This is the same and will not be described. In short, the terminal 2 has the same configuration as that of the server device 1 except for the storage unit 25. The storage unit 25 is a storage unit that stores data referred to by the control unit 21 and is, for example, a hard disk.

<B: Operation>
Next, the operation of this embodiment will be described.
<B-1: Lecture group generation operation>
FIG. 9 is a flowchart showing the flow of a lecture group generation process performed by the server device 1. The server device 1 executes the lecture group generation process at a predetermined timing (for example, every month, every week, etc.). The timing for executing the lecture group generation process is not limited to this. For example, the lecture group generation processing may be executed at the timing when the server apparatus 1 receives the request data indicating the inquiry from the student, that is, the inquiry from the terminal 2, It can be appropriately changed according to the design of the server device 1 and the like.

  First, the server device 1 refers to the student database DB4, acquires a student ID, and acquires a course ID indicating a course that the student assigned with the student ID desires to acquire credits. (Step S1). In this operation example, the student ID and the course ID are acquired from the student database DB4. However, the manner of acquiring the student ID and the course ID is not limited to this. For example, the server device 1 The terminal ID and the subject ID may be acquired by receiving the collation request data including the student ID and the subject ID from the terminal 2, and the control unit 11 acquires the subject ID. Anything is acceptable.

  When the student ID and the subject ID are acquired, the control unit 11 reads the lecture element data corresponding to the acquired subject ID from the subject database DB3, and refers to the lecture element database DB2 to indicate at least the read lecture element data. A set of lectures including all lecture elements is generated as a lecture group (step S2).

  Here, an example of specific processing contents of the lecture group generation processing will be described with reference to the drawings. First, the control unit 11 reads out lecture element data corresponding to the acquired subject ID from the subject database DB3. For example, in the example shown in FIG. 5, when the acquired subject ID is “subject 01”, “1-2”, “1-4”, “1-8”, “1-11”, “1” -12 ”are read. Next, the control unit 11 refers to the lecture element database DB2 for each read lecture element, and extracts a lecture including the lecture element for each lecture element.

  FIG. 10 is a diagram illustrating an example of a lecture extracted for each lecture element. In the example shown in the figure, the subjects of which subjects are required to attend five lecture elements “1-2”, “1-4”, “1-8”, “1-11”, “1-12”. An example of the case is shown. In this case, three lectures “a1”, “a3”, and “a9” are extracted as lectures including the lecture element “1-2”. Similarly, two lectures “a1” and “a4” are extracted as lectures including the lecture element “1-4”. Lectures including other lecture elements are similarly extracted. In the present embodiment, the control unit 11 extracts a lecture including the lecture for each lecture element. Instead, the control unit 11 illustrates the correspondence between the lecture element and the lecture including the lecture element, as illustrated in FIG. Such a table may be stored in a predetermined storage area of the storage unit 15 in advance.

  Next, the control unit 11 selects a lecture including the lecture element for each lecture element, and generates a lecture group indicating a set of the selected lectures. For example, in the example shown in FIG. 10, since there are three lectures including the lecture element “1-2”, there are three selection patterns for the lecture including the lecture element “1-2”. Further, since there are two lectures including the lecture element “1-4”, there are two selection patterns for the lecture including the lecture element “1-4”. Similarly, 36 (3 × 2 × 2 × 1 × 3) lecture groups are generated in the example shown in FIG. 10 by selecting a lecture corresponding to the lecture element for each lecture element. .

  FIG. 11 is a diagram illustrating an example of a lecture group generated by the control unit 11. As illustrated in the figure, this table stores items of “group ID” and “lecture” in association with each other. Among these items, the group ID item stores a group ID (identification information) for identifying the lecture group. In the “Lecture” item, a group of lecture identification data included in the lecture group is stored. These lecture groups contain all of the lecture elements that are mandatory for the subject, so students can take a course in any combination of these lecture groups. Can be obtained.

  In the present embodiment, the lecture group is generated by the above-described processing. However, the lecture group generation processing performed by the control unit 11 is not limited to this, and the lecture group may be generated according to another algorithm. It can be appropriately changed according to the design of the device. In short, any processing may be used as long as the control unit 11 refers to the lecture element database DB2 and the subject database DB3 and generates a lecture group for acquiring the unit of the subject.

  Returning to the description of FIG. Next, the server device 1 sorts the generated lecture groups according to a predetermined condition (performs ranking) (step S3). In this embodiment, the server device 1 reads the attendance history data corresponding to the acquired attendee ID from the attendee database DB4, and the “lecture tag” and “instruction method tag” of the lecture identification data included in the read attendance history data. ”Is taken for each tag, and attributes with a large number of students are identified. Next, the control unit 11 refers to the tag of the lecture identification data included in the lecture group, and rearranges the generated lecture group in descending order of the number of lectures that match the specified attribute.

  Next, the control unit 11 notifies the student by transmitting data indicating the ranked lecture groups (hereinafter, “sort data”) to the terminal 2 (step S4). The terminal 2 notifies the student by displaying the ranked lecture groups indicated by the sort data transmitted from the server device 1 on the display device of the information output unit 24.

  FIG. 12 is a diagram illustrating an example of a screen displayed on the display device of the terminal 2. As shown, the display device displays a plurality of lecture groups in the sorted order. By viewing this screen, the student can check which lectures and what combinations can be taken to obtain credits.

  In the screen shown in FIG. 12, the student may be able to operate the information input unit 23 to sort a plurality of lecture groups in order of price or time. In this case, first, the student uses the information input unit 23 to perform an operation for sorting the lecture groups in the order of fees (or time). In this operation, for example, the texts T1 and T2 displayed on the screen G in FIG. 12 may be clicked. When the operation is performed by the student, the information input unit 23 outputs an operation signal corresponding to the operated content, and the control unit 11 charges the lecture group according to the signal supplied from the information input unit 23. Request data indicating sorting in order (or time order) is transmitted to the server apparatus 1. When receiving the request data from the terminal 2, the control unit 11 of the server device 1 calculates the attendance efficiency (fee, time, etc.) for each of the generated lecture groups based on a predetermined algorithm. Specifically, for example, for each of a plurality of lecture groups, the control unit 11 refers to a charge tag (or time tag) of the lecture identification data included in the lecture group and obtains charge (or time) statistics. . Next, the control unit 11 rearranges the lecture groups based on the calculated attendance efficiency. In this embodiment, the control unit 11 rearranges the lecture groups in ascending order (or descending order) of the statistical results. Next, the control unit 11 transmits data indicating the rearranged contents to the terminal 2. The terminal 2 updates the display on the display device according to the data received from the server device 1. Thereby, the list of lecture groups rearranged in order of fee (or time) is displayed on the display device. The student can compare the attendance efficiency of the respective lecture groups by referring to the screen displayed on the display device.

<B-2: Lecture action>
Next, the lecture operation of this system will be described. The student operates his / her terminal to transmit distribution request data including the student ID assigned to him / her and the lecture ID of the lecture he / she wishes to take to the server apparatus 1 via the network 3. When the server apparatus 1 receives the distribution request data from the terminal 2, the server apparatus 1 distributes lecture data representing the lecture indicated by the received distribution request data to the terminal 2. The terminal 2 outputs the lecture data distributed from the server device 1 to the information output unit 24. That is, the terminal 2 emits sound represented by the lecture data from the speaker and displays an image represented by the lecture data on the display device. The student attends the lecture by listening to sound and images emitted from the terminal 2.

  When the distribution of the lecture data is finished, the server device 1 registers the lecture identification data indicating the distributed lecture in the student database DB 4 as the attendance history. Thus, every time a lecture is taken, the server device 1 registers lecture identification data indicating the taken lecture in the student database DB 4 in association with the student ID that has received the distribution request. Thereby, the attendance history is accumulated for each attendee in the attendee database DB4.

  By the way, the task of confirming which lectures should be taken in what pattern to acquire credits for a certain subject is more complicated as the number of subjects and lectures increases. Become. On the other hand, in the present embodiment, the server device 1 identifies a lecture group of a lecture necessary for acquiring a unit of a certain subject and notifies the student, so that the student acquires the unit of the subject. Therefore, it is possible to recognize which lectures should be taken.

  In the present embodiment, the server device 1 ranks the lecture groups with reference to the attendance history of the students and informs the students of the results, so that the students can make their own preference. It becomes easy to grasp the lecture group.

  In addition, according to the present embodiment, the server device 1 sorts the lecture groups in the order of the attendance efficiency (the attendance time, the attendance cost, etc.). Can be easily compared.

<C: Modification>
As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, It can implement with another various form. An example is shown below. In addition, you may combine each following aspect suitably.
(1) In the above-described embodiment, the control unit 11 sorts the generated lecture groups according to predetermined conditions and displays them in the sorted order. However, the lecture groups are not necessarily sorted and generated. Lecture groups may be displayed as a list.

  Moreover, not only sorting, but the control unit 11 analyzes the attendance history data for each student, and selects one or more satisfying a predetermined condition from the generated lecture group according to the analysis result, The selected lecture group may be displayed. Specifically, for example, the control unit 11 refers to “lecturer tag” or “teaching method tag” of the lecture identification data included in the attendance history data, collects statistics for each tag, and attends in the attendance history. Identify a large number of attributes. Next, the control unit 11 refers to the tag of the lecture identification data included in the lecture group, and from the generated lecture group, the number of lectures that match the specified attribute satisfies a predetermined condition (for example, lecture 1 or a plurality of lectures are selected in the descending order of the number, and the selected lecture group is transmitted to the terminal 2 to notify the student.

  For example, when a certain student has taken a lot of lectures with a specific lecturer or specific instruction method, the lecturer and the lecture method with the same instruction method are presented to the student. Lectures that suit your taste can be presented.

  In addition, for example, when a certain student has not taken a lecture of a specific item so much, a lecture including the item is presented to the student so that the student is not good at the lecture. To help overcome the weaknesses.

  The mode of selecting the lecture group is not limited to this. For example, the control unit 11 calculates the attendance efficiency based on a predetermined algorithm for each of the generated lecture groups, and calculates the attendance calculated from the generated lecture group. You may make it select the thing in which efficiency satisfy | fills a predetermined condition. Specifically, for example, for each of the generated lecture groups, the control unit 11 refers to the “time tag” (or “fee tag”) of the lecture identification data included in each lecture group, and totals the time ( (Or the total of the charges) may be calculated, and the calculation result satisfying a predetermined condition (for example, the top five in ascending order, the charge is equal to or less than a predetermined amount, etc.) may be selected.

(2) In addition, the mode of selecting the lecture group is not limited to this. For example, the control unit 11 acquires achievement data indicating the degree of achievement of each lecture of the student, and obtains it from the generated lecture group. One or more lecture groups may be selected based on the achieved achievement data. Specifically, for example, the degree of achievement data indicating the level of achievement of the lecture is stored for each lecture in the student database DB4, and the control unit 11 selects one or more lecture groups based on the degree of achievement data stored. Multiple selections may be made. Specifically, for this selection, for example, a lecture group including items with low achievement may be selected. By doing so, it is possible to support the overcoming of the weak items.

  In this case, as an aspect of acquisition of the reachability data, for example, the administrator of the server device 1 may manually input using the information input unit 13 and the reachability data input by the control unit 11 may be acquired. For example, the test may be performed using a network, and the server device 1 may receive the reachability data from the terminal 2. In short, the control unit 11 of the server device 1 acquires the reachability data. Any thing can be used.

(3) Further, in the above-described embodiment, the control unit 11 determines the arrival level of the lectures that have been taken, and for lectures with a low level, shows the lectures effective for review to the students and encourages review. May be. In this case, for example, the degree of achievement data indicating the degree of achievement of the lecture is stored for each lecture in the student database DB4, and the control unit 11 determines the arrival level indicated by the degree of achievement data stored in advance. It is determined whether it is below the threshold value. When there is a lecture in which the achievement level is determined to be less than or equal to the threshold (hereinafter referred to as “unreachable level lecture”), the control unit 11 selects from the lecture group that generated the lecture corresponding to the attribute of the unreachable level lecture. The student may be notified by transmitting data indicating the selection result to the terminal 2.

(4) In the above embodiment, the server device 1 generates a lecture group for one subject, but the number of subjects is not limited to one, and a plurality of subjects may be specified in combination. In this case, for example, the student performs an operation of specifying a plurality of subjects using the information input unit 23 of the terminal 2, and the terminal 2 transmits a subject ID indicating the specified subjects to the server device 1. To do. When the server device 1 receives the subject ID from the terminal 2, the server device 1 specifies a lecture group necessary for acquiring units of a plurality of subjects indicated by the received subject ID with reference to the subject database DB3 and the lecture element database DB2.

  The more subjects and lectures there are, the more complicated the combination of lectures that need to be taken in order to earn credits. It becomes so complicated. On the other hand, according to this aspect, even when the number of subjects that the student wants to take is large, the server device 1 identifies the lecture group to be taken as a lecture group and notifies the student. The student can grasp the lecture group that he / she should take without performing complicated work.

(5) In the above-described embodiment, the control unit 11 generates a set of lectures in which all the lecture elements set in advance for each subject are included as a lecture group. A set of lectures including a part of lecture elements set in advance for each subject may be generated as a lecture group. In this case, for example, a tag indicating the importance of the lecture is assigned to the lecture identification data, and the control unit 11 refers to the assigned tag to extract a lecture element whose importance satisfies a predetermined condition. A group of lectures including the extracted lecture elements may be generated as a lecture group.

(6) In the above-described embodiment, the student is notified by displaying the lecture group on the display device, but the notification mode is not limited thereto, and may be notified by, for example, outputting a voice message. Moreover, the form which transmits the data which show the produced | generated lecture group to an e-mail format to a student's mail terminal may be sufficient. In addition, information indicating the lecture group may be output and stored on a storage medium. In this case, the student can refer to the information by reading the information from the recording medium using a computer. it can. The lecture group may be printed out on a predetermined sheet. In short, any information may be used as long as it outputs information indicating a lecture group so that a message or information can be transmitted to the student by some means.
