewed for the next time. You can provide problems (providing the next review problem that follows the review problem that was incorrect).

This device 10 provides the next review problem once again by applying the same review cycle as the previous review cycle when the user makes a review problem incorrectly, so that the user can use the review problem even at a time interval equal to the review cycle (i.e., the previous review cycle). The review cycle can be automatically converted by confirming that the memory is maintained and then proceeding to the next review cycle (i.e., a longer review cycle with wider intervals than the previous review cycle).

The review control unit 12 applies the value of the standard review cycle (i.e., 1 day) every time the user makes a review problem incorrectly, no matter how many times the user makes a review problem incorrectly, so that the review cycle that is converted (adjusted) is the previous review cycle. (That is, it can be maintained at the previous review cycle, which is the longest review cycle up to that time when the review was repeated multiple times in the past). In other words, the review control unit 12 can control it so that the next review cycle is not changed to be shorter than the current review cycle, no matter how many times the user gets the review questions wrong (that is, the review cycle itself is short). You may not lose).

Here, the immediately preceding review cycle (i.e., previous review cycle) may ultimately refer to a cycle in which it has been tested (verified) that the learner can 'maintain memory up to this level of the review cycle.' According to the eighth feature of this app, when the user makes a review question incorrectly (answers incorrectly), the review control unit 12 tests this review cycle when the question is wrong again (i.e., repeats the review cycle when the user gets it wrong) After solving the review problem), if you answer correctly when solving the review problem with the same review cycle applied again, you can apply a longer review cycle later. The review control unit 12 can change the rate of increase in the review cycle to gradually increase when the user successively answers the repeatedly provided review questions (i.e., gradually increases the review cycle, such as 1 time → 2 times → 3 times, etc.). (However, at most 4 times can be applied), according to the eighth feature of this app, the device 10 can achieve the highest learning efficiency with minimal review.

In this application, automatic adjustment (conversion) to the review cycle can be applied individually to each of the problems provided by the device 10 (each of the learned problems, each of the review problems). The number of reviews by the device 10 can be infinite, and for example, restrictions such as 'no more reviews after D+1000 days or D+3000 days' may not be applied. In other words, the device 10 can provide infinite review of completed problems as long as the user uses the app. Specific examples are as follows:

For example, i) Review problems that have been studied may be provided to D+1 from the day learning is completed according to the default setting value (according to the basic review cycle) (the review cycle at this time is 1 day and can be a reference point) there is).

ii) Afterwards, if you answer the review questions provided on D+1 correctly, the next review day can be D+3. In other words, if you answer the review questions provided on D+1 correctly, the next review questions can be provided on D+3. At this time, before answering the correct answer, x2 (preset answer application multiplier) is applied to the review cycle (previous review cycle, 1 day) preset in this review problem, so the cycle change difference value is '1 day x 2 = 2 days'. It is calculated as , and as a result, the total value is calculated as 3 days by adding the review cycle that was preset to this review question before answering the correct answer (i.e., 1 day, the previous review cycle) to the 2-day period difference value, so the next review date This could be D+3 days.

At this time, if you make a mistake in the review question provided in D+1, on the next review day, Therefore, as a result, the total value calculated by adding the value of the period variation difference value (1 day) and the review cycle date of this review problem (i.e., 1 day because the review problem incorrectly was provided in D+1) is 2 days. Therefore, the next review can be done at D+2 (that is, the next review problem can be provided at D+2).

iIi) If you answer the review questions provided on D+3 correctly, the next review date can be D+9. In other words, if you answer the review questions provided on D+3 day correctly, the review questions provided after D+3 days can be provided on D+9 days. At this time, before answering the correct answer, x3 (multiplier applied when correct answer) is applied to the review cycle (previous review cycle of 2 days) preset in this review problem, so the cycle change difference value is '2 days x 3 = 6 days. ', and as a result, the total value is calculated as 9 days by adding the value of the review cycle date of this review problem (i.e., D+3, so 3 days) to the cycle change difference value (6 days), so the next review date is D. It can be adjusted (converted) to +9 days.

At this time, if you make a mistake in the review questions provided in D+3, on the next review day, As a result, the total value calculated by adding the value of the difference in period variation (2 days) and the review cycle date of this review problem (i.e., 3 days because the review problem that was wrong was provided in D+3) is 5 days. Therefore, the next review can be done at D+5 (that is, the next review problem can be provided at D+5).

For example, let's say that a completed study problem was provided as a review problem on D+1 from the day the study was completed. The review cycle at this time is 1 day, which can be a reference point.

At this time, the review control unit 12 recognizes the next review day as D+3 because if the user has answered the review problem provided for D+1, x2 is applied as an example to the previous review cycle and 1 day x 2 = 2 days. Review questions can be provided again at +3.

Afterwards, the review control unit 12 recognizes the next review date as D+5 because if the user makes a mistake in the review question provided at D+3, x1 is applied to the previous review cycle and 2 days x 1=2 days, and D+ Review questions can be provided again in 5.

Afterwards, the review control unit 12 recognizes the next review date as D+9 because if the user has answered the review problem provided at D+5, x2 is applied to the previous review cycle as an example and 2 days x 2=4 days. Review questions can be provided again at +9.

Afterwards, the review control unit 12 recognizes the next review day as D+21 because if the user answers the review problem provided at D+9, x3 is applied to the previous review cycle as an example, and 4 days x 3 = 12 days. Review problems can be provided again.

Afterwards, the review control unit 12 recognizes the next review date as D+33 because if the user makes a mistake in the review problem provided at D+21, x1 is applied to the previous review cycle and is 12 days x 1=12 days, and D+ Review questions can be provided again in 33.

Afterwards, the review control unit 12 recognizes the next review date as D+45 because if the user makes a mistake in the review question provided at D+33, x1 is applied to the previous review cycle and is 12 days x 1=12 days, and D+ Review questions can be provided again at 45.

Afterwards, the review control unit 12 recognizes the next review date as D+69 because if the user answers the review question provided at D+45, x2 is applied to the previous review cycle and 12 days Review problems can be provided.

Afterwards, the review control unit 12 recognizes the next review date as D+93 because if the user makes a mistake in the review problem provided at D+69, the previous review period x1 is applied and 24x1=24 days, and the review date is D+93. Review questions can be provided again.

In this way, as in Example 1 and Example 2 described above, the review control unit 12 increases the review cycle if the review problem is correct, and conversely, if the review problem is incorrect, it maintains the previous review cycle as is (i.e., x1 is applied when the review problem is incorrect) , x1 ultimately only maintains the previous review cycle and does not make the review cycle shorter). Review can be provided according to the learner's current level of memory. In other words, when the review control unit 12 repeatedly provides review problems for study-completed problems, if the user matches the review problem (current review problem) provided this time, the review cycle (i.e., the period from this review problem to the next review problem) ) increases so that the next review problem is provided after a longer period of time than the previous review cycle. Conversely, if the user makes a mistake in the review problem provided this time, the previous review cycle is maintained (i.e., the review problem applied to the review problem provided this time) is increased. The cycle can be applied and maintained as is and the next review can be done, and review problems can be provided so that the learner can re-review according to the extent of the period (memory level) that the learner can currently remember.

At this time, in relation to the eighth feature of this app, as described above, if you answer the correct answer to this review problem, a preset multiplier applied for the correct answer (for example, a multiplier corresponding to any one of the values between 2 and 4, In other words, as a multiple of 2, 3, or 4) is applied, the subsequent review cycle (review cycle for the next review problem) can be increased according to the applied multiple. On the other hand, if the correct answer to this review question is incorrect, the value of the standard review cycle (i.e., 1 day) is applied, so the review cycle thereafter can be maintained as the previous review cycle.

In other words, when you answer a review question correctly, the subsequent review cycle increases by 2 times, 3 times, 4 times, etc., while when you answer a review question incorrectly, the subsequent review cycle is the previous review cycle x1 (multiple of 1). As this is applied, the previous review cycle may be maintained (i.e., the applied multiple may return to a multiple of 1).

At this time, if the user applies a continuously increasing multiplier like x (1→2→3→4→5→6→7→8→...) to the previous review cycle every time the user solves a repeatedly provided review problem, For example, when you get a review problem right every time, "D+1 (the review cycle at this time is 1 day, the multiple is x1, and becomes the reference point) → D+3 (1 day x 2) → D+9 (2 days x 3) ) → D+33 (6 days x 4) → D+153 (24 days x 5) → D+873 (120 days x 6) → D+5913 (720 days x 7) → D+46233 (5040 days x 8) →... "Like this, there may be a problem where the review cycle increases too exponentially and the effectiveness becomes too low. In other words, each time you answer a review problem, the multiplier applied (multiplier applied when answering a preset correct answer) is increased by 1 and applied as 'multiplier of 2, multiple of 3, multiple of 4, multiple of 5, multiple of 6, multiple of 7, etc.' If ordered, it can be reviewed only 7 times in about 16 years or 8 times in about 126 years (that is, review can only be done a very small number of times). No matter how well it is judged that the user (learner) remembers well by correcting the review questions each time, this method (automatic conversion of the review cycle) is too inefficient in the review cycle, or it returns to x1 due to a mistake in the middle. Even if we take this into account, there is a high possibility that the number of reviews will be too small.

Therefore, when the review control unit 12 performs the automatic conversion of the review cycle for the review problem, the multiplier applied each time the user answers the review problem correctly (the multiplier applied when the correct answer is preset) continues to be '2 multiple, 3'. Rather than applying it as a continuously increasing multiple such as 'multiplier, 4 multiple, 5 multiple, 6 multiple, 7 multiple, etc.', the maximum applied multiple (Maximum multiple) of the multiplier applied when answering a preset correct answer can be fixed. That is, the review control unit 12 may set the maximum application multiple (Max multiple) of the preset correct answer application multiple to a value of any one of 2 multiples, 3 multiples, and 4 multiples.

According to this, the review control unit 12 determines that if a multiple greater than 4 (multiple of 5, multiple of 6, etc.) is applied as the applied multiple for the preset correct answer, the review effect for the review problem will be reduced (i.e., the review (Considering that the structure makes it difficult to effectively review the problem), the maximum applied multiple (Max multiple) of the preset applied multiple for correct answer can be set to one of 2 multiples, 3 multiples, and 4 multiples. In this application, it may be preferable that a multiple of 2 is applied as the maximum application multiple, but it is not limited to this, and the user selects any one of 2, 3, and 4 so that it is fixedly applied, or the user Any one of the values selected by 2, 3, or 4 can be applied. At this time, the structure in which x1 is applied when a review problem is incorrect can remain the same.

In other words, the eighth feature of this app may refer to the function of the review control unit 12 to automatically change the review cycle of future review problems depending on whether the review problem was correct or incorrect for each problem. At this time, if the review question is correct, the review cycle can be increased, and if it is incorrect, the review cycle can be controlled to be maintained (same as the previous review cycle).

The way the review cycle increases is in the 'previous review cycle', with multiples continuing from x (1→2→3→4→4→4→1→1→...) to (2→3→4→4→4). It increases, but rather than increasing the multiplier endlessly, the maximum multiplier is selected (at this time, the maximum applied multiplier of the preset correct answer multiplier can be applied as any one value selected by the user among 2, 3, and 4. ) It is possible to control the review cycle from increasing to multiples larger than that.

The review cycle can be maintained at the previous review cycle by applying 'previous review cycle x 1'. In other words, even if the previous applied multiplier was 2, 3 or 4, if you get a review problem wrong, a multiplier reduced to x1 can be applied.

The review control unit 12 can allow review of review questions to proceed infinitely. In other words, the review control unit 12 can control the review to proceed infinitely when repeatedly providing study completed problems as review problems for review. According to this, in the present device 10, for example, restrictions such as 'no more review after D+1000 days or D+3000 days' may not be applied. An example of the 8th feature of this app is as follows.

When the maximum application multiple (Max multiple) of the pre-set correct answer is 2, the review cycle of the review problem provided repeatedly is as an example, according to the review problem and the error, 'previous review cycle x (1 → 2 → 2 →2→1→2→1→2→2→2→1→...)'. According to this, for example, the review cycle of review problems for study completion problems is "D+1 → D+3 (1 day x 2) → D+7 (2 days x 2) → D+15 (4 days x 2) → D +23 (8 days x 1) → D+39 (8 days x 2) → D+55 (16 days x 1) → D+87 (16 x 2) → D+151 (32 x 2) → D+279 (64 days x 2) → D It can be equal to +407 (128 days x 1) →... ".

When the maximum application multiple of the preset correct answer is 3, the review cycle of the review questions provided repeatedly is as an example, according to the mistake, 'previous review cycle x (1 → 2 → 3 → 3 → 1 →2→3→1→2→1→2→3→...)'. According to this, the exemplary review cycle of review problems for study completion problems is "D+1 → D+3 (1 day x2) → D+9 (2 days x3) → D+27 (6 days x3) → D +45 (18 days x1) → D+81 (18 days x2) → D+189 (36 days x3) → D+297 (108 days x1) → D+513 (108 days x2) → D+729 (216 days) x1) → D+1161 (216 days x2) → D+2457 (432 days x3) → ...”

When the maximum applied multiplier of the preset correct answer is 4, the review cycle of the review problem provided repeatedly is as an example, according to the mistake, 'previous review cycle x (1 → 2 → 1 → 2 → 3 →4→4→1→2→1→2→3→...)'. According to this, for example, the review cycle of review problems for study completion problems is "D+1 → D+3 (1 day x 2) → D+5 (2 days x 1) → D+9 (2 days x 2) → D +21 (4 days x 3) → D+69 (12 days x 4) → D+261 (48 days x 4) → D+453 (192 days x 1) → D+837 (192 days x 2) → D+1221 (384 days) x1) → D+1989 (384 days x 2) → D+4293 (768 days x 3) → ..."

In this way, according to the eighth feature of this app (i.e., the review cycle automatic conversion feature), the device 10 eventually applies 'x1' to the 'previous review cycle' no matter how many times the user gets the review questions wrong. Accordingly, the review cycle can be automatically converted so that the previous review cycle is maintained as is, but the review cycle itself is not shortened. In addition, if the user makes a review question incorrectly, the device 10 once again provides the previous review cycle (=last review cycle=longest review cycle so far), so that the time interval equal to the review cycle is maintained. After confirming that the memory is maintained, you can proceed to the next review cycle (= longer review cycle). In this institute, 'previous review cycle' can ultimately mean the proof value tested that the learner can 'maintain memory up to this level of review cycle', and in case of an incorrect answer, this review cycle is tested again and eventually further. You can proceed with a long review cycle.

In addition, when providing review problems (review problems corresponding to study completion problems) repeatedly, the review control unit 12 provides the current review problem provided this time, so that the current review problem is only a few days longer than the previous review problem provided before this time. Information (primary information) indicating whether it is a review question provided in can be provided along with this review question. At this time, the 'feature of providing review problems containing primary information' may be referred to as the 10th feature of this app, as an example.

That is, the review control unit 12 may include primary information when providing a review problem and provide a review problem including the primary information. Primary information may refer to information on the number of days that is the difference between the dates on which each of the previous review problems and this review problem were provided. As an example, let's say the previous review problem was provided at D+15, and the next review problem was provided at D+31. At this time, if the review problem provided in D+31 is referred to as this review problem, the primary information of this review problem may be the same as the 'Day 16' information. In other words, since the difference in days between D+15 and D+31 is 16 days, the primary information may be the same as ‘Day 16’ or ‘Day 16 Challenge’. Accordingly, the review control unit 12 may provide a review problem including primary information 'day 16' when providing the corresponding review problem to D+31.

For example, if the Max multiplier (i.e., the maximum application multiplier of the preset correct answer application multiple) is 2 (in this case, in the present device 10, the maximum application multiplier may be applied as one of 2, 3, and 4, Most preferably, it may be more desirable to apply 2), let's say that the review problems are correct and incorrect as shown in Figure 8. In other words, let's say that when the user is reviewing a specific study completion problem, each time a review problem is provided, repeated review is performed depending on whether the user answers correctly or incorrectly, as shown in FIG. 8.

At this time, whenever a review problem is provided, the review control unit 12 determines whether each provided review problem is a problem provided again in a few days from a previously provided review problem (i.e., for each review problem, how many days does the review problem last? Review questions can be provided by displaying primary information about whether the questions will be provided again later (the 10th feature of this app).

Referring to FIG. 8, for example, in the case of a review problem that comes at D+31, since it is a review problem that comes 16 days after D+15, the review control unit 12 provides the first review problem when providing a review problem at D+31. Review problems can be provided by displaying information such as “Day 16” or “Day 16 Challenge” in the first area of the review problem.

According to the tenth feature of this app, which provides review problems with primary information displayed, the device 10 provides primary information to the user (learner) about how soon the current review problem will be. It can be displayed. Accordingly, the device 10 can enable the user to check (recognize) whether the user (learner) answered the question correctly several days ago when he or she answers the review question correctly, and feels a sense of accomplishment accordingly. You can have it.

For example, if a review problem was provided 1000 days ago, the user uses primary information (e.g. information such as 'This review problem is the 1000th day challenge problem') to confirm that the review problem provided this time was provided 1000 days ago. (recognition) will be possible. This device 10 provides a review problem containing primary information, so that the user (learner) who solves the review problem can develop a sense of challenge to solve the given review problem by using the primary information, and if the user actually If you get the correct answer to a given review question, it can give you a great sense of accomplishment.

This device 10 maximizes the learning effect for languages of various countries (i.e., Korean, foreign languages (e.g., English, Japanese, etc.)) by providing a language learning method having the first to tenth features described above. You can do it. In particular, the present device 10 can maximize the effect of language learning for sentences by providing a learning technology focusing on sentences longer than words, rather than simple word learning. At this time, among the first to tenth features in the device 10, for example, the fourth feature, the sixth feature, and the eighth feature may not be used simultaneously. That is, in the case of the fourth feature, the sixth feature, and the eighth feature, in the present device 10, only one of these features can be selectively applied and used, and the selection of the feature to be applied is, for example, performed using the present device 10. Choices/decisions can be made by the user (learner).

This device (10) most naturally induces regular and steady learning and repetition, which are the most important elements in language learning, and in the case of repeated learning (i.e., in the case of repeated review of learned problems), it provides the largest amount of memory compared to the minimum input. We can provide effective language learning/review in a way that is effective.

The method in which the 3 problems (i.e., today's problem) provided every day in this device 10 are learned is as shown in FIG. 2: “Problem solving process (step 1) to solve today's problem → correct answer confirmation process (2 Learning can be accomplished through “step) → review process (step 3) → confirmation process (step 4).”

Additionally, the manner in which a particular problem is reviewed in the device 10 may be as follows. First, review of a specific problem (i.e., provision of review problems) is, for example, 'D+1, D+3, D+7, D+15, D+30, D+60, D+120, Review can be done on dates corresponding to D+210, D+365, D+600, and D+1000. For example, the review date and number of times may be changeable by the user. Second, Q1 problems on a certain day may be reviewed before Q1 problems on the day on which they are reviewed, and similarly, Q2 on a certain day may be reviewed before Q2 on the day on which they are reviewed. However, problems that have not been learned by the device 10 (i.e., unfinished problems that have not been studied) may not be reviewed or re-learned.

For example, if Q1 on the 3rd day is completed, the review questions for the completed questions (Q1 on the 3rd day) are before Q1 on the 4th day, before Q1 on the 6th day, before Q1 on the 10th day, before Q1 on the 18th day, and before Q1 on the 33rd day. , can be provided before Q1 on day 63, before Q1 on day 123, before Q1 on day 213, before Q1 on day 368, before Q1 on day 1003.

In addition, as an example, the review problem that appears before Q2 (problem of the day) on the 17th day is the Q2 review problem (D-15) on the 2nd day, as shown in Figure 4b, under the assumption that all problems have been studied without omission. It can be the same as ‘10th day Q2 review question (D-7) → 14th day Q2 review question (D-3) → 16th day Q2 review question (D-1)’, and all 4 review questions must be completed for review on day 17. Q2, Problem of the Day, may be provided.

Below, we will briefly look at the operation flow of the present application based on the details described above.

The language learning method shown in FIG. 9 can be performed by the device 10 described above. Therefore, even if the content is omitted below, the content described with respect to the device 10 can be equally applied to the description of the language learning method.

Referring to FIG. 9, in step S11, the providing unit may provide today's problem for language learning.

At this time, the problem of the day includes a plurality of problems provided multiple times at a preset time, and the provider provides the problem of the day every day, but may provide a new problem of the day every day.

Additionally, in step S11, when providing today's problem, if there is a review problem provided by the same-day review control unit, the provision unit may provide today's problem after providing the review problem provided on that day.

Next, in step S12, the review control unit may consider whether the user has completed learning of today's problem provided in step S11 and provide a review problem for reviewing the problem that has been studied.

At this time, in step S12, the review control unit may delete an unfinished problem for which learning has not been confirmed by the user among a plurality of problems in today's problem so that re-learning and review are not possible.

In addition, in step S12, in the case of a study completion problem for which learning has been confirmed by the user among a plurality of problems in today's problem, the review control unit provides preset review period information to enable review, and responds to the study completion problem. Review questions can be provided according to the review cycle within the preset review period information.

Here, the review cycle may be information about the cycle between a plurality of review days set for a plurality of review days. Additionally, the review cycle may be adjusted differently each time a review question is provided, depending on whether the user answers the provided review question correctly.

In the above description, steps S11 and S12 may be further divided into additional steps or combined into fewer steps, depending on the implementation of the present disclosure. Additionally, some steps may be omitted or the order between steps may be changed as needed.

The language learning method according to an embodiment of the present application may be implemented in the form of program instructions that can be executed through various computer means and recorded on a computer-readable medium. The computer-readable medium may include program instructions, data files, data structures, etc., singly or in combination. Program instructions recorded on the medium may be specially designed and constructed for the present invention or may be known and usable by those skilled in the art of computer software.
