A multimedia teaching material to be selected is selected from the teaching material storing means 61, and the teaching material selecting means 64 is provided for each student site device via the teacher information transmitting means 62. The student site device 56 includes a teacher information receiving unit 65 that receives the multimedia teaching material from the teacher site device 52, and a student information transmitting unit 56 that transmits the understanding information on the multimedia teaching material to the teacher site device 52. Consists of In the distance learning system A0, a problem exercise is appropriately performed during the distance lecture, and as a result, the student information transmitting means 6
6 (student site device 56 side), based on the answer transmitted to the learning understanding information acquisition means 63 (teacher site device 52 side), the learning understanding status of the student for each student site is grasped in real time on the teacher site device 52 side. Then, an appropriate teaching material is selected for each student site by the teaching material selecting means 64 based on the grasped learning understanding situation, and provided to the student site device 56 by the teacher information transmitting means 62.

[0003]

In the above-described conventional distance learning system A0, both the storage of the teaching materials and the selection processing of the teaching materials for selecting the optimum teaching material for each student are performed on the teacher site device 52. The student site device 56 has only functioned as a mere input / output terminal. However, since the load on the teacher site device 52 is particularly large in the selection process of the teaching material, when the number of student site devices increases, the processing speed for one student site device decreases, and the waiting time on the student site device side increases. And the efficiency is reduced. The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the load on the teacher site device so that the processing efficiency does not decrease even when the number of student site devices increases. To provide a distance education system.

In order to achieve the above object, the present invention is directed to a teacher site device and at least one student site device connected via a communication network, and the teacher site device is connected via the communication network. In the distance learning system in which predetermined teaching materials are provided to the student site device, the teaching material selecting means for selecting a teaching material provided from the teacher site device on the student site device is provided. It is configured as a featured distance education system. Further, the learning material selecting means can be configured to select the learning material based on, for example, the attribute of each learning material and the attribute of a target student. In this case, it is desirable that the attribute of the teaching material and / or the attribute of the student be transmitted from the teacher site device to the student site device as needed. Further, it is desirable that the teaching material selecting means can select the teaching material based on a request of a target student. The teaching material may be obtained from the teacher site device, or may be obtained from another device connected to the teacher site device.

[0005]

According to the distance learning system of the present invention, on the student site device, a process of selecting a teaching material provided from the teacher site device is performed based on, for example, the attributes and desires of the student. Therefore, the load on the teacher site is reduced, and the processing efficiency does not decrease even if the number of student site devices increases. If the teaching materials are stored on a site other than the teacher site, and information on the location of the teaching materials is stored on the teacher site, the load on the teacher site can be further reduced.

It is a schematic diagram which shows an example of the state of a browser. As shown in FIG. 1, the distance learning system A1 according to the present embodiment includes a teacher site TS, student sites SS1, SS2,... Connected via a communication network such as the Internet / intranet.
It is composed of SSn (collectively referred to as SS) and teaching material storage sites CS1 and CS2 (collectively referred to as CS) in which teaching materials are stored. The teaching materials stored in the teaching material storage site CS are HTML capable of inserting voices, still images, and moving images.
Created as a document. On the teacher site TS, teaching material management data (stored as a teaching material database), student data (stored as a student database), and teaching material selection logic are stored. The teaching material management data includes attributes of each teaching material and an address (URL) indicating the location of the teaching material. The student data is composed of attributes of each student. Also,
The teaching material selection logic (an example of the teaching material selection means) is transmitted to the student site after the communication with the student site SS is established, and is configured as an applet that operates on the student site. In addition, the student site SS has a preference setting function for setting a student's preference (such as an attribute of a teaching material to be learned), a learning material acquiring / displaying function for acquiring / displaying a teaching material,
An applet execution function for executing the learning material selection logic downloaded from the teacher site TS is provided, and these functions are specifically realized by an HTML document browsing program (browser). Further, a control program (not shown) for managing communication is installed on the teacher site TS and the student site SS, and data transmission and reception between the two sites is realized through the control program.

Next, a processing procedure by the remote education system A1 will be described with reference to FIGS. In this embodiment, the teaching materials are “Subject”,
It is divided into three levels: "Lesson" and "Unit". "Subject"
Is, so to speak, a “major classification”, for example, “basic communication”,
This is a learning subject such as "About Protocols".
“Lesson” is a topic that constitutes “medium classification” or the above “Subject”, and corresponds to learning contents such as “summary”, “about IP”, and “about TCP”. “Unit (unit)” is the substance content that constitutes the above “Lesson”, and corresponds to each OHP in a presentation, such as a drill and a test. Here, one "Unit" is one HT
It corresponds to an ML document. That is, "Lesson" is a set of HTML documents related to the same topic. In this embodiment, “Subject” and “Lesson” for each student
Is selected on the teacher site TS until the selection of “Un”.
The selection of "it" is performed by the above-mentioned teaching material selection logic on the student site SS. First, referring to FIG.
When the student starts the control program on the student site SS, a browser is opened on the screen by the control program. When a student accesses the homepage of the teacher site by inputting the URL of the teacher site into the URL input section of the browser (S1), the top screen of the homepage is displayed in the document display area of the browser (S1).
2). The displayed top screen is provided with a field for inputting a login name and a password, and the student inputs his / her login name and password in the fields (S3). At the teacher site, the input login name and password are authenticated. If the authentication is successful, the authentication result and the student ID are transmitted to the student site (S4), and the connection between the two sites is established. . When the connection is established, a list of subjects that the authenticated students can attend is first made on the teacher site. Specifically, an attribute (for example, grade) of the target student is extracted from the student database, and a Subject corresponding to the attribute of the student is listed from the teaching material database. The management data of the listed teaching materials is transmitted to the student site and displayed as a list on the screen (S5). When the student selects one from the list of subjects displayed on the screen and clicks a button displayed on the screen with a mouse, for example, the ID of the selected subject is transmitted to the teacher site ( S6). Next, on the teacher site side,
As in the case of the Subject, selected by the student
Lessons that the student can attend in the subject are listed, and management data of the listed teaching materials is transmitted to the student site (S7). At the student site, one is selected from the list of Lessons displayed on the screen by using a function such as a search as necessary (S
8, S9). When the start button is pressed by the student, the selected Subject and Lesson ID are transmitted to the teacher site (S10). On the teacher site, the units that the student can attend in the selected lesson are listed. The description will be continued with reference to FIG. At the student site, the child browser is opened by the control program at the same time when the start button is pressed (S11). This child browser, as shown in FIG.
It is divided into two frames, a display area of the TML document and an execution area (information display area used by the applet) of the teaching material selection applet. When the child browser is opened on the student site, the listed management data of the unit, the student data, and the teaching material selection applet are transmitted from the teacher site to the student site (S12). The student site sets up the received unit management data (table of contents) and student data (S13), and executes the received teaching material selection applet based on this (S14).
At this time, the student can also specify (preference) the attributes of the Unit that he or she wants to learn.

An example of the teaching material selection process (S14) using the teaching material selection applet will be described specifically with reference to FIG. 4. Prior to this, the attributes of the unit and the attributes of the student data will be described. First, the attributes of Unit include the following, for example. Teaching material type: This is an attribute that indicates to which category the content of the Unit (HTML document) belongs, for example, the main point / text / keyword explanation / point explanation / example / drill. For example, such an attribute is necessary in order to respond to a student's need to “learn only keywords”. Score: This is used as a code in the test to identify the score (correct answer rate), and for other information presentation types, whether or not the user has already viewed the information. Prerequisite: This describes the condition of Unit ID and its score. Those that satisfy this condition will be presented to the students. For example, assuming now that Unit 1 is a test, the prerequisite for Unit 2 is that the score of Unit 1 is 90 or higher. The prerequisite for Unit 3 is that the score of Unit 1 is 50 or higher. The teaching material (Unit 2) can be selected according to the student's level, such as selecting supplementary teaching material (Unit 3) for a student who has a low score on the test. Keyword: Keyword indicating the content of the Unit. Sequence number: Each unit has a sequence number (1,
2,...) Are given to students in principle in ascending numerical order. Other attributes: Other attributes, such as the target grade, can be set. These other attributes are designated by a character string of <attribute name><operator><value> such as "attribute name = value". The attribute data of the teaching material is character string data in which such a set of “attribute, operator, value” is arranged by separating with a comma. For example, if Unit1 is a required teaching material for first-year junior high school students, "Grade = 1, Class = Must" is set. Here, Grade (student's grade) is related to the student's attribute, and in the determination of the suitability of the teaching material, it is checked whether or not Grade = 1 is included in the student's attribute. In addition, as attributes of the student data, attributes (student grade,
There are attributes related to preference data set by the student on the student site side. For the former, like other attributes in the Unit attribute above,
<Attribute name><operator><value> such as Grade = 1
Is specified as a character string. In the latter case, the type and keywords of the teaching materials to be learned are specified. Next, an example of the procedure of the teaching material selection process will be described with reference to FIG. 4. Selected Subject, Un listed in Lesson
Assuming that the set of it is S, the one with the youngest sequence number is first extracted from S, and this is set as t (S2
1). If the student's preference (for example, the type of learning material or keyword to be learned) is specified, it is checked whether or not the attribute of t matches this (S22).
If they do not match, the process returns to S21. Student preferences and t
If the attribute of the student matches the attribute of the student, it is checked whether or not the attribute of the student matches the attribute of t (the other attributes). For example, if Grade = 1 exists in the attribute of t,
It is checked whether Grade = 1 also exists in the student attribute (S23). If they do not match, the process returns to S21. If the student's attribute matches the attribute of t, it is checked whether the precondition of t is satisfied (S
24). For example, if “Unit1 score is 90 or more” is set as the precondition of t,
If the score of Unit1 is 90 or more, the above precondition is satisfied. If the above prerequisites are not satisfied, the above S2
Return to 1. If the above prerequisites are satisfied, the URL
Is acquired from one of the teaching material storage sites CS based on the above, and is displayed in the HTML document display area of the child browser (S25). When learning of t is completed, the process returns to S21. If there is no next unit to be extracted in S21, the processing regarding the subject and lesson ends here, and the opened child browser is closed (S21).
15). Then, as shown in FIG. 3, the student's course status and the like are transmitted to the teacher site, and the student data in the student database is updated (S16). As described above, in the distance learning system according to the present embodiment, the teaching material selection logic for selecting the teaching material (Unit) provided to the student is sent from the teacher site to the student site as a teaching material selection applet, and the student site side transmits the logic. Since the teaching material selection logic is executed, the load on the teacher site is reduced, and the processing efficiency does not decrease even when the number of student site devices increases.

[0009]

[Embodiment] In the above embodiment, the substance of the teaching material is stored in the teaching material storage site CS different from the teacher site, but may be stored on the teacher site. Also, in the above embodiment, only the unit of the teaching material is selected as the teaching material selection logic to be processed at the student site.
All of ect and Lesson may be selected on the student site.
