The question section 143a adjusts the difficulty level by changing the question format by selecting a combination of English sentence, voice, picture, translation, spelling input, or selection input. The questions given in this embodiment are words or sentences related to language learning, and the question format of each question includes a combination of the original sentence, voice, picture, translation, spelling input or selective input of each question.

In addition, the question database included in the learning support database 35c classifies and accumulates each question by genre, and the question unit 143a displays the questions of the corresponding genre according to the genre selected by the learner's operation. Read from the problem database and ask questions.

The answer acquisition unit 143b is a module that acquires the answer input by the learner for the question given. The determination unit 143c is a module that compares the answer acquired by the answer acquisition unit 143b with the answer stored in the question database of the learning support database 35c, and determines the correctness of the acquired answer.

The re-question setting unit 143d is a module that sets the question interval and the difficulty level from the last question to the next re-question date and time based on the judgment result information and the question time information for each question. , The default value of the question interval until re-questioning for each question is held for each question count and question format, and it also has a function to expand and contract the default value question interval based on the learner's correct / incorrect judgment for the question. There is. The questioning unit 143a has a function of executing the re-questioning of the question to the learner based on the re-questioning condition determined by the questioning condition determining unit 143e. Further, the re-question setting unit 143d also has a function of setting the questions accumulated in the master problem storage unit of the learning support database 35c to be re-questioned at a predetermined cycle.

The question condition determination unit 143e is a module that determines the date and time for re-questioning the question for the learner and the re-question condition, which is the question format, based on the question interval and the difficulty level set by the re-question setting unit 143d.

The result of the event processing executed by the event control unit 143 (progress of learning support, correctness judgment of the quiz, victory / defeat of the mini game, score, etc.) is notified to the learning support progress processing unit 141 on the learning support server 3 side. It is accumulated in various databases 35a to 35c and reflected in the subsequent learning support progress processing.

(Operation of learning support system)
By operating the learning support system described above, the learning support method of the present invention can be implemented. FIG. 4 is a flow chart showing the operation of the learning support system. The processing procedure described below is only an example, and each processing may be changed as much as possible. Further, with respect to the processing procedure described below, steps can be omitted, replaced and added as appropriate according to the embodiment.

As shown in FIG. 4, first, the learning support application is started on the smartphone 1 to start learning (S201). At this time, the current learning history or scenario data is referred to on the application, the current learning level of the learner and the progress of the quiz game are read, and the game starts as a continuation from the previous end point. When learning is started, scenario data is referred to as the learning support progresses, and after the last question set based on the judgment result information and question time information for each question included in the learning history is given. The question interval and difficulty level until the next re-question date and time are acquired. Next, the re-questioning conditions based on the acquired questioning interval and difficulty level are determined (S202). Further, at this time, the start condition is confirmed, and when the start condition is not satisfied (“N” in S203), the application is terminated through step S211 (“Y] in S211).

When the start condition is satisfied (“Y” in S203), the event processing to be generated is set by referring to the scenario data, and the top screen as shown in FIG. 5 is displayed. On this top screen, information info1 such as the current learning level and selection button group Btn1 are displayed together with the moderator character Ca1, and the learner taps any of the selection button group Btn1 to perform a game mode or other optional mode. Is selected (S204). These modes may be determined automatically based on scenario data as well as by the learner's selection operation. For example, the movie and the explanation and report by the moderator character Ca1 are automatically started as an optional mode according to the progress of learning support, and the game mode is appropriately started when a predetermined story branch point on the scenario data is reached. ..

When the game mode is selected (“game mode” in S203), the screen transitions to the quiz scene screen as shown in FIG. 6 and the game mode is executed (S207). Questions related to language learning are given in quiz format for the questions given on this quiz scene screen, and the question format for each question is English (original) Q2, voice, image (picture) Q1, Japanese translation (Japanese translation). Translation) Q3, the answer method is selection of the selection input button Bt2, vocalization, spelling input, etc., and is composed of a combination of these questions and the answer method. At this time, the learner can select a favorite genre for the question to be asked.

In the vocalization problem, the accuracy of pronunciation by the learner is evaluated based on the control signal generated by the voice recognition processing unit 144 according to the control by the scenario control unit 142, and the correctness judgment of the answer is executed according to the evaluation. .. More specifically, the answer acquisition unit 143b acquires the answer selected or uttered by the learner for the question, and the judgment unit 143c acquires the answer acquired by the answer acquisition unit 143b and for learning support. The correctness of the acquired answer is determined by comparing with the answer stored in the question database of the database 35c (S208). In this correctness judgment, as the judgment result information, the learning support progress processing unit 36 as the learning history recording unit sets the date and time when the question was answered together with the question format when the question was asked for each question and for each learner. It is associated with the question time information shown and recorded as learning history information in the learning support database 35c (S209). In addition, for the rewards acquired by this learning, for example, on the learning end screen as shown in FIG. 7, the total amount of acquisitions at that time is displayed as acquisition point information info4, and the breakdown for each problem (word) learned as information info3. And learning level are displayed together with the moderator character Ca1.

On the other hand, when the option mode is selected in step S203 (“option mode” in S204), the option mode is executed (S205), and the character is operated according to the event processing generated according to the scenario data. And execute various optional functions (S206).

Then, the learning history information is updated and a report is created (S209) according to the correctness determination (S208) during the game mode execution and the event processing (S206) during the option mode execution, and the scenario proceeds (S210). ). Each of the above-mentioned processes S202 to 210 is repeated until the application ends (“Y” in S211) (“N” in S211).

(Details about each process)
Details of each process executed in the flow described above will be described below.
(1) Structure of question questions The question database included in the above-mentioned learning support database 35c stores basic information of problematic words, learning information of words for determining question format and question date, and words being learned. It consists of a question box to ask.

In addition, the words to be learned have the following characteristics.
・ All 5000 words. Select from words learned in elementary and junior high school to Eiken Level 1 level.
・ Exclude articles such as “a” and “the” and interrogative words that should be learned as part of the phrase from the questions, and let them study together with the phrase in another corner.
・ Words whose meaning is difficult to understand by themselves are given as part of the phrase. At that time, the picture as a hint may also be linked with the phrase to make an image that helps understanding the word.

The basic information of the above words includes the following information for all words.
・ Spelling of English words ・ Pictures that convey the meaning ・ Voice of the model ・ Furigana of Japanese and Kanji ・ Incorrect choices in the four choices (prepared for English, Japanese, and pictures)
・ Genre ・ Difficulty

Of these basic information, regarding the word genre, each problem (word) is classified by genre and stored in the problem database so that the user can select the genre of the word to be learned. In other words, the problem database is categorized so that learners can enjoy learning English words, and naturally learns the meanings (Japanese and pictures), sounds, and spellings (spellings) of words. .. Specific genres include meals / directions / decorative words / movements / body / favorite things / schools / homes / speakers, listeners / vehicles / counting methods / countries and places / life / buildings / hours / people / arts / conversations / State / Appearance / Occupation / Creatures / Units / Town / Nature / Let's convey feelings / Cooking / Sports / Fashion / Shopping / Business etc.

The learning history information for each word is information about the learner's learning proficiency level and question level for each word, and includes the following information.
(a) Proficiency level This is a real value that goes up and down each time the learner answers the question correctly or incorrectly, and the value is changed as follows.
-The initial and minimum proficiency levels are "0" and do not drop below this value.
・ If you answer the question correctly, your proficiency will increase, and if you make a mistake, your proficiency will decrease.
・ By multiplying the time limit digestion rate (30% range in the latter half) for each quiz question, if you answer correctly quickly, your proficiency level will increase significantly, and if you make a mistake early, your proficiency level will decrease slightly. On the other hand, if you answer correctly late, your proficiency level will increase slightly, and if you make a mistake late, it will decrease significantly. The time limit for each quiz question is displayed as, for example, the time limit gauge G1 on the quiz scene screen shown in FIG. 6, and the time limit is notified by the length of the gauge.
-There are settings for the "maximum addition value" of the proficiency level when the answer is correct and the "maximum decrease value" when the answer is incorrect, and the "maximum addition value" of the proficiency level can be optimized for each learner. Ideally, if you continue to answer correctly 5/10/15 ..., it is highly likely that you already understand the words in this level band, and the maximum addition value of proficiency will increase by a certain percentage. ..
・ The learner must answer correctly in the maximum difficulty question format for each study course, so if the proficiency level exceeds the minimum proficiency required for the maximum difficulty question format in the study course by adding the correct answers, It is set to the minimum proficiency level required for the maximum difficulty question format.
・ Of the question levels, it is not suitable to skip as a learning process, and set compulsory questions that the learner must experience at least once.
・ Once the proficiency level exceeds the maximum proficiency level of the question format of the maximum difficulty level of each course, it will not drop below that value.

(b) Question level A value calculated from the proficiency level, which is an integer value of the proficiency level, and the question format is determined from this value.

(c) Last question date This is the last question date.

(d) Review level A value that indicates the progress of the review. The question interval is determined for each level, and the next question date is determined. For example, at levels 0 and 2, the question interval (the number of days elapsed from the last question date) is 3 days or more, level 3 is 12 days or more, and level 4 is 69 days or more. If the learner answers the question correctly, the level is raised by one, and if the learner answers incorrectly, the level is lowered by one. However, the level does not drop below 1. In the present embodiment, the re-question setting unit 143d holds the default value of the question interval until the re-question for each question for each number of questions and for each question format, and defaults based on the learner's correct / incorrect judgment for the question. Increase or decrease the question interval of the value. The width of expansion and contraction of the question interval may be adjusted as appropriate by taking statistics on the correct answer rate of the learner himself and the correct answer rate of other learners, and by processing such as deep learning.

(e) Number of questions The number of questions for a word.

(f) Number of correct answers The number of correct answers for a word.

(g) Status The word transitions through five statuses in order as shown below.

(2) Question box The question box is an aggregate for storing words being learned. In the present embodiment, there are the following types, and the number of stored words is set according to the proficiency level.
・ "Reading title Box"
The proficiency level is less than 0-8 and the number of stored items is 7 to 20.
・ "Writing question Box"
The proficiency level is less than 8-13 and the number of stored items is 10 to 20.
・ Review question box The proficiency level is 13 or higher, the review level is 0 to 4, and the number of stored items is unlimited.

(4) Question format The question format is determined from the question level that reflects the learning status of the words included in the learning history information. A blacklist is provided for each word so that homonyms and confusing incorrect answer options are not given in the answer, and the question section 143a controls the question by referring to this blacklist when generating the question and excluding the corresponding question. .. For example, the question unit 143a executes blacklist reference and generation control of incorrect answer options at the time of questioning so that the homonyms and confusing incorrect answer options are not included in the button Btn2 shown in FIG.

In addition, essential questions must be passed by the word master, and even after the proficiency level has declined.
The contents of the question format are as shown in the table below.

The notes in Tables 2 and 3 above are as follows.
* 0 Hide the first half of the English spelling. If it is not divisible, it is masked by truncating the integer or less (example: in the case of 5 characters, 2 mask characters + 3 text characters). In the case of the answer column, you will be asked to enter the spelling of the hidden part.
* 0-2 Hide the characters in the second half of the English spelling. If it is not divisible, it is rounded up to an integer or less and masked (example: in the case of 5 characters, 2 text characters + 3 mask characters). In the case of the answer column, you will be asked to enter the spelling of the hidden part.
* 1 Hide some characters (1 character or more and 50% or less) of English spelling. At that time, the first character is always hidden. In the case of the answer column, you will be asked to enter the spelling of the hidden part.
* 2 Image options consist of the following configurations.
・ 1 image of the correct answer ・ 0 to 1 image that appears with the question word This image has a pair or similar relationship with the question word ・ 2 to 3 fake images (however, words that do not correspond to the NG list associated with the question word Limited to)
For the fake image, select "Image in question box".
If the image in the question box is empty, select from the mastered words.
If all the words selected above are NG, select a random word.
* 3 Emphasize one character of the question text that should be entered in green.
* 4 In the future, another spell learning mode (especially voice input) will be supported.

(5) Question screen The following elements are appropriately displayed on the question screen (Fig. 6) viewed by the learner.
・ Moderator character Ca1
・ Display of nth question / 10 (the value of n varies depending on how many questions are being answered) Info2
・ English Q2 of words according to the question level
・ Japanese translation Q3 associated with words according to the question level
・ Voice playback button Btn3 according to the question level
・ Time limit gauge G1
・ Image Q1 associated with words according to the question level
・ Part of speech associated with words ・ Question level ・ Proficiency gauge ・ Answer option button Btn2 according to question level

(6) Time limit for answering Answers must be answered within the time limit, and if the time limit is exceeded, the answer will be incorrect. The time differs depending on the answer method, and the time limit for "four-choice answer" is 20 seconds, and the time limit for "spelling input answer" is the number of characters required for input x 5 seconds.

(7) Reward Points are given to the learner as a reward according to the number of correct answers for each course, and the learner can check the cumulative total of points earned on the day.
As a reward for the "reading course", the number of correct answers x 10 points will be given to the 1st to 7th questions, and twice the total points up to the previous correct answer will be given after the 8th question. If you do not challenge the double points challenge, you can get the points as it is, and if you try the double points challenge and fail, you can get half of the points so far.
On the other hand, as a reward for the "writing course", the number of correct answers x 20 points is given to the 1st to 7th questions, and twice the total points up to the previous correct answer are given after the 8th question.

Note that "probability fluctuation" may be prepared as a reward-giving effect. In this "probability fluctuation" production, while playing the reading course / writing course, as a sudden event, "The next problem is double the points!" Or "If you answer all the questions correctly to the next mug, your heart will be consumed for 30 minutes. "No!" Or, by increasing the entertainingness, the motivation to learn may be continued, or the pressure to the correct answer may be increased.

Furthermore, "Reward for Hall of Fame Words" is provided as a special effect of rewarding. This "hall of fame word" is a word accumulated by extracting the questions that have been correctly answered a predetermined number of times from the learning history information by the master question storage unit and grouping them. This "hall of fame word reward" is a reward for each reading course / writing course when a word becomes "hall of fame", and is given to words that have reached a certain level of proficiency or higher. ..

(8) Upper limit of the number of plays Since points can be obtained infinitely, an upper limit may be set for the number of plays per day. The more you play, the more points you can get, and there is no upper limit. In addition, a difference may be set in the upper limit of the number of plays between a free member and a premium member. The upper limit of the number of plays may be determined as a start condition in step S203 shown in FIG.

As an effect of setting an upper limit on the number of plays, a limit may be set on the appearance time of the moderator character. For example, a gauge indicating the satisfaction level of the moderator character such as "Good night gauge" is provided to provide a learning game. Each time you play, one gauge will be accumulated, and when it reaches a certain value, the moderator character will start to fall asleep. At this time, event processing for extending the time, such as a gauge chance problem, may appear irregularly (probability 1/2) in the final problem of the point double challenge during the learning challenge. If you answer this gauge chance problem correctly, the "good night gauge" will not increase, so you will be able to challenge continuously and the playable time will be extended. When the gauge reaches a certain value, even if you try to play more than that, a message such as "It is not good to overload!" May be output to stop the play.

(9) Event As another production, an event may be planned in which learners compete with each other for the number of master words within the limited distribution period through the Internet 2. For example, the number of master words is totaled for each learner and ranked within the period. In addition, a dedicated blog may be set up to announce the ranking status every week.

In addition, the current situation may be notified to the user every day in the application. The information to be transmitted to the learner includes, for example, the current ranking of oneself, the current number of master words of oneself, the number of master words of a user one higher than oneself at the time of this aggregation, and a reward. In addition, in order to maintain the motivation to continue learning, the learner who has played at least once within a predetermined period may be given the following reward.
・ Reward for higher ranks ・ Reward by lottery ・ Participation reward

(10) Learning Report In the present embodiment, a report distribution unit 38 is provided as a report function in order to maintain the learner's learning motivation and the parent's billing motivation. According to the learning report by this report function, the learner can grasp the learning situation, the expected value for the learning result and future growth, the weak point, the passing of the Eiken examination, the difference from the learning line by grade, the degree of achievement, etc. By presenting, we aim to create, maintain and improve motivation for learning. By letting the learner understand the weak points in an easy-to-understand manner, it is possible to encourage voluntary review. In addition, communication between parents and children can be activated by having the parents confirm the learner's achievements and presenting information that the parents can praise the learner and create a mindset.

The learning report provides information such as the number of words mastered by the learner himself, and lets him / her understand the learning outcomes and weak points. It is more detailed than in the application for parents and adult learners themselves by e-mail. To be able to receive various learning reports. This report email may be limited to premium member (flat-rate) users.

In addition, the learner can check his / her progress status by the report function in the application as shown in FIGS. 8 and 9. The learner can display and view the learning report contents as one of the optional modes by pressing the "learning report" button from the top screen in the application.

The contents of the report include the number and list of mastered words or weak words according to the question format such as listening, reading, writing, etc. as the learning results so far, daily learning diary, vocabulary info5 (Fig. 8), etc. You can include your current level of learning achievement (Eiken grade, grade, etc.). By selecting and instructing each word in the list of this report, the learner can view the English sentence, Japanese translation, illustration, and voice of the word as detailed information info6 of the word as shown in FIG. can do.

The above e-mail format report provides parents or learners with information such as the progress of learning. The content of this report is such that the moderator character acts as a manager to report and give advice, and the text is changed according to the number of mastered words so that parent-child communication occurs. Is preferable. For example, in reporting the number of mastered words, in addition to the report function in the above application, comparison with the number of words mastered at the time of the previous report transmission, and the maximum number of words mastered in one day so far can be described. Allow parents to send messages to learners so that learners can see messages from parents within the application.

In addition, the reporting capabilities inside and outside these applications are designed to provide a "future level" that is based on the rate of progress of learning to date and is expected to be achieved when learning at that rate. May be good. For example, depending on the expected future achievement level, along with guidance on paces such as "I'm in good shape", "I'm terribly fast", and "I'm steadily progressing", "If you study at this pace, one year later You can include a message such as "Master the XX word and aim for the △△△ grade level / Eiken ○ grade!"

(Action / effect)
As described above, according to the present embodiment, it is possible to maintain the learner's learning motivation and improve the retention rate and the correct answer rate by appropriately changing the re-questioning interval and the questioning format in the iterative learning. That is, according to this embodiment, while solving problems related to words one after another in a quiz format, English words can be naturally memorized, and English word learning that each learner can enjoy and learn is realized. A mechanism that allows learners who have never learned English in earnest to naturally learn the meaning (Japanese and pictures), sounds, and spelling (spelling) of words while playing with game-like content. Therefore, it is possible to realize learning English words that can be learned efficiently.
