DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the same elements are given the same reference numerals and redundant description will be omitted.

[0011] FIG. 1 is a diagram showing the configuration of an online learning system 1 according to this embodiment. As shown in FIG. 1, the online learning system 1 includes a content distribution server (information processing device) 10, an instructor terminal 20, and a student terminal 30. The content distribution server 10 is installed in a management center or the like, and is connected to the instructor terminal 20 and the student terminal 30 via a communication network. The communication network may be, for example, the Internet, a LAN, a telephone line, an in-house network, a mobile communication network, Bluetooth (registered trademark), WiFi (Wireless Fidelity), other communication lines, or a combination thereof, and may be wired or wireless. A plurality of instructor terminals 20 and student terminals 30 may be provided.

[0012] The content distribution server 10 is a general-purpose computer and may be composed of a single computer or multiple computers distributed over a communication network. The content distribution server 10 includes a control device 11 and a storage device 12. The control device 11 includes, as hardware, a CPU, memories such as ROM and RAM, an input interface, an output interface, a communication interface, and buses connecting these. The control device 11 realizes various functions by the CPU executing programs stored in the ROM or the like. The storage device 12 is a hard disk drive or the like.

[0013] 2 is a block diagram showing functional modules realized by the CPU of control device 11 executing a program stored in ROM etc. As shown in Fig. 2, the functional modules include a setting screen display processing unit 111, a distribution setting receiving unit 112, a confirmation content distribution unit 113, a result screen display processing unit 114, an extraction unit 115, a student designation receiving unit 116, and a learning content distribution unit 117.

[0014] The storage device 12 stores a student management table 121 and a content management table 122. The student management table 121 records each student's ID (account information), their past course history, homework completion status, etc. The content management table 122 stores learning content and review content to be distributed.

[0015] The instructor terminal 20 and the student terminal 30 are terminals used by the instructor and the students to use the online learning system 1, respectively, and are terminal devices such as tablet terminals, personal computers (PCs), notebook PCs, smartphones, etc. As shown in FIG. 1, the instructor terminal 20 includes a processor 21, an input device 22, a display device 23, a communication interface 24, and a storage device 25. The student terminal 30 includes a processor 31, an input device 32, a display device 33, a communication interface 34, and a storage device 35. The input devices 22 and 32 are touch panels, keyboards, etc. The display devices 23 and 33 are liquid crystal displays, etc.

[0016] Next, the learning content distribution process performed by the online learning system 1 according to this embodiment will be described with reference to the sequence diagram of FIG. The instructor terminal 20 displays a distribution setting screen for homework (confirmation content) generated by the setting screen display processing unit 111 of the content distribution server 10 (step S101). FIG. 4 is a diagram illustrating an example of the homework distribution setting screen. As shown in FIG. 4, the homework distribution setting screen includes a distribution content display field A1 that displays the lecture to be distributed as homework, a homework distribution destination (student) display field A2, and a homework type selection field A3. Homework types include lecture video followed by confirmation test, confirmation test only, confirmation test followed by lecture video, etc., and the instructor can select the desired homework type using the radio buttons provided in the selection field A3. The homework distribution setting screen also includes an automatic homework follow-up distribution setting field A4.

[0017] The instructor operates the instructor terminal 20 to select the lecture to be distributed and the distribution destination of the homework (step S102). The instructor can select the homework to be distributed by checking the checkbox of the lecture to which the instructor wishes to distribute the homework from among the lectures displayed in the distribution content display field A1 on the homework distribution setting screen shown in FIG. 4. The instructor can also select the students to whom the homework is to be distributed by checking the checkbox of the student to whom the homework is to be distributed from among the students displayed in the distribution destination display field A2. The distribution setting receiving unit 112 of the content distribution server 10 determines the lecture to be distributed and the distribution destination of the homework in accordance with the operation on the instructor terminal 20 (step S103).

[0018] The instructor operates the instructor terminal 20 to set up automatic distribution of lecture videos and confirmation tests (learning content, hereinafter also referred to as follow-up assignments) for homework follow-up (step S104). The instructor can set whether to enable automatic distribution (yes / no) by selecting either radio button a41 or a42 in the automatic distribution setting field A4 provided on the homework distribution setting screen shown in Fig. 4.

[0019] When the "Automatically distribute (Yes)" radio button a41 for follow-up assignments is selected, a condition input box A5 is displayed on the homework distribution setting screen shown in Figure 4. By inputting conditions into the condition input box A5, such as the percentage of correct answers for homework completed by students (0% to 50% in Figure 4), the instructor can set in advance the extraction conditions for students to whom follow-up assignments will be automatically distributed.

[0020] In this embodiment, the type of content delivered in follow-up is different from the type of homework described above and is preset to, for example, only a set of lecture video and confirmation test. However, in the case of automatic delivery of follow-up, as with homework, the instructor may be able to select the type of content from a set of lecture video and confirmation test, confirmation test only, confirmation test with explanatory video, etc. In the latter case, when the radio button a41 for automatic delivery is selected, a selection field for the type of follow-up content may be displayed on the homework delivery setting screen.

[0021] The distribution setting reception unit 112 of the content distribution server 10 sets automatic distribution of follow-up assignments (whether to distribute or not and extraction conditions for distribution targets) in response to an operation on the instructor terminal 20 (step S105).

[0022] When the instructor performs an operation to distribute the homework on the instructor terminal 20 (step S106), the confirmation content distribution unit 113 of the content distribution server 10 distributes the homework data to the student terminals 30 of the selected students (step S107).

[0023] FIG. 5 is a diagram illustrating an example of a home screen displayed on the student terminal 30. FIG. 6 is a diagram illustrating an example of a lecture screen displayed on the student terminal 30. Students can check the content of the distributed homework by looking at the distribution content display field D1 on the home screen shown in FIG. 5. After students view the lecture video displayed in the video display field D2 on the lecture screen shown in FIG. 6, they can answer the confirmation test by selecting the confirmation test button D3.

[0024] When the student receives the homework, he / she operates the student terminal 30 to answer the homework and submits the answered homework (step S108). When the answered homework is submitted, a grading process is executed in the content distribution server 10, and the grading results (correct answer rate) are registered for each student in the student management table 121 (step S109).

[0025] When automatic delivery of follow-up assignments is set to ON (step S110: Yes), the extraction unit 115 of the content distribution server 10 determines whether there are any students to whom the follow-up assignments are to be automatically delivered based on the set extraction conditions (step S111). For example, when a homework correct answer rate of 0% to 50% is entered in the follow-up condition input box A5 provided on the homework delivery setting screen (step S104, see FIG. 4), the extraction unit 115 extracts students who have a correct answer rate of 0% to less than 50% from among the students who have answered the homework.

[0026] If there are students to whom follow-up assignments are to be automatically distributed (step S111: Yes), the learning content distribution unit 117 distributes follow-up lecture videos and confirmation tests to the student terminals 30 of the extracted students (step S112).

[0027] Here, the extraction unit 115 may determine whether the answer of each student satisfies the extraction conditions each time a homework answer is submitted by the student, and the learning content distribution unit 117 may distribute follow-up assignments at individual times to students whose answers are determined to satisfy the extraction conditions. In this way, by determining whether to automatically distribute a follow-up assignment based on the extraction conditions and distributing the same each time a homework answer is submitted by a student, the student can quickly receive feedback on the homework they have submitted.

[0028] On the other hand, if the follow-up assignment is set to "Do not automatically distribute (No)" (Step S110: No), or if the follow-up assignment is set to "Automatically distribute (Yes)" (Step S110: Yes) but there are no students to whom the assignment is to be automatically distributed (Step S111: No), the result screen display processing unit 114 of the content distribution server 10 causes the instructor terminal 20 to display the homework result screen (Step S113).

[0029] The instructor checks the homework results on the result screen displayed on the instructor terminal 20. FIGS. 7 and 8 are diagrams showing examples of result screens for checking the homework results. FIG. 7 is a screen displaying the overall homework results, and FIG. 8 is a screen displaying the answers to each question included in the homework. The information displayed on the result screen is based on the homework grading results of each student registered in the student management table 121.

[0030] Specifically, Figure 7 shows the number of attempts (P1), the first correct answer rate (P2), and the highest correct answer rate (P3) for each student for a certain homework assignment (in the example in Figure 7, the confirmation test for the first lesson). It also shows the percentage of students who have completed the submission (P4) and the overall average first correct answer rate (P5). For students who have not yet submitted their homework, these fields are left blank.

[0031] Figure 8 shows the average initial correct answer rate for each question (P6), the content of the question and the answer (P7), and the correct / incorrect status of each student (P8). When a question is selected in the left column, the content and answer of the selected question are displayed in the upper right column, and the correct / incorrect status of each student is displayed in the lower right column.

[0032] The number of attempts (P1) indicates the number of times each student has submitted the homework. The displayed color may be changed depending on the number of attempts. The initial correct answer rate (P2) is the correct answer rate when each student first submitted the homework. The highest correct answer rate (P3) is the correct answer rate when the correct answer rate was the highest among the results submitted by each student. The display mode (for example, color) may be changed for students whose highest correct answer rate is equal to or exceeds a predetermined correct answer rate, such as 100%.

[0033] The percentage of students who have completed their homework (P4) is the percentage of all students who have submitted their homework at least once. Note that "all students" can refer to students on a class basis, school basis, etc. The overall average first-time correct answer rate (P5) is the average first-time correct answer rate of all students.

[0034] The average first-time correct answer rate for each question (P6) is the average of all students' first-time correct answer rates for each question included in the homework. Question content and answer (P7) shows the content of each question and the correct answer information. Each student's correct / incorrect status (P8) shows each student's most recent correct / incorrect information for each question. Students who have answered correctly at least once are displayed as "correct," and students who have never answered correctly are displayed as "incorrect." If a student has not answered, the field is displayed as blank.

[0035] If the instructor wishes to distribute a follow-up assignment to any of the students displayed on the results screen (step S114: Yes), the instructor can manually select the target students on the results screen (step S115). Specifically, on the results screen shown in FIG. 7, the instructor checks the checkbox C1 of the student to whom the assignment should be distributed. For example, the instructor can select a student whose highest correct answer rate is not 100%. Alternatively, on the results screen for each question shown in FIG. 8, the instructor checks the checkbox C2 of the student to whom the assignment should be distributed. For example, the instructor can select students who answered incorrectly for each question.

[0036] Furthermore, the instructor can extract students who meet certain conditions on the results screen and then select the students to whom the results should be distributed. For example, selecting the condition specification button B1 for the initial correct answer rate on the overall results screen shown in FIG. 7 displays a condition input box, and the instructor enters the student extraction conditions (e.g., an initial correct answer rate of 0% to 50%) in the condition input box. To extract students who have not submitted their homework, the instructor checks the "Include incompletes" box. After entering the conditions and operating the "Refine" button, the extraction unit 115 extracts students who meet the specified extraction conditions and displays them on the results screen. The instructor can reselect students to whom the results should be distributed (by checking the checkbox) from the displayed students, or check the top checkbox C0 to select all displayed students. Similarly, selecting the condition specification button B2 for the highest correct answer rate displays a condition input box, allowing the instructor to extract students based on the highest correct answer rate. Furthermore, on the results screen for each question shown in FIG. 8, selecting the condition specification button B3 for correct / incorrect information and selecting "Incorrect" extracts and displays only students who answered the question incorrectly.

[0037] When the instructor selects the "Distribute homework to selected students" button B4 on the results screen (step S116), the student designation receiving unit 116 accepts the students specified in the check boxes as the distribution targets. Furthermore, the instructor specifies the follow-up assignment (learning content) to be distributed to the selected students on the follow-up distribution setting screen illustrated in FIG. 9. The type of learning content can be selected from a set of lecture video and confirmation test, confirmation test only, confirmation test with explanatory video, etc. Furthermore, necessary information such as the distribution period can be entered. Furthermore, the students to whom the content will be distributed can be confirmed on the follow-up distribution setting screen. When the instructor selects the "Distribute" button B5 (step S117), the learning content distribution unit 117 distributes the follow-up assignment to the student terminals 30 of the students specified as the distribution targets (step S118).

[0038] When the student receives the follow-up assignment, the student operates the student terminal 30 to answer the assignment and submit the answered assignment (step S119). The attendance screen for the follow-up assignment can be configured in the same way as the attendance screen for the homework illustrated in FIG.

[0039] When the solved assignment is submitted, the content distribution server 10 executes a grading process, and the grading results (correct answer rate) are registered for each student in the student management table 121 (step S120). Furthermore, the result screen display processing unit 114 of the content distribution server 10 causes the instructor terminal 20 to display a result screen of the follow-up assignment (step S121).

[0040] Fig. 10 is a diagram illustrating an example of an assignment confirmation screen displayed on the instructor terminal 20. The results screen shown in Fig. 10 displays a list of students to whom follow-up assignments have been automatically or manually distributed, as well as each student's assignment submission status, the number of confirmation tests completed, the degree of mastery of the confirmation tests, the average initial correct answer rate, the date and time of the last assignment, etc. The instructor can check the results of the assignment on the results screen and, if necessary, distribute follow-up content again.

[0041] Note that the results screen shown in Figure 10 may display a list of all students to whom homework was distributed, including students to whom follow-up assignments have not been distributed. In this case, a message such as "No follow-up assignments distributed" may be added to students to whom follow-up assignments have not been distributed, making them easily identifiable.

[0042] As described above, according to this embodiment, in a system that allows online classes, when setting up the distribution of homework (check content), whether or not to automatically distribute follow-up assignments (learning content) is set. If automatic distribution is set to "yes," students who meet the set extraction criteria are extracted based on each student's answers to the check content. If automatic distribution is set to "no" or there are no students eligible for automatic distribution, information including each student's correct answer rate is displayed on the homework result screen, allowing the instructor to manually specify students. As a result, if automatic distribution is set to "yes," follow-up assignments can be automatically distributed to all students who meet the extraction criteria. If automatic distribution is set to "no" or there are no students eligible for automatic distribution, follow-up assignments can be distributed to students designated by the instructor. This allows follow-up assignments to be distributed appropriately and efficiently according to the instructor's situation, such as the instructor's policy and workload.

[0043] Furthermore, according to this embodiment, the homework distribution setting screen allows the user to set whether or not to automatically distribute follow-up assignments and to set the extraction conditions for the students to whom the assignments will be distributed. This allows the system to automatically process everything from the distribution of homework to the distribution of follow-up assignments, improving the instructor's work efficiency.

[0044] Furthermore, according to this embodiment, the selection criteria for students to whom follow-up assignments are to be distributed are set based on the percentage of correct answers to the homework, which allows appropriate distribution of follow-up assignments according to the students' level of understanding.

[0045] Furthermore, in this embodiment, the type of follow-up content can be selected from three types in the case of manual distribution: lecture video followed by a confirmation test, confirmation test only, or confirmation test followed by lecture video, while in the case of automatic distribution, only a set of lecture video and confirmation test is available. This allows the instructor to select an appropriate content type depending on the content of the lecture, etc., in the case of manual distribution, and increases the instructor's convenience because the content type is predetermined in the case of automatic distribution.

[0046] However, even in the case of automatic distribution, it is also possible to allow the user to select the type of follow-up content from the three types mentioned above.In this case, the type of follow-up content can be selected on the homework distribution screen (see Figure 4).

[0047] (Variation) In the above embodiment, the follow-up assignment is distributed either automatically or manually, but both methods may be used in combination. Specifically, even if the follow-up assignment is distributed automatically (see step S112 in FIG. 4), the homework result screen shown in FIGS. 7 and 8 may be displayed on the instructor terminal 20, and the instructor may specify the students to whom the follow-up assignment is to be distributed. In this case, the homework result screen shown in FIGS. 7 and 8 may display information about only the students who are to receive the follow-up assignment automatically. Alternatively, the homework result screen may display information about all students, and for students who are to receive the follow-up assignment automatically, a message such as "Follow-up distributed" may be added.

[0048] This allows follow-up assignments to be uniformly and automatically distributed based on the percentage of correct answers to homework, thereby improving the efficiency of instructors' work, and also allows instructors to manually distribute follow-up assignments at their own discretion, enabling them to provide detailed instruction to students.

[0049] The present invention is not limited to the above-described embodiment, and can be embodied in various other forms without departing from the spirit of the present invention. Therefore, the above-described embodiment is merely an example in all respects and should not be interpreted as being limiting. For example, the order of the above-described processing steps can be arbitrarily changed or executed in parallel as long as no contradiction occurs in the processing content.
