Description

The present invention relates to a technique for providing explanatory information according to a learner's level for a learning problem.

Conventionally, when a learner solves a problem using learning materials or the like, the learner is aware of the difficulty of the problem, that is, the difficulty level, so that the question is provided with a difficulty level (learning level). The answers to the questions are carefully explained so that even learners with a low learning level can understand them.
As such an example, for example, in Patent Document 1, the above knowledge level of the learner is associated with the difficulty level, and a learning exercise is automatically generated based on the learner's learning model and the difficulty level. There is a way to do it.
Further, Patent Document 2 discloses a technique in which correct / incorrect information, answer time information, and attribute information are associated with each question, and the attribute of the next optimum question is determined for each attribute to give a question.

On the other hand, there is also a technology to provide commentary content according to the level of the learner as well as the problem.
As an example of this, in Patent Document 3, the level level of the commentary content provided to the students for each learning unit including "section" or "chapter" is changed based on the history information, and the commentary of the changed level level is changed. It is stated that educational content explained in the content will be provided to the students.

However, in the past, simple answers for scoring and detailed explanations for each question were integrated, and in that case, even simple questions were explained more than necessary, making it difficult for learners to see or answer. There was a problem such as difficulty in finding. In particular, when this answer / explanation book is made into a booklet, there is a problem that the more detailed explanations there are, the thicker the number of pages of the booklet becomes, and the worse the portability becomes.
In particular, if you create a manual for learners of various learning levels, you will have to prepare a lot of explanations for each question, from simple explanations to detailed explanations, and you can make this into a booklet. However, when the list is displayed, the amount of answers and explanations is larger than that of the question collection, and there is a problem that it becomes very difficult to use.

In addition, for students whose learning level is 5 out of 10 levels, learners often inadvertently make mistakes in questions with learning level 3, even if they make a mistake, and even answer them. If you look at it, you can notice where you made a mistake and often do not need much commentary. On the other hand, if you make a mistake in a problem equivalent to your own learning level or a problem with a learning level slightly higher than this (your learning level or level 6 which is a level +1 to this), understand how to solve the problem. In many cases, it is not necessary, and detailed explanations are often required for learners.
However, until now, the answers and explanations have been integrated into a booklet for each question collection, so in many cases, an appropriate amount of explanation is provided to suit each level. Therefore, there is a problem that the commentary is unsatisfactory for the learner with a low learning level, and the commentary is often unnecessarily long for the learner with a high learning level.

Therefore, the present invention has been made to solve the above-mentioned problems, and the booklet of the problem and the information of the answer / explanation are separated, and the detailed explanation information necessary for the learner is required when necessary. Is intended to be provided by.

Hereinafter, the first embodiment according to the present invention will be described with reference to the drawings.
In the present embodiment, the learner solves a question in a question book (booklet), acquires answer information from the answer server 1 via the Internet, and obtains a grade and a commentary on the question.
In the system of the present embodiment, as shown in FIG. 1, the answer server 1 and the learner terminal 2 can be connected via the Internet.
The learner terminal 2 is a terminal used by a learner who learns using a collection of problems. The learner terminal 2 may be a computer such as a so-called personal computer terminal, a mobile phone terminal, or a PDA (Personal Digital Assistance) terminal that can be connected to the Internet and can output the received data to a display or the like.

The answer server 1 is a computer that has the answer to the problem and the explanatory information, and is configured to realize the functions shown in FIG. 2 by executing the computer program stored in the CPU, the hard disk drive, the memory, and the like. Has been done.
The functional block shown in FIG. 2 includes a classroom database (DB) 11, a question / answer database (DB) 12, a communication processing unit 13, a user information processing unit 13, and an answer / commentary processing unit 14.

The classroom database 11 is a database of information on learning classrooms and the like that use texts (booklets) as teaching materials. The classroom database 11 can store information such as a classroom number and a classroom name for identifying a classroom, and information on a text (booklet) adopted by the classroom.

The question / answer database 12 is a database of answers to questions and explanatory information thereof.
As shown in FIG. 3, the question / answer database 12 can store question numbers (No.), simple answers, and detailed answers for each question collection.
The question number is a number for identifying each question, and in this example, the question number further includes information that can identify the grade, subject, text, and number.
The simple answer is the information necessary to score the learner's answer. As this simple answer, for example, it is sufficient that only the information necessary for scoring, such as ○, ×, and the answers “30 °” and “(a)”, is included.
The detailed explanation is a detailed explanation of how to solve the question. It includes the process of thinking leading up to the answer, points on how to solve the problem, hints, and so on. In addition, this detailed explanation may include not only text but also figures, tables, moving images, audio, and the like.
In the question / answer database 12, data such as the number of pages and paragraphs are stored together with the question information of the question collection so that the answers can be displayed for each page according to the layout of the questions in the question collection. You may do it.

The communication processing unit 13 is a processing unit that performs data transmission / reception processing based on a predetermined protocol of the Internet. In the communication processing unit 13, the learner performs data transmission / reception processing with the learner terminal 2.
The classroom information processing unit 14 performs a process of specifying information on teaching materials adopted by the classroom based on the classroom number input by the learner.

The answer / commentary processing unit 15 performs a process of providing answer information and commentary information to the learner terminal 2 in response to a request from the learner.

Next, the flow of processing for providing the learner with the explanatory information according to the present embodiment will be described with reference to FIG.
In FIG. 4, as a premise, the learner who is a user answers the problem collection as shown in FIG.
This collection of questions is provided to the learner in a booklet, and the learner answers in the collection of questions as before.
As shown in FIG. 5, question numbers No. are assigned to each question in this question collection. As mentioned above, the question number is information that can identify the grade, subject, text, and number.

Then, when scoring is performed when the problem is solved, the learner first accesses a predetermined website and inputs the classroom number of the classroom to which he / she belongs on a classroom search screen (not shown) to search. As a result, the classroom information processing unit 13 refers to the classroom database 11 based on the input classroom number, and displays information on the teaching materials adopted by the classroom. Then, the answer / commentary processing unit 15 causes the learner terminal 2 to display the teaching material search screen as shown in FIG. 6 (S1). In response to this, the learner searches for the teaching material by inputting the keyword of the teaching material as the problem-specific information, the series name of the teaching material, and the like.

The answer / commentary processing unit 15 causes the learner terminal 2 to specify the name of the corresponding teaching material (S2).
The screen at this time is shown in FIG. As shown in FIG. 7, a teaching material name 101 corresponding to a keyword or the like, a teaching material level 102, a target grade 103, and a subject 104 are displayed on the screen.

The answer / commentary processing unit 15 causes the learner to display a screen for selecting whether to display a simple answer or a detailed answer (S3).
When the learner selects the simple answer in this state, in the case of the simple answer, the learner is requested to input the number of pages to be displayed (S4).
Then, when the number of pages is input, the answer / commentary processing unit 15 refers to the question / answer database 12, extracts the simple answer of the designated page, and outputs the simple answer to the learner terminal 2 (S5). ..
An example of this is shown in FIG. In the example shown in FIG. 8, in the same image as the text (booklet), only the answer 201 of the question is displayed in red in the answer column. In this way, by displaying only the answer prominently in the answer column of the same image as the text, the learner can understand the relationship between the question and the answer at a glance.
Then, the process may be returned to S3 so that the detailed explanation can be selected.

On the other hand, when the detailed answer is selected in the process of S3, the input of the page range and the stage range or the question number is requested as the question specific information (S11).
Then, based on the input information, the answer / comment processing unit 15 refers to the question / answer database 12, extracts detailed commentary information of the designated question (S12), and outputs this to the learner terminal 2. (S13).
An example of this detailed explanation is shown in FIG. As shown in FIG. 9, in the detailed explanation, explanations such as a detailed solution method and a way of thinking are displayed for each problem.
Then, by looking at the displayed commentary, the learner can fully see and review the commentary only for the specified problem.

As described above, according to the above-described embodiment, only the problems specified by the learner, such as the wrong problem, can be learned by looking at the detailed explanations, so that the learning can be performed very efficiently.
That is, as shown in FIG. 9, only the simple answers are displayed for the questions that the learner does not need, and by displaying the detailed explanations only for the questions that the learner needs, more detailed explanations than necessary are displayed. There are many unnecessary explanations as in the past, so there are no problems such as being difficult to see or rather difficult to understand, and you can learn efficiently.
Also, as a question creator who provides questions, answers, and explanations, if you register simple answers and detailed answers, you can see the information when you need it at the learner's discretion. It is only necessary to register the information of simple answers and detailed explanations without creating multiple patterns of various answers and explanations.

Second Embodiment In the above-described embodiment, there are two types of answers, a simple answer and a detailed answer, but as another embodiment, the detailed answer is divided into the detailed explanation by the above-mentioned characters / charts and the video explanation by the video. , May be selectively provided.
An example of this case is shown in FIG. In the embodiment shown in FIG. 12, the answer / commentary processing unit 15 causes the learner to select one of a simple answer, a detailed answer, and a video commentary in the process of S3 described above.
The explanation selected by the learner is provided.
As a result, even if the learner cannot understand only by the explanation by letters and charts, the explanation by the video can proceed with the learning in the same environment as the actual lecture.

Further, as another providing method, a simple answer, a detailed answer, and a video commentary may be provided step by step.
In this case, the first step is to display the "simple answer" to the learner (1st step), and if you want to see more explanations there, press the "view explanation" button displayed on the screen to "completely complete the answer". Is displayed (2nd step). If you want to deepen your understanding, press the "Watch Video Commentary Class" button displayed on the screen to display the "Video Commentary Class" (3rd step).
In this way, by providing detailed explanations step by step, it is possible to provide solutions that match the learner's understanding step by step.

As yet another method of providing, when the "simple answer" is completed (when the scoring is completed), the two buttons "completely thorough answer" and "video commentary class" are displayed at the same time, from which the learner can see. You may choose the commentary you want.
This allows the learner to see any of the commentary information at his or her own discretion.

Third Embodiment In the above-described embodiment, the detailed explanation is displayed by the learner's selection, but the detailed explanation is displayed only for the problems above the learner's learning level according to the learner's learning level. You may do so.
Here, the learning level represents the difficulty level of the problem. This learning level is determined based on the correct answer rate for each question and the difficulty level determined according to the correct answer rate. In other words, the higher the correct answer rate of the question, the lower the difficulty level, and the lower the correct answer rate, the higher the difficulty level. The correct answer rate and the difficulty level, which are the basis for setting this learning level, may change depending on the time. In other words, for example, around April, there is still a period until the entrance exam, so the correct answer rate is low and the difficulty level is set high for a specific question, but around December, the learning of the entire learner As the number of correct answers increases and the difficulty level decreases, the learning level for a specific problem may be dynamically updated according to the time so as to change to a low level. The setting of the correct answer rate and the learning level (difficulty level) may be the same as the contents of Japanese Patent Application No. 2016-223007 filed earlier by the applicant.
Then, in this embodiment, as shown in FIG. 10, the learning level (level) of each question is stored in the question / answer database 12 for each question in the question collection.

The flow of the process of displaying the detailed explanation in the third embodiment will be described with reference to FIG.
The same process as that of the first embodiment described above will not be described.
In the third embodiment, after the above-mentioned processing of S2, a simple answer is output to the learner terminal (S31).
This allows the learner to score his or her answer.
After that, the learner inputs his / her learning level from the screen (S32).
As a result, when the learner presses the "commentary display" button on the screen, the answer / commentary processing unit 15 refers to the question / answer database 12, and is at the same level as or higher than the learning level entered by the learner. Detailed explanation information is extracted only for the designated problem (S33), and this is output to the learner terminal 2 (S34).
For questions that are easier than the learner's learning level, only simple answers may be displayed, or the display may be omitted.

According to this embodiment, the learner can fully see and review the explanation by seeing the detailed explanation only for the problem that suits his / her learning level.

Further, the detailed answer is displayed not only at the same level as the learner's learning level, but also the detailed answer may be displayed up to the learner's learning level + 1. As a result, it is possible to obtain detailed answers to only problems that are a little difficult for the learner, and to advance their understanding.

Fourth Embodiment In the above-described embodiment, the learner selects and inputs his / her own learning level, but instead of this, a user database is provided and the current learning level information for each learner is stored in advance. In addition, detailed explanations may be provided only for problems that exceed the learner's learning level.
In this case, in order to identify the learner, first input the learner's identification information, thereby acquiring the learner's learning level from the user database, and answering / explaining only the problems above the learning level. The processing unit 15 provides a detailed explanation and / or a video explanation.
As a result, the learner does not have to set the learning level by himself / herself, but learns the problem suitable for his / her learning level according to the learning level set in the user database 11 from the result of the mock test or the like by detailed explanation. It can be performed.
