Description

[Technical Field]

[0001] The present invention relates to a learning support device, a learning support method, and a learning support program that are used in educational settings, qualification examinations, and the like. [Background technology]

[0002] BACKGROUND ART In recent years, information processing devices such as personal computers (PCs), tablet devices, and smartphones have come to be used in learning and examination situations. For example, there is a type of test called CBT (Computer Based Testing) that evaluates the knowledge and academic ability (level of understanding) of test takers based on the scoring results of a test in which the test taker operates an information processing terminal to answer questions. In CBT, test questions are displayed on the display screen of the information processing terminal operated by the test taker. The test taker enters their answers in the answer field for each test question displayed on the display screen of the information processing terminal. The test taker's level of understanding is estimated based on the scoring results of the test taker's answers.

[0003] For example, Patent Document 1 discloses a learning support device that estimates the level of understanding of each examinee using not only the test score but also information such as the time it took to answer questions and the order in which they answered. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-152782 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the above-mentioned conventional learning support device has the following problems. In other words, the learning support device disclosed in the above publication counts the number of stumbling blocks when answering a question based on changes in the answer input speed (number of strokes per unit time), and uses the counted number of stumbling blocks to estimate the user's level of understanding. However, with such learning support devices, it is not possible to fully analyze the user's confusion based solely on the input speed at the time of answering, and there is a risk that it will not be possible to provide effective learning support to each individual user.

[0006] In particular, when estimating a user's level of understanding, only an estimate is made for the level of understanding of incorrect answers, and even if the answer is correct, it is not possible to estimate whether the user has reached a sufficient level of understanding. An object of the present invention is to provide a learning support device, a learning support method, and a learning support program that are capable of providing more effective learning support to each user than ever before. [Means for solving the problem]

[0007] A learning support device according to a first aspect of the present invention is a learning support device applied to a system that has a user operate an information processing terminal to input answers to questions, and includes an answer acquisition unit, a scoring unit, an operation history information acquisition unit, and an understanding level estimation unit. The answer acquisition unit acquires answers to questions. The scoring unit performs scoring based on the answers acquired by the answer acquisition unit. The operation history information acquisition unit acquires history information of operations input by the user into the information processing terminal when answering the questions. The understanding level estimation unit estimates the user's level of understanding for each question that is scored as correct by the scoring unit, based on the user's operation history information acquired by the operation history information acquisition unit.

[0008] Here, for example, in educational settings, entrance exams, qualification exams, etc., answers entered by users are graded using information processing terminals such as tablet devices, smartphones, and PCs (Personal Computers), and for questions graded as correct, operation history information leading up to the final answer is obtained to estimate each user's level of understanding. Here, the questions displayed on the information processing terminal may be questions that can be answered by inputting characters, or questions that can be answered by selecting an option.

[0009] The operation history information includes, for example, writing history information including the transitions in writing answers, information on the time required to write answers, and the like. As a result, even if the final answer is correct, if the user hesitates to answer and ends up with the correct answer by chance, it is possible to estimate whether the user's level of understanding is sufficient or insufficient by inferring the user's hesitation based on the operation history information. As a result, for example, by providing appropriate advice even for questions for which the answer was correct, it is possible to provide more effective learning support tailored to each individual user than before.

[0010] A learning support device according to a second aspect of the present invention is a learning support device according to the first aspect of the present invention, wherein the understanding level estimation unit estimates the user's understanding of the question in accordance with changes in the answer content contained in the operation history information acquired by the operation history information acquisition unit. As a result, when the user is unsure about the answer but gives the final answer, the transition of the answer content can be used as a reference to guess the user's hesitation when answering and estimate the user's level of understanding.

[0011] A learning support device according to a third aspect of the present invention is a learning support device according to the first or second aspect of the present invention, wherein the understanding level estimation unit estimates the user's understanding of the question based on the answer time included in the operation history information acquired by the operation history information acquisition unit.

[0012] Here, the answer time may be recorded, for example, as the time from when the user selects the question and it is displayed until the user inputs the answer, or it may be recorded as the time while the cursor on the display screen moves within the range of the question. As a result, if the user is unsure about the answer but gives a final answer, the time it took to give the answer can be used as a reference to estimate the user's hesitation when giving the answer and the user's level of understanding.

[0013] The learning support device according to the fourth aspect of the present invention is the learning support device according to the first or second aspect of the present invention, and further includes an advice generation unit that generates advice to be used in providing learning guidance to the user based on the changes in the content of the user's answers contained in the operation history information acquired by the operation history information acquisition unit and the level of understanding for each question estimated by the understanding level estimation unit. This makes it possible to generate appropriate advice according to the level of understanding based on the results of the above-described understanding level estimation and present it to the user.

[0014] A learning support device according to a fifth aspect of the present invention is the learning support device according to the first or second aspect of the present invention, wherein the understanding level estimation unit sets the estimation result of the understanding level for each question in stages. This allows the user's level of understanding to be set in stages, for example, by taking into consideration the changes in the content of the user's answers and the time it took to answer, such as (a) a correct answer without hesitation, (b) a correct answer with some hesitation, (c) an incorrect answer after hesitating between the correct answer and the correct answer, or (d) an incorrect answer without hesitation.

[0015] A learning support device according to a sixth aspect of the present invention is the learning support device according to the fourth aspect of the present invention, wherein the understanding level estimation unit sets an estimation result of the understanding level for each question in stages, and the advice generation unit generates advice corresponding to the estimation result set in stages. This allows the system to generate advice that corresponds to the user's level of understanding, which is set in stages, such as (a) the correct answer without hesitation, (b) the correct answer after some hesitation, (c) the wrong answer after hesitating between the correct answer and the correct answer, and (d) the wrong answer without hesitation, thereby providing appropriate advice according to the user's level of understanding.

[0016] A learning support device according to a seventh aspect of the present invention is a learning support device according to the first or second aspect of the present invention, wherein the operation history information includes input information from an input device that inputs characters and symbols into a text box on a browser. By using the input information of characters and symbols entered into the text box as operation history information, it is possible to infer the user's hesitation when answering and estimate the user's level of understanding of the correct answer.

[0017] A learning assistance device according to an eighth aspect of the present invention is a learning assistance device according to the first or second aspect of the present invention, wherein the operation history information includes operation information by an operation device that moves a cursor displayed on a display screen of an information processing terminal.

[0018] A learning assistance device according to a ninth aspect of the present invention is the learning assistance device according to the first or second aspect of the present invention, wherein the operation history information includes an answer that has been input multiple times for one question. This allows the contents of the answers entered multiple times before the final correct answer is entered to be used as operation history information, thereby making it possible to infer the user's hesitation when answering and estimate the user's level of understanding of the correct answer.

[0019] A learning support device pertaining to a tenth aspect of the present invention is the learning support device pertaining to the first or second aspect of the present invention, further comprising a storage unit that stores operation history information for each question. As a result, by having a memory unit that stores operation history information for each question entered by the user, the user's level of understanding of the correct answer can be estimated by extracting the operation history information stored in the memory unit.

[0020] A learning support method according to an eleventh aspect of the present invention is a learning support method executed by a learning support device applied to a system that has a user operate an information processing terminal to input answers to questions, and includes an answer acquisition step, a scoring step, an operation history information acquisition step, and an understanding level estimation step. In the answer acquisition step, an answer acquisition unit of the learning support device acquires answers to questions. In the scoring step, a scoring unit of the learning support device scores the answers based on the answers acquired by the answer acquisition unit. In the operation history information acquisition step, the operation history information acquisition unit of the learning support device acquires history information of operations input by the user to the information processing terminal when answering the questions. In the understanding level estimation step, the understanding level estimation unit of the learning support device estimates the user's level of understanding for each question scored as correct by the scoring unit based on the user's operation history information acquired by the operation history information acquisition unit.

[0021] Here, for example, in educational settings, entrance exams, qualification exams, etc., answers entered by users are graded using information processing terminals such as tablet devices, smartphones, and PCs (Personal Computers), and for questions graded as correct, operation history information leading up to the final answer is obtained to estimate each user's level of understanding. Here, the questions displayed on the information processing terminal may be questions that can be answered by inputting characters, or questions that can be answered by selecting an option.

[0022] The operation history information includes, for example, writing history information including the transitions in writing answers, information on the time required to write answers, and the like. As a result, even if the final answer is correct, if the user hesitates to answer and ends up with the correct answer by chance, it is possible to estimate whether the user's level of understanding is sufficient or insufficient by inferring the user's hesitation based on the operation history information. As a result, for example, by providing appropriate advice even for questions for which the answer was correct, it is possible to provide more effective learning support tailored to each individual user than before.

[0023] A twelfth aspect of the present invention provides a learning assistance program loaded into a learning assistance device applied to a system that allows a user to operate an information processing terminal to input answers to questions, the learning assistance program causing a computer to execute a learning assistance method including an answer acquisition step, a scoring step, an operation history information acquisition step, and an understanding level estimation step. In the answer acquisition step, an answer acquisition unit of the learning assistance device acquires answers to questions.

In the operation history information acquisition step, the operation history information acquisition unit of the learning assistance device acquires history information of operations input by the user into the information processing terminal when answering the questions. In the understanding level estimation step, the understanding level estimation unit of the learning assistance device estimates the user's level of understanding for each question scored as correct by the scoring unit, based on the user's operation history information acquired by the operation history information acquisition unit.

[0024] Here, for example, in educational settings, entrance exams, qualification exams, etc., answers entered by users are graded using information processing terminals such as tablet devices, smartphones, and PCs (Personal Computers), and for questions graded as correct, operation history information leading up to the final answer is obtained to estimate each user's level of understanding. Here, the questions displayed on the information processing terminal may be questions that can be answered by inputting characters, or questions that can be answered by selecting an option.

[0025] The operation history information includes, for example, writing history information including the transitions in writing answers, information on the time required to write answers, and the like. As a result, even if the final answer is correct, if the user hesitates to answer and ends up with the correct answer by chance, it is possible to estimate whether the user's level of understanding is sufficient or insufficient by inferring the user's hesitation based on the operation history information.

[0026] As a result, for example, by providing appropriate advice even for questions for which the answer was correct, it is possible to provide more effective learning support tailored to each individual user than before. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0029] A learning support device according to one embodiment of the present invention will be described below with reference to FIGS. In the present embodiment, more detailed explanation than necessary may be omitted. For example, detailed explanation of well-known matters or redundant explanation of substantially the same configuration may be omitted. This is to avoid unnecessary redundancy in the following explanation and to facilitate understanding by those skilled in the art. Furthermore, the applicant provides the accompanying drawings and the following description to enable those skilled in the art to fully understand the present invention, and they are not intended to limit the subject matter described in the claims.

[0030] (1) Configuration of the learning support system including the learning support device 10 The learning support device 10 of this embodiment is included in a server device 1 that constitutes a network system for conducting tests using the CBT (Computer Based Testing) method shown in Figure 1, for example, in educational settings, entrance exams, qualification exams, etc.

[0031] The server device 1 is connected to a plurality of tablet terminals 2 connected via the Internet 3. As shown in FIG. 2, the server device 1 includes a learning support device 10, a question DB (Data Base) 17, and a communication unit 18. The learning support device 10 grades answers entered by a user using a tablet terminal 2 such as a tablet terminal or a smartphone. The detailed configuration of the learning support device 10 will be described later.

[0032] The question DB 17 stores question data, along with the correct answer (model answer) and standard answer time for each question, in association with each other. The information stored in the question DB 17, such as the question, correct answer, and standard answer time, is transmitted to multiple tablet terminals 2 via the communication unit 18 and the Internet 3. The communication unit 18 transmits information such as questions to multiple tablet terminals 2 via the Internet 3, and also receives information such as the content of the answer for each question, operation history information at the time of answering, and answer time from the multiple tablet terminals 2 via the Internet 3.

[0033] For example, in an educational setting, a plurality of tablet terminals 2 are provided to each student, and questions are displayed on a display screen 2a (see FIG. 4, etc.) and the students input their answers to the displayed questions. The tablet terminals 2 also display test questions distributed from the server device 1 via the Internet 3 on the display screen. The currently selected question is displayed on the display screen 2a of the tablet terminal 2. For example, when question 1 is selected on the tablet terminal 2, question 1 is displayed on the display screen 2a of the tablet terminal 2. When question 2 is selected on the tablet terminal 2, question 2 is displayed on the display screen 2a of the tablet terminal 2.

[0034] The tablet terminal 2 switches the questions displayed on the display screen 2a in response to an operation on the selection tab 2b displayed on the display screen 2a. In other words, the user operates the selection tab 2b to display a desired question (for example, questions 1 to 5) on the display screen 2a of the tablet terminal 2. The tablet terminal 2 generates, for example, a history of the user's input operations (character input, cursor operation, etc.) during the test time (the period from the start to the end of the test) as operation history information.

[0035] The operation history information is an accumulation of input operation information during the test, and includes, for example, input information from an input device that inputs characters and symbols into a text box on a browser, and operation information from an operation device that moves a cursor displayed on the display screen 2a of the tablet terminal 2. The operation history information also includes input information of answers that have been entered multiple times for one question.

[0036] Then, when the test time is over, the tablet device 2 transmits to the server device 1 the answers to each question (the character strings entered in the answer column for each question at the end of the test) and the operation history information generated during the test time. As shown in FIG. 3, the tablet terminal 2 includes a control unit 20, a touch panel (input device) 21, and a communication unit 22.

[0037] The control unit 20 controls the operations of each unit of the main body of the tablet terminal 2, and also has an answer acquisition unit 20a and an operation history information generation unit 20b. For example, at the end of a test, the answer acquiring unit 20a acquires the character string entered in the answer column of a question as the user's answer information for that question. The operation history information generating unit 20b generates operation history information that accumulates operation information of input operations performed by the user via the touch panel 21. The operation information includes an operation code that identifies the input operation by the user and the operation time when the user performed the input operation. The input operations performed by the user include an operation of inputting characters into the answer field of a question, an operation of deleting characters entered in the answer field, an operation of moving the cursor displayed on the display screen 2a of the tablet terminal 2, an operation of selecting a question displayed on the display screen 2a, etc.

[0038] The touch panel (input device) 21 displays test questions distributed from the server device 1, and displays answers to questions entered by the user. The touch panel 21 also receives answers entered by the user using, for example, a touch pen, a finger, or the like. The communication unit 22 is provided in each tablet terminal 2 and performs data communication with the server device 1 via the Internet 3.

[0039] (2) Configuration of the learning support device 10 The learning support device 10 of this embodiment is provided within a server device 1, as shown in Figure 2, and receives and scores the user's answers to each question, the transitions leading up to the answer, the answering time, etc., entered into multiple tablet terminals 2, and estimates the user's level of understanding for each question. More specifically, as shown in FIG. 2, the learning support device 10 includes an answer log receiving unit (answer acquisition unit) 11, a scoring unit 12, an operation history information acquisition unit 13, an understanding level estimation unit 14, a log data storage unit (storage unit) 15, and an advice generation unit 16.

[0040] The answer log receiving unit (answer acquisition unit) 11 acquires, via a communication unit 18 connected to the Internet 3, information on the answers to each question entered by the user into the tablet terminal 2 and the changes in characters, etc. entered until the final answer is reached. The marking unit 12 compares the answers acquired by the answer log receiving unit 11 with the correct answers for each question stored in the question DB 17 to determine whether the answers are correct or incorrect, and performs marking.

[0041] The operation history information acquiring unit 13 acquires, from the answer log data acquired by the answer log receiving unit 11, information on the final answer and the transition leading up to the final answer. Here, the operation history information is, for example, accumulated information such as input information from an input device that inputs characters, symbols, etc. into a text box on a browser, and operation information from a touch panel that moves a cursor displayed on the display screen 2a of the tablet terminal 2.

[0042] The understanding level estimation unit 14 estimates the user's level of understanding for each question based on the operation history information acquired by the operation history information acquisition unit 13, not only for questions that were scored by the scoring unit 12 and were answered incorrectly, but also for questions that were answered correctly. Specifically, the understanding level estimation unit 14 estimates the user's level of understanding of the question based on at least one of the changes in answer content and the length of answer time contained in the operation history information acquired by the operation history information acquisition unit 13.

[0043] More specifically, the understanding level estimation unit 14 not only determines that the answer to a question that was answered incorrectly is of insufficient understanding (understanding level C), but also estimates that the answer to a question that was answered correctly is of a possible insufficient understanding (understanding level B) or of a sufficient understanding (understanding level A) based on information such as the change in the answer at the time of answering and the time required to answer, depending on whether the answer was entered immediately or after some hesitation.

[0044] The log data storage unit 15 stores the log data of the answers acquired by the answer log receiving unit 11 (final answers, answer transitions, answer times, etc.). The answer time stored in the log data storage unit 15 is recorded as the time from when the user selects the question selection tab 2b and the question is displayed on the display screen 2a of the tablet terminal 2 until the user inputs the answer.

[0045] The advice generation unit 16 generates advice to be used in providing study guidance to the user based on the transition of the user's answer content included in the operation history information acquired by the operation history information acquisition unit 13 and the level of understanding for each question estimated by the understanding level estimation unit 14. More specifically, based on the estimation result by the understanding level estimation unit 14, a message including advice regarding the direction of future study, etc. is generated according to the level of understanding estimated in stages (for example, three levels of understanding A, B, and C). The message generated by the advice generation unit 16 is transmitted to the tablet terminal 2 for each user via the communication unit 18.

[0046] This allows users who have taken a test to view their results to not only check the marking results (score) and questions that were answered incorrectly, but also to view messages containing useful advice for future study to deepen their understanding, even for questions that were answered correctly but were deemed to be insufficient in understanding.

[0047] <Examples of display based on questions and comprehension estimation results> In the learning support system including the learning support device 10 of this embodiment, for example, English questions are displayed as shown in FIG. In the example shown in Figure 4, Question 1 asks you to choose the most appropriate word from (a), (b), or (c) to fill in the underlined part of the English sentence, "I _____ a book last night." Then, if the operation history information indicates that the user's answer was the correct answer (a) read and that the user entered it without hesitation, the understanding level estimation unit 14 estimates the understanding level to be A, and as shown in Figure 5, the advice generation unit 16 generates supplementary information such as "This time, read is an irregular verb, so read here is in the past tense," along with the message "Great!", and displays this on the display screen 2a of the tablet terminal 2.

[0048] Next, based on the operation history information, if the user's answer is (a) read, which is the correct answer, but the user hesitates between other answers or takes longer than the average standard answer time to answer, the comprehension level estimation unit 14 estimates the comprehension level as B because there is a possibility that the user's understanding is insufficient even if the final answer is correct, and as shown in Figure 6, the advice generation unit 16 generates the following message along with the message, "Your answer is correct, but you should review English tenses and accurately understand the usage and conjugation of each word." Below is a basic explanation of the present tense and past tense. 1. Present tense ... 2. Past tense Supplementary information such as "..." is generated and displayed on the display screen 2 a of the tablet terminal 2 .

[0049] Next, based on the operation history information, if the user's answer is (b) or (c) other than the correct answer (a) read, the understanding level estimation unit 14 estimates that the answer is incorrect and the understanding is insufficient, resulting in an understanding level of C. As shown in FIG. 7, the advice generation unit 16 Along with the message "Incorrect." "The phrase "last night" tells us that this sentence is describing an event that occurred in the past. The words in the options (read, reads, reading) are all verbs that mean "to read," but each expresses a different tense." Supplementary information such as this is generated and displayed on the display screen 2a of the tablet device 2.

[0050] <Learning support methods> The learning assistance device 10 of this embodiment carries out the learning assistance method in accordance with the flowcharts of FIGS. Here, the processing in the tablet terminal 2 will be described with reference to FIG. That is, as shown in FIG. 8, in step S11, it is determined whether or not a test has started, and if a test has started, the process proceeds to step S12.

[0051] Next, in step S12, since the test has started in step S11, an initial screen is displayed on the display screen 2a of each tablet terminal 2. Note that the initial screen may be, for example, a screen that displays question 1, or a screen that displays only selection tab 2b for selecting a question.

[0052] Next, in step S13, it is determined whether or not the user has performed an operation input on the display screen 2a on which the initial screen is displayed. If an operation input has been performed, the process proceeds to step S14, and if not, the process proceeds to step S15. Next, in step S14, if the operated character key is a character key or a delete key, the character string in the answer column is edited according to the operated character key.

[0053] Next, in step S15, since it is determined in step S13 that no operation input has been made, it is determined whether or not a question selection operation has been made. If a question selection operation has been made, the process proceeds to step S16, and if no question selection operation has been made, the process proceeds to step S18. Next, in step S16, since it is determined in step S15 that a question selection operation has been performed, the question selected by the user is displayed on the display screen 2a of the tablet terminal 2.

[0054] Next, in step S17, since the character string was edited in the answer field in step S14, or the selected question was displayed on the display screen 2a of the tablet terminal 2 in step S16, operation information including an operation code indicating the content of the user's input operation this time and the time when this input operation was performed is added to the operation history information. The tablet terminal 2 stores the operation history information in a memory included in the control unit 20. Furthermore, the tablet terminal 2 stores, for each question in the test, the character string entered in the answer column for that question in a memory included in the control unit 20.

[0055] Next, in step S18, it is determined whether or not the test end time has arrived. If the test end time has arrived, the process proceeds to step S19, and the processes from step S13 to step S17 are repeated until the test end time has arrived. Next, in step S19, when the time for the test to end in step S18 arrives, the answers to each question and operation history information stored in the memory of the control unit 20 of the tablet terminal 2 are transmitted to the server device 1, and this process ends.

[0056] Next, the processing on the server device 1 (learning support device 10) side will be described with reference to FIG. That is, in step S21, the answer log receiving unit 11 of the learning support device 10 waits until it receives, via the communication unit 18, from the tablet terminal 2 the test questions, answers, and operation history information for the test time.

[0057] Next, in step S22, the operation history information acquiring unit 13 of the learning support device 10 acquires information relating to the transition of the answer status from the answer log acquired by the answer log receiving unit 11. Here, the information regarding the transition of the answer status acquired by the operation history information acquisition unit 13 includes, for example, information on whether or not other answers were entered before the final answer was reached, whether the answer time was longer than the average standard answer time, etc.

[0058] Next, in step S23, the marking unit 12 of the learning support device 10 marks the user's answers for each question in the test. Next, in step S24, the understanding level estimation unit 14 of the learning support device 10 acquires the scoring results and correct / incorrect results of the answers to each question. Next, in step S25, the understanding level estimation unit 14 of the learning support device 10 estimates the user's understanding level in stages for each test question using the scoring results from the scoring unit 12 (step S23), the changes in the user's answer content for that question, the answer time, and the standard answer time (step S22).

[0059] Next, in step S26, the advice generation unit 16 of the learning support device 10 generates a learning guidance message for the user based on the changes in the user's answering status acquired in step S22 and the level of understanding of each question estimated in step S24. Next, in step S27, it is determined whether the understanding level has been estimated for all questions. If it is determined that the understanding level has been estimated for all questions, the process ends. If it is determined that there are questions for which the understanding level has not yet been estimated, the process returns to step S21 and the following process is repeated.

[0060] Next, the details of the understanding level estimation process in step S25 will be described with reference to FIG. That is, in step S31, the understanding level estimation unit 14 of the learning support device 10 determines whether or not an intermediate answer has been input before the final answer, using the operation history information at the time of answering acquired by the operation history information acquisition unit 13. If an intermediate answer has been input, the process proceeds to step S32; if only the final answer has not been input and no intermediate answers have been input, the process proceeds to step S35.

[0061] Next, in step S32, since it is determined in step S31 that an intermediate answer exists, the understanding level estimation unit 14 acquires the content of the intermediate answer and the result of whether it is correct or incorrect. Next, in step S33, the understanding level estimation unit 14 determines whether the intermediate answer was incorrect. If the intermediate answer was incorrect, the process proceeds to step S34, and if the intermediate answer was correct, the process proceeds to step S41.

[0062] If there are multiple intermediate answers, the processes from step S32 to step S34 are carried out for each intermediate answer. Next, in step S34, since it was determined in step S33 that the intermediate answer was incorrect, the understanding level estimation unit 14 analyzes the details of the deviation between the intermediate answer and the correct answer. Next, in step S35, under the assumption that there was an intermediate answer and it was incorrect, the understanding level estimation unit 14 acquires the content of the final answer and its correctness.

[0063] Next, in step S36, the understanding level estimation unit 14 determines whether the final answer is incorrect. If the final answer is incorrect, the process proceeds to step S37. If the final answer is correct, the process proceeds to step S42. Next, in step S37, since both the intermediate answers and the final answer were determined to be incorrect in steps S33 and S36, the understanding level estimation unit 14 determines the understanding level to be C and analyzes the discrepancy between the final answer and the correct answer.

[0064] Next, in step S38, the operation history information acquiring unit 13 acquires the transition of the content of each answer (intermediate answer and final answer). Next, in step S39, the understanding level estimation unit 14 analyzes the content of each answer (intermediate answer and final answer) and the deviation from the correct answer. Next, in step S40, the advice generating unit 16 points out in a guidance format any points where there is a possibility of insufficient understanding, generates advice appropriate for learning guidance to be displayed on the tablet terminal 2, and ends the process.

[0065] On the other hand, in step S41, since it was determined in step S33 that the intermediate answer was correct, and the correct answer was once entered, the understanding level estimation unit 14 determines that the understanding level is B, and in step S40, advice corresponding to understanding level B to be displayed on the tablet terminal 2 is generated, and the processing ends. Next, in step S42, since it was determined in step S36 that the final answer was correct, it is determined whether there were any intermediate answers. Here, if the final answer is correct and there were no intermediate answers, the process proceeds to step S44.

[0066] On the other hand, in step S43, although the final answer was correct in steps S36 and S42, it was determined that there were intermediate answers, so there is a possibility that understanding is insufficient and the understanding level is determined to be B. In step S40, advice corresponding to understanding level B (for example, Figure 6) is generated to be displayed on the tablet terminal 2, and the process ends. On the other hand, in step S44, if the final answer in step S42 is correct and there are no intermediate answers, it is assumed that the correct answer was entered without hesitation, so the understanding level estimation unit 14 determines that the understanding level is A, and in step S40, advice corresponding to understanding level A (for example, Figure 5) to be displayed on the tablet terminal 2 is generated, and the processing ends.

[0067] <Major features> The learning support device 10 of this embodiment is a device applied to a system in which a user operates an information processing terminal to input answers to questions, and includes an answer log receiving unit 11, a scoring unit 12, an operation history information acquiring unit 13, and an understanding level estimation unit 14. The answer log receiving unit 11 acquires answers to questions. The scoring unit 12 performs scoring based on the answers acquired by the answer log receiving unit 11. The operation history information acquiring unit 13 acquires history information of operations input by the user to the information processing terminal when answering the questions. The understanding level estimation unit 14 estimates the user's level of understanding for each question that has been scored as correct by the scoring unit 12, based on the scoring results of the user's answers for each question and the user's operation history information acquired by the operation history information acquiring unit 13.

[0068] As a result, even if the final answer is correct, if the user hesitates to answer and ends up with the correct answer by chance, it is possible to estimate whether the user's level of understanding is sufficient or insufficient by inferring the user's hesitation based on the operation history information. As a result, for example, by providing appropriate advice even for questions for which the answer was correct, it is possible to provide more effective learning support tailored to each individual user than before.

[0069] [Other embodiments] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention. (A) In the above embodiment, the present invention has been described as being implemented as a learning assistance device and a learning assistance method, but the present invention is not limited to this.

[0070] For example, the present invention may be realized as a learning support program that causes a computer to execute the above-described learning support method. This learning assistance program is stored in a memory (storage unit) installed in the learning assistance device, and a CPU reads the learning assistance program stored in the memory and causes the hardware to execute each step. More specifically, the CPU reads the learning assistance program and executes the answer acquisition step, the grading step, the operation history information acquisition step, and the understanding level estimation step, thereby achieving the same effects as those described above. The present invention may also be realized as a recording medium on which a learning assistance program is stored.

[0071] (B) In the above embodiment, an example has been described in which a server device 1 connected to a plurality of tablet terminals 2 via the Internet 3 estimates a user's level of understanding for each question from the content of the answer entered into each tablet terminal 2, the time required to answer, etc. However, the present invention is not limited to this. For example, the estimation of the user's level of understanding may be provided on each tablet device, rather than on the server device side. In other words, the learning support device may be provided inside each tablet device, rather than on the server device.

[0072] (C) In the above embodiment, an example has been described in which the understanding level estimation unit 14 of the learning support device 10 estimates the understanding level in stages according to the scoring results of the user's answers, changes in the content of the answers, the answering time, etc. However, the present invention is not limited to this. For example, if the answer is correct, but only if there is a suspicion of hesitation when answering, it may be assumed that the understanding is insufficient, and a message containing useful advice for the user may be generated and displayed on a tablet device or the like.

[0073] (D) In the above embodiment, an example has been described in which a user's answer to an English question is input to the tablet terminal 2. However, the present invention is not limited to this. For example, the configuration may be such that answers to tests and quizzes in subjects such as mathematics, science, social studies, and Japanese are input into an information processing device such as a tablet terminal.

[0074] (E) In the above embodiment, an example has been described in which the tablet terminal 2 is used as the information processing terminal into which the user inputs answers, but the present invention is not limited to this. For example, the answers to the questions may be input into another information processing terminal such as a PC (Personal Computer) or a smartphone.
