[0022] The display unit 24A is composed of an LCD (Liquid Crystal Display), an EL (Electro Luminescence) display, or the like, and performs various displays according to display information instructed by the control unit 21A.

[0023] The communication unit 25A includes at least one of a wired communication module such as a NIC and a wireless communication module, and accesses the network 30 to perform electrical communication with external devices.

[0024] The audio input / output unit 26A has an audio input unit such as a microphone, and an audio output unit such as an amplifier and a speaker. The voice input / output unit 26A acquires a voice signal such as a user's voice by the voice input unit, converts it into voice data, and outputs it to the control unit 21A. Furthermore, the audio input / output unit 26A outputs audio through the audio output unit based on audio data input from the control unit 21A.

[0025] The imaging unit 27A is a digital camera unit having an optical system and an imaging element such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). The imaging unit 27A captures an image of a subject (eg, a user), generates image data of a still image or a moving image, and outputs the image data to the control unit 21A.

[0026] [1-4. Description of the configuration of the second terminal device 20B] The second terminal apparatus 20B is a terminal apparatus used by a student. The second terminal device 20B, like the first terminal device 20A, may be any one of a personal computer, a portable terminal device such as a tablet, and a mobile communication device such as a smartphone.

[0030] Operation unit 23B, display unit 24B, communication unit 25B, audio input / output unit 26B, and imaging unit 27B have the same configuration as operation unit 23A, display unit 24A, communication unit 25A, audio input / output unit 26A, and imaging unit 27A, respectively, and therefore their descriptions are omitted.

[0031] [1-5. Explanation of database configuration] FIG. 2 shows an example of the configuration of the database 121. The database 121 is provided in the storage of the memory unit 12 of the server device 10 . The database 121 includes a user management table T1, a study time management table T2, and a question management table T3.

[0032] The user management table T1 is a table for managing information related to users (for example, teachers, students, etc.) who use the information processing services provided by the learning support system 1. The user management table T1 stores information for each user, such as the user ID, user name, email address, user type, class, grade, organization, age, and gender. The user ID is user identification information that is unique identification information corresponding to each user. The user name is identification information that indicates the name of a registered user. The email address is the email address information used by the registered user. User type, class, grade, organization, age, and gender are attribute information corresponding to each user. Of these, user type is attribute information corresponding to the user's status or ability, such as student or teacher, or affiliated institution, department, or field of expertise. Class is information set when the user type is student, and is information on the class to which the user belongs (e.g., class 1, etc.). Grade is information set when the user type is student, and is information on the grade to which the user belongs (e.g., first year, etc.). Organization is information on the organization to which the user belongs (e.g., XXX School).

[0033] The study time management table T2 is a table for managing information related to the study time of the students. The study time management table T2 stores, for each unit, information such as unit information for identifying the unit, the user ID of the user who studied the unit, and study time information for the unit by the user. The unit is a study unit in the teaching material. The unit information is attribute information associated with each page of the learning material that the user uses for studying.

[0034] The question management table T3 is a table for managing information related to questions (test questions) included in a test. The question management table T3 stores question information for identifying a question in association with unit information related to the question. The question management table T3 stores, for each question, correct / incorrect information indicating whether the user's answer to that question is correct or incorrect, and the user ID of that user.

[0035] [2. Description of operation] Next, the learning support function of the learning support system 1 will be described. FIG. 3 is a flowchart showing a flow of an example of using the learning support function.

[0036] (Example of using the learning support function) First, the control unit 11 of the server device 10 records the study time of each unit for each student during a predetermined collection period (step S1). The predetermined collection period is, for example, a period between tests that are periodically conducted.

[0037] Specifically, the control unit 21B of the second terminal apparatus 20B executes the student's learning support application based on an input operation by the student via the operation unit 23B. Next, the control unit 11 of the server device 10 accepts the input operation of the user ID and login by the student via the second terminal device 20B. Next, the control unit 11 accepts the selection operation of the learning material to be studied by the student via the second terminal device 20B. Specifically, the control unit 11 causes the display unit 24B to display the display screen 241 shown in FIG. 4 and accepts the input operation by the student.

[0038] The control unit 11 accepts, via the second terminal device 20B, an operation by the student to select a subject to study from the subject list 241a on the display screen 241. In the example shown in Fig. 4, "Mathematics" is selected. When the control unit 11 receives a selection operation of the subject, it causes the display screen 241 to display a list 241b of teaching materials for the subject selected by the student. The control unit 11 accepts an operation by the student to select a learning material to be studied from the learning material list 241b via the second terminal device 20B. The student selects one learning material to be studied from the multiple learning materials displayed in the learning material list 241b via the operation unit 23B.

[0039] Next, the control unit 11 causes the content of the teaching material selected by the student to be displayed on the display screen 241 of the display unit 24B. FIG. 5 shows an example of displaying teaching material contents 241c showing the contents of the teaching material on the display screen 241. In FIG. In the example shown in FIG. 5, the control unit 11 displays the contents of the teaching material "Mathematics II·B·C Basic" as the teaching material contents 241c on the display screen 241.

[0040] Next, the control unit 11 measures the time during which the student opens the selected teaching material for each page of the teaching material. The time during which the student opens the selected teaching material is the time during which the content of the teaching material selected by the student is displayed on the display screen 241. Next, the control unit 11 stores the measured time as the study time in the study time management table T2 in association with the unit information associated with the page of the teaching material and the user ID of the student who studied. The student who studied is the user who accepted the login.

[0041] The server device 10 may include a means for measuring the time taken by the student to solve the problems written in the selected learning material. In this case, the control unit 11 measures the time taken by the student to solve the problems written in the selected learning material as the study time. Alternatively, the server device 10 may include a means for measuring the time spent by the student writing notes based on the selected learning material. In this case, the control unit 11 measures the time spent by the student writing notes based on the selected learning material as the study time. Alternatively, the control unit 11 may measure the study time as the total time spent while the student has the selected teaching material open, while the student solves the problems written in the selected teaching material, and while the student writes notes based on the selected teaching material.

[0042] Returning to FIG. 3, the control unit 11 administers a test to the students (step S2). Specifically, first, the control unit 11 causes the display unit 24B to display a display screen 241 shown in FIG. Next, the control unit 11 accepts, via the second terminal device 20B, a pressing operation of the test execution button 241d in the display screen 241 by the student. In the example shown in FIG. 6, the test execution button 241d corresponding to the "Final Exam on June 30, 2023" is pressed.

[0043] When the control unit 11 receives a pressing operation of the test execution button 241d, it displays a test content 241e on the display screen 241. The test content 241e includes test questions and answer spaces. Next, the control unit 11 accepts an input operation by the student in the answer column of the test content 241e. The student inputs an answer to the question in the answer column of the test content 241e via the operation unit 23B.

[0044] The test carried out in step S2 is not limited to a periodically conducted academic ability test (midterm exam, final exam, etc.), but may be a short test carried out for each unit.

[0045] In step S2, the test may be conducted using questions printed on paper, in which case the students write their answers to the questions on the paper. In this case, the control unit 11 accepts an input operation of the student's answer by the teacher via the first terminal device 20A.

[0046] 3, the control unit 11 judges whether the answer to the question of the student whose input was accepted in step S2 is correct or incorrect. Next, the control unit 11 stores the judgment result as correct / incorrect information in the question management table T3 in association with the question information and the user ID of the student who answered (step S3).

[0047] In step S2, if the test is conducted using questions printed on paper, the teacher may grade the students' answers written on paper. In this case, in step S3, the control unit 11 accepts an input operation by the teacher of correct / incorrect information on the students' answers, question information, and the user ID of the students via the first terminal device 20A. Next, the control unit 11 associates the input correct / incorrect information, question information, and user ID of the students in the question management table T3.

[0048] Next, the control unit 11 executes the distribution creation process shown in FIG. 7 for each question in the test (step S4).

[0049] (Distribution creation process) First, the control unit 11 refers to the question management table T3 and acquires unit information corresponding to the first target question (step S41). The first target question is a test question and is a target question for which a distribution is to be created in the distribution creation process. Next, the control unit 11 refers to the user IDs and correct / incorrect information stored in the question management table T3, and acquires the user IDs of those who answered the first target question correctly (step S42). The people who answered the first target question correctly may be a group of people in one class who answered the first target question correctly, a group of people in one school year who answered the first target question correctly, or a group of people who answered the first target question correctly among all people who took the test. Next, the control unit 11 refers to the study time management table T2 and acquires the study time linked to the unit information acquired in step S41 and the user ID of each correct answerer acquired in step S42 (step S43).

[0050] Next, the control unit 11 creates a distribution of study times of those who answered correctly for the first target question (correct answer distribution) based on the study times of each of the correct answerers acquired in step S43, and stores it in the storage unit 12 (step S44). The correct answer distribution is a first distribution, which is a distribution of study times of a unit related to the test question for a first group consisting of those who answered the test question correctly. In step S44, the control unit 11 calculates the mean and variance parameters of the normal distribution of the study times of the correct answerers based on the study times of each correct answerer, or creates a distribution of the study times of the correct answerers in the form of a histogram based on the study times of each correct answerer.

[0051] Next, the control unit 11 refers to the user IDs and correct / incorrect information stored in the question management table T3, and acquires the user IDs of those who answered the first target question incorrectly (step S45). When the control unit 11 acquires the user IDs of the group of people in the one class who answered the first target question correctly in step S42, the control unit 11 acquires the user IDs of the group of people in the one class who answered the first target question incorrectly in step S45. When the control unit 11 acquires the user IDs of the group of people in the one school year who answered the first target question correctly in step S42, the control unit 11 acquires the user IDs of the group of people in the one school year who answered the first target question incorrectly in step S45. If in step S42 the control unit 11 acquires the user IDs of the group of people who answered the first target question correctly among all people who took the test, then in step S45 it acquires the user IDs of the group of people who answered the first target question incorrectly among all people who took the test.

[0052] Next, the control unit 11 refers to the study time management table T2, and acquires the study time linked to the unit information acquired in step S41 and the user ID of each incorrect answerer acquired in step S45 (step S46).

[0053] Next, the control unit 11 creates a distribution of study times of the incorrect answerers of the first target question (incorrect answer distribution) based on the study times of the incorrect answerers acquired in step S46, stores it in the storage unit 12 (step S47), and ends the distribution creation process. The incorrect answer distribution is a second distribution that is a distribution of study times of a unit related to the test question for a second group consisting of the incorrect answerers of the test question. In step S47, the control unit 11 calculates the mean and variance parameters of the normal distribution of the study times of the incorrect answerers based on the study times of each incorrect answerer, or creates a distribution of the study times of the incorrect answerers in the form of a histogram based on the study times of each incorrect answerer.

[0054] Returning to FIG. 3, the control unit 11 judges whether or not the correct answer distribution and the incorrect answer distribution for all questions in the test have been created (step S5). If there is a question for which the correct answer distribution and the incorrect answer distribution have not been created (step S5; NO), the control unit 11 returns to step S4 and executes the distribution creation process for the question for which the correct answer distribution and the incorrect answer distribution have not been created.

[0055] On the other hand, when the correct answer distribution and the incorrect answer distribution of all questions have been created (step S5; YES), the control unit 11 executes a distribution display process shown in FIG. 8 (step S6).

[0056] (Distribution display processing) First, the control unit 11 acquires the user ID of the target student (step S61). That is, the control unit 11 acquires user identification information (user ID) for identifying the user. The control unit 11 functions as an acquisition unit. Specifically, the control unit 21B of the second terminal apparatus 20B executes the student's learning support application based on an input operation by the student via the operation unit 23B. Next, the control unit 11 of the server device 10 accepts the input operation of the user ID and login by the student via the second terminal device 20B. The above target students are users who have accepted logins.

[0057] Next, the control unit 11 accepts a selection operation of the second target question by the student via the second terminal device 20B (step S62). The second target question is a test question and is a question for which a distribution is to be displayed in the distribution display process. As described above, for convenience of explanation, in the test questions, the question for which a distribution is created by the distribution creation process is referred to as the first target question, and the question for which a distribution is displayed by the distribution display process is referred to as the second target question. In other words, a test question is a first target question when it is a target for creating a distribution, and a second target question when it is a target for displaying a distribution.

[0058] In step S62, the control unit 11 accepts the selection of a test question. The control unit 11 functions as a reception unit. Specifically, the control unit 11 causes the display unit 24B to display a display screen 241 shown in FIG. Next, the control unit 11 accepts, via the second terminal device 20B, a selection operation of a test for which the student confirms the results from the test result list 241f in the display screen 241. In the example shown in FIG. 9, "Midterm exam on May 20, 2023" is selected. When the control unit 11 receives a test selection operation, it causes the display screen 241 to display the test result 241g of the test selected by the student. 9, the control unit 11 causes the test result 241g to display the test question content, the answer to the question by the target student (you), information indicating whether the answer is correct or not, and the correct answer to the question. The information indicating the correctness of the answer is, for example, a circle mark (correct answer) or a cross mark (incorrect answer).

[0059] The control unit 11 causes the test result 241g to display a distribution display button 241h for displaying the distribution of study times for the units corresponding to the respective questions. The control unit 11 accepts the pressing operation of the distribution display button 241h by the student via the second terminal device 20B. The student presses the distribution display button 241h of the question for which the student wants to see the distribution of the study time via the operation unit 23B. This causes the control unit 11 to accept the selection operation of the second target question by the student.

[0060] Returning to FIG. 8, the control unit 11 refers to the question management table T3 and acquires unit information corresponding to the second target question selected and accepted in step S62 (step S63). Next, the control unit 11 refers to the study time management table T2, and acquires the study time associated with the user ID of the target student and the unit information acquired in step S63 (step S64).

[0061] Next, the control unit 11 refers to the question management table T3 and acquires correct / incorrect information of the second target question linked to the user ID of the target student (step S65). Next, the control unit 11 determines whether or not the answer of the target student to the second target question is correct, based on the correct / incorrect information of the target student to the second target question acquired in step S65 (step S66).

[0062] If the target student's answer to the second target question is correct (step S66; YES), the control unit 11 adds a display showing the study time of the target student for the unit corresponding to the second target question to the correct answer distribution for the second target question created in the distribution creation process (step S67). The distribution of correct answers to the second target question is the distribution of correct answers to the second target question within the class to which the target student belongs, the distribution of correct answers to the second target question within the grade to which the target student belongs, or the distribution of correct answers to the second target question among all people who took the test.

[0063] Next, the control unit 11 causes the display unit 24B to display the correct answer distribution for the second target question to which a display showing the study time of the unit corresponding to the second target question for the target student has been added in step S67, and the incorrect answer distribution for the second target question created in the distribution creation process (step S68), and then terminates the distribution display process. The distribution of incorrect answers to the second target question is the distribution of incorrect answers to the second target question within the class to which the target student belongs, the distribution of incorrect answers to the second target question within the grade to which the target student belongs, or the distribution of incorrect answers to the second target question among all people who took the test.

[0064] As shown in FIG. 9, in step S68, the control unit 11 displays a study time distribution 241i including a correct answer distribution and an incorrect answer distribution below a distribution display button 241h for the second target question on the page. That is, the control unit 11 displays, for each question (test question), a correct answer distribution (first distribution) and an incorrect answer distribution (second distribution) of the second target question, the selection of which is accepted as the accepting unit, in a comparative manner.

[0065] In the example shown in FIG. 9, the control unit 11 displays the learning time distribution 241i with the horizontal axis representing learning time and the vertical axis representing probability density, with the correct answer distribution and the incorrect answer distribution overlapping each other. Moreover, the control unit 11 displays the correct answer distribution and the incorrect answer distribution in the learning time distribution 241i by using different line types. Note that the control unit 11 may display the correct answer distribution and the incorrect answer distribution in the learning time distribution 241i using different colors, markers, or the like. That is, the control unit 11 causes the correct answer distribution (first distribution) and the incorrect answer distribution (second distribution) to be displayed in an overlapping manner in different modes.

[0066] The control unit 11 displays, in the study time distribution 241i, the study time of the unit corresponding to the second target question of the target student added in step S67 with a dashed line. The control unit 11 displays, in the study time distribution 241i, the text “Your study time” indicating that the dashed line is the study time of the unit corresponding to the second target question of the target student. In other words, the control unit 11 displays the correct answer distribution (first distribution) showing the study time of the unit related to the second target question of the target user (target student), who is the user indicated by the user identification information (user ID) acquired by the acquisition unit.

[0067] If the target student's answer to the second target question is correct, the control unit 11 displays the correct answer distribution, a dashed line indicating the target student's study time for the unit corresponding to the second target question, and the words "Your study time" in the same color in study time distribution 241i. In other words, when the target user (target student) answers the second target question correctly, the control unit 11 displays the display (dashed line) indicating the study time of the target user for the unit related to the second target question and the correct answer distribution (first distribution) in the same color. This allows the user to visually confirm that the answer given by the target student to the second target question is correct. The display form of the study time distribution 241i is not limited to the example shown in FIG.

[0068] On the other hand, if the answer of the target student to the second target question is incorrect (step S66; NO), the control unit 11 adds an indication of the target student's study time for the unit corresponding to the second target question to the incorrect answer distribution of the second target question created in the distribution creation process (step S69), and moves the process to step S68. In this case, in step S68, the control unit 11 causes the display unit 24B to display the correct answer distribution of the second target question created in the distribution creation process, and the incorrect answer distribution of the second target question to which the indication of the target student's study time for the unit corresponding to the second target question has been added in step S69. In other words, the control unit 11 displays the incorrect answer distribution (second distribution) showing the study time of the unit related to the second target question of the target user (target student), who is the user indicated by the user identification information (user ID) acquired by the acquisition unit.

[0069] If the answer of the target student to the second target question is incorrect, the control unit 11 displays the study time of the unit corresponding to the second target question of the target student added in step S69 with a dashed line, similar to the study time distribution 241i. The control unit 11 displays the words "Your Study Time" indicating that the displayed dashed line is the study time of the unit corresponding to the second target question of the target student. The control unit 11 displays the correct answer distribution and the incorrect answer distribution with different line types and colors.

[0070] If the target student's answer to the second target question is incorrect, the control unit 11 displays the distribution of incorrect answers, a dashed line indicating the study time of the target student for the unit corresponding to the second target question, and the words "Your study time" in the same color. In other words, when the target user (target student) answers the second target question incorrectly, the control unit 11 displays the display (dashed line) showing the study time of the target user for the unit related to the second target question and the distribution of incorrect answers (second distribution) in the same color. This allows the user to visually see that the target student's answer to the second target question is incorrect.

[0071] By using the above-mentioned study support function, students can compare the study time of those who answered each question correctly and those who answered incorrectly with their own study time.

[0072] 9, the control unit 11 displays the text "Open Study Time Distribution" on the distribution display button 241h of a question that does not display the distribution of study time. On the other hand, the control unit 11 displays the text "Close Study Time Distribution" on the distribution display button 241h of a question that displays the distribution of study time.

[0073] Furthermore, the control unit 11 may display the study time of the target student for the unit corresponding to the second target question in the study time distribution 241i using a line other than the dashed line.

[0074] In addition, in step S68, the control unit 11 may display, in the test result 241g, along with the study time distribution 241i, correct / incorrect information about the second target question of the target student and a comment according to the study time of the target student for the unit corresponding to the second target question. Specifically, a case will be described in which the target student's answer to the second target question is correct and the target student's study time for the unit corresponding to the second target question is longer than a predetermined time. The predetermined time is, for example, the time showing a peak in the distribution of correct answers. In this case, since it is estimated that the target student's learning efficiency is not good, the control unit 11 displays, for example, a comment such as "Try to devise a better study method" on the test result 241g.

[0075] Next, a case will be described in which the target student's answer to the second target question is correct and the time spent by the target student on the unit corresponding to the second target question is less than a predetermined time. The predetermined time is, for example, the time showing a peak in the distribution of correct answers. In this case, since it is estimated that the target student has good learning efficiency, the control unit 11 displays, for example, a comment such as "You're studying efficiently" on the test result 241g.

[0076] Next, a case will be described in which the target student's answer to the second target question is incorrect and the target student's study time for the unit corresponding to the second target question is longer than a predetermined time. The predetermined time is, for example, the time showing a peak in the distribution of correct answers. In this case, since it is estimated that the target student's study method is not good, the control unit 11 displays, for example, a comment such as "Try to devise a better study method" on the test result 241g.

[0077] Next, a case will be described in which the target student's answer to the second target question is incorrect and the target student's study time for the unit corresponding to the second target question is less than a predetermined time. The predetermined time is, for example, the time showing a peak in the distribution of correct answers. In this case, since it is estimated that the target student does not have enough study time, the control unit 11 displays, for example, a comment such as "Please study a little more" on the test result 241g.

[0078] In other words, for each correct and incorrect answer to the second target question by the target student, the control unit 11 displays a comment based on the degree of deviation between the study time at the peak of the correct answer distribution and the study time of the target student for the unit corresponding to the second target question.

[0079] Also, in step S68, the control unit 11 may display the diagrams shown in Figs. 10A to 10C in the test result 241g. Fig. 10A is a diagram showing the study time of the target student for the unit corresponding to the second target question. Figs. 10B and 10C are diagrams comparing the study time of the target student for the unit corresponding to the second target question with the average study time of students in the same class as the target student for the unit corresponding to the second target question. Hereinafter, the average study time of students in the same class as the target student is referred to as the class average.

[0080] In the example shown in FIG. 10A, the control unit 11 displays the study time of the unit corresponding to the second target question of the target student (you) for each predetermined period in May 2023. The predetermined periods are today, this week, and this month.

[0081] In the example shown in Figure 10B, the control unit 11 displays a graph comparing the study time of the target students for the unit corresponding to the second target question from May 1, 2023 to May 7, 2023 with the class average value for the unit corresponding to the second target question. In the example shown in Figure 10B, the control unit 11 may display a graph comparing the study time of the target student for the unit corresponding to the second target question from May 1, 2023 to May 7, 2023 with the average study time of the student who answered correctly and / or incorrectly in the same class as the target student for the unit corresponding to the second target question.

[0082] In the example shown in FIG. 10C, the control unit 11 displays the study time of the target student for the unit corresponding to the second target question in May 2023. Furthermore, the control unit 11 displays the class average value of the unit corresponding to the second target question in May 2023. Furthermore, the control unit 11 displays the average value of the study time of the unit corresponding to the second target question of the correct answerers in the same class as the target student in May 2023. Furthermore, the control unit 11 displays the average value of the study time of the unit corresponding to the second target question of the incorrect answerers in the same class as the target student in May 2023.

[0083] The control unit 11 may display the diagrams shown in FIGS. 11A to 11D in the test result 241g. In the example shown in Fig. 11A, the control unit 11 displays the study time of all units in all subjects of the target student (you) for each predetermined period in May 2023. The predetermined periods are today, this week, and this month.

[0085] In the example shown in FIG. 11C, the control unit 11 displays the cumulative study time of the target student for all units in all subjects, and the cumulative class average value for all units in all subjects. In the example shown in FIG. 11C, the control unit 11 may display the cumulative study time of the target student for all units in a predetermined subject, and the cumulative class average value for all units in the subject. In the example shown in FIG. 11C, the control unit 11 further displays the time when the test was carried out by, for example, a dashed line.

[0086] In the example shown in Fig. 11D, the control unit 11 displays a correlation diagram showing the correlation between the study time of the target student for all units in all subjects in a given collection period and the grades of the target student in all subjects. Furthermore, a correlation diagram showing the correlation between the study time of other students in the target student's class for all units in all subjects in the above collection period and the grades of other students in the target student's class in all subjects is displayed. The grades are, for example, the scores or deviation values ​​of tests held periodically at schools or cram schools. 11D, the control unit 11 may display a correlation diagram showing the correlation between the study time of the target student for all units in a given subject in a given collection period and the grades of the target student in that subject. Furthermore, the control unit 11 may display a correlation diagram showing the correlation between the study time of other students in the target student's class for all units in that subject in the collection period and the grades of the other students in the target student's class in that subject.

The following mainly describes the differences from the above embodiment. The learning support system 1 of this modified example has the same configuration as the learning support system 1 of the above embodiment.

[0088] In distribution display processing step S62 of this modified example, when the control unit 11 accepts a selection operation of a test from the test result list 241f by the student, it displays the test result 241j of the test selected by the student on the display screen 241 as shown in FIG. 12, the control unit 11 causes the test result 241j to display question buttons 241k that display the result of the judgment of whether each question in the test is correct or not with a circle (correct) or a cross (incorrect). Furthermore, the control unit 11 causes the test result 241j to display a score based on the result of the judgment of whether each question is correct or not.

[0089] The control unit 11 accepts the pressing operation of the question button 241k by the student via the second terminal device 20B. The student presses the question button 241k of the question about which the student wants to see details via the operation unit 23B. This causes the control unit 11 to accept the selection operation of the second target question by the student. In the example shown in FIG. 12, "Question 1" is selected.

Next, the control unit 21A accepts a marking operation including a judgment by the teacher as to whether the answer displayed in step A11 is correct or incorrect. Then, the control unit 21A transmits the judgment result as correct / incorrect information to the server device 10 together with the question information and the user ID of the student who answered (step A12).

[0101] Next, the control unit 11 of the server device 10 associates the correct / incorrect information, question information, and the user ID of the student who answered received from the first terminal device 20A, and stores them in the question management table T3 (step A13). Next, the control unit 11 executes the same distribution creation process as in the above embodiment for all questions in the test (step A14).

[0102] Next, the control unit 21A of the first terminal apparatus 20A accepts an operation by the teacher to return the graded test to the student (step A15).

[0103] The control unit 11 of the server device 10 receives the test return from the first terminal device 20A (step A16).

[0104] Next, the control unit 21B of the second terminal apparatus 20B downloads the graded test transmitted by the teacher (step A17).

[0105] Next, the control unit 11 of the server device 10 executes a distribution display process similar to that of the above embodiment (step A18). In step A18, the control unit 21B of the second terminal apparatus 20B accepts a selection operation by the student of a second target question from the graded test.

[0106] Next, the control unit 21B of the second terminal device 20B displays on the display unit 24B the distribution of correct answers to the second target question, the distribution of incorrect answers to the second target question, and the distribution of study time including the study time of the unit corresponding to the second target question for the target student (Step A19), and terminates this process.

This allows students to compare the study time of those who answered each question correctly and incorrectly with their own study time, and to understand whether they spent too much or too little time studying for that question.

[0111] Furthermore, in the learning support device (server device 10) of this embodiment, when the target user (target student) answers the test question (second target question) correctly, the control unit 11 displays the display indicating the study time of the target user for the unit related to the test question and the first distribution (distribution of correct answers) in the same color, and when the target user answers the test question incorrectly, the control unit 11 displays the display indicating the study time of the target user for the unit related to the test question and the second distribution (distribution of incorrect answers) in the same color. This allows the user to visually confirm that the answer of the target student to the second target question is correct, or allows the user to visually confirm that the answer of the target student to the second target question is incorrect.

[0112] Furthermore, in the learning support device (server device 10) according to this embodiment, the control unit 11 displays a comment based on the target user's (target student's) correct or incorrect answer to the test question (second target question) and the degree of deviation between the study time of the peak of the first distribution (distribution of correct answers) and the study time of the target user for the unit related to the test question. This allows students to easily understand whether they are spending enough or too much time studying for the test questions.

[0113] Although the present invention has been specifically described above based on an embodiment thereof, the present invention is not limited to the above embodiment and can be modified without departing from the spirit of the present invention.

[0114] For example, the above-described learning support system can be used even when the first terminal device 20A and the second terminal device 20B are personal computers that are installed in a classroom and cannot be carried around.

[0115] In the above embodiment, the server device 10 functions as a learning support device, but this is not limiting. The first terminal device 20A, the second terminal device 20B, other external devices, etc. may function as a learning support device.
