JP5074337B2 - Portable information terminal, timetable posting / information relay device, and attendance management / display content control system - Google Patents

Description

  The present invention relates to a portable information terminal, a timetable posting / information relay device, and an attendance management / display content control system.

  Electronic textbooks (electronic books, terminals) that can record various contents may be used in educational settings. Students can browse textbooks without worrying about physical paper thickness. Also, even if the course contents change for each subject, it is not necessary to change the terminal, and only the contents should be changed.

  On the other hand, it is also possible to display content that has nothing to do with the current subject content. It is inconvenient for the instructor to display content that is not related to the content of the course. It is desired to create a mechanism that selects content and displays only the content related to the subject.

  In addition, attendance confirmation at the educational site so far has only been confirmed at a certain point in time. This is unavoidable because the act of confirming attendance is part of the class. However, this makes it easier to cheat as if he / she is attending even when he / she is not actually attending, which is undesirable in attendance management.

  As peripheral technologies, for example, in Patent Document 1, a storage device that stores material information, a display device that selectively displays the stored material information, a plurality of personal display devices, and material information between the devices A conference material display system having a control unit for controlling the delivery of the conference is shown.

Patent Document 2 discloses a correspondence education system using digital paper. In this system, students take a test displayed on digital paper. Test answers are sent during distance learning. During the distance learning period, the student's progress is ascertained from the test results, and problems suitable for the student are selected and transmitted to digital paper.

Le computer and 7, the constructed.

The timetable server 1 manages a database (table) that stores timetable information indicating classes conducted for each day of the week and each time period of each classroom.
The attendance server 2 manages attendance databases (tables) storing attendance information for each class for students taking classes in each classroom.

The learning material server 3 manages a learning material database (table) storing learning material information (learning materials or contents of auxiliary teaching materials) used in each class.
The timetable posting / information relay apparatus 4-1 receives the timetable information of the classroom (classroom A) from the timetable server 1 and outputs it on the display unit of the own apparatus to post the timetable, 2 and the teaching material server 3 and the exchange of information with each electronic textbook (each terminal) in the classroom (classroom A) is relayed. The same applies to the timetable posting / information relay device 4-2.

Tables managed by the attendance server 2 include the following (1) to (3).
(1) Student information table having student name, student ID, terminal ID, and terminal address (2) Terminal address, each polling time in the attended class, and reply information for each poll ( Attendance information table (3) class name, terminal address of the student attending the class, and the second memory (to be described later) of the terminal A student information table for each class having a starting address of the teaching material contents and a flag indicating whether or not the teaching material contents of the class have been downloaded. Has an information table.

Next, the operation of this system will be described with reference to FIGS.
First, at a predetermined time (for example, a time just before the start of a day's class), each class (A classroom, B classroom,...) From the timetable server 1 in FIG. Timetable information is transmitted to the timetable posting / information relay apparatuses 4-1, 4-2,.

  For example, in FIG. 2, the timetable information 9 of Class A is transmitted to the timetable posting / information relay apparatus 4-1 installed in Class A at (1). Of course, the timetable information is also transmitted to other B classrooms.

  Also, in the case of a cancellation or a sudden subject change, the timetable information reflecting the change is transmitted to the timetable posting / information relay device of the target classroom. For example, FIG. 2 shows a case in which the two-time period of Wednesday in classroom B is changed from subject D to subject Z in (2). In this case, the timetable information for classroom B reflecting the contents of the change is transmitted to the timetable posting / information relay device 4-2 for classroom B and posted on the display means.

Returning to the description of FIG.
Subsequently, in (2) of FIG. 1, a student information table for each class for the class is transmitted from the attendance server 2 to the timetable posting / information relay apparatus 4-1. Further, in (3) of FIG. 1, the teaching material content (contents of auxiliary teaching materials) for the class is transmitted from the teaching material server 3 to the timetable posting / information relay apparatus 4-1.

  The timetable posting / information relay device 4-1 refers to the item of “flag indicating whether or not the teaching material content of the class has been downloaded” in the received student information table for each class. If it is determined from the flag value that the learning material has not yet been downloaded to the student's terminal, the learning material content for the class received from the learning material server 3 is downloaded. This download is sequentially performed from the timetable posting / information relay apparatus 4-1 to each terminal. When a response indicating that the download has been completed normally is received from the terminal, the value of the “flag indicating whether or not downloaded” for the terminal is set to “on” indicating that the download has been completed.

  For example, in FIG. 3, since the supplementary materials have not yet been downloaded to each terminal for the subject D on Wednesday in Class B, the supplementary materials are downloaded from the teaching material server 3 to the classroom B in (1) of FIG. As shown in (2) of FIG. 3, the auxiliary material is transmitted from the time schedule posting / information relay apparatus 4-2 to the selected memory of each terminal as will be described in detail later. Downloading to a dedicated area.

  On the other hand, the timetable posting / information relay apparatus 4-1 has already downloaded the teaching material of the subject to the student's terminal from the value of “flag indicating whether or not downloaded” in the received student information table for each class. 1 (4) in FIG. 1 shows the subject information including each “start address” in the student information table for each class from the timetable posting / information relay device 4-1 to each terminal. Then, the teaching material content of the subject is displayed on the display device of each terminal.

Also, attendance polling (attendance request) is performed for each terminal in (5) of FIG. 1 using each terminal address of the student information table for each class received from the attendance server 2.
A (passive) tag in which ID information of the classroom is embedded is installed near the upper surface of each desk in the classroom. When the terminal is placed on the desk, the classroom ID information of the tag on the desk surface is read by radio waves emitted by the tag reader of the sensor unit built in the terminal. Then, the read ID information is notified from the sensor unit to the communication unit built in the terminal. When the communication unit receives an attendance poll, it determines whether the classroom ID of the classroom where the timetable posting / information relay device is installed is the same as that notified by the sensor unit. Only when they match, the self ID (that is, the terminal ID) is returned to the attendance polling.

  Such attendance polling is performed a plurality of times at random intervals for one terminal (electronic textbook) during one class. The result of multiple attendance polls for each end includes the terminal address, each polling time in the class attended, and reply information for each poll (terminal ID when present, NULL when not present) The attendance information table is transmitted from the timetable posting / information relay apparatus to the attendance server 2 and stored in the attendance server 2 in (6) of FIG.

FIG. 7 is an overall flowchart of the present embodiment.
In step S1 of FIG. 7, the time is confirmed. In other words, each subject of each classroom is read from the timetable server 1 at a time just before the start of each timed class. For example, as shown in the following step S2, here, the time is a little before the start of the second period, and the case of the classroom B in the second period on Monday of Class A is taken as an example. In this case, as shown in step S3, the student information table for each class for the subject B and the attendance polling instruction for the subject B are sent from the attendance server 2 to the timetable posting / information relay device for the classroom A Made.

  The timetable posting / information relay device of Class A that has received these pieces of information sequentially transmits the “Subject B” code to each terminal (each electronic textbook) in the classroom in Step S4. That is, information including a memory selection instruction permitting only access to a predetermined second memory and the start address of the teaching material contents of the lesson B is transmitted.

  In the terminal (electronic textbook) that has received this “text subject B” code, the memory is selected. That is, the second memory storing the education-related content is designated as an accessible area, and access to another memory area (for example, the first memory) is prohibited.

  On the other hand, as a continuation of step S4, the timetable posting / information relay device in classroom A starts attendance polling for each terminal (each electronic textbook) in step S5 '. In this method, each terminal is polled a plurality of times at random intervals during the second period. In step S6, the terminal (electronic textbook) that has received this attendance polling confirms the classroom in which it is present, and then returns a reply with its own ID (terminal ID) added to attendance polling.

In the timetable posting / information relay device of classroom A, the reception time and terminal ID are accumulated and recorded for each terminal in step S7.
Subsequently, in step S8, the timetable posting / information relay device in classroom A determines whether or not the end time (10:50) of the second period (10: 00-10: 50) has been reached. If the end time has not been reached, the process returns to step 5 ′ to continue attendance polling for each terminal.

When the end time has been reached, the timetable posting / information relay device in classroom A ends attendance polling and uploads the accumulated information to attendance server 2 in step S9.
Subsequently, in step S10, a counting process on the attendance server 2 side is performed. For example, in the second time period, when each terminal is polled for attendance confirmation five times at random intervals, the number of times the self ID is returned among the five times is calculated as the attendance occupancy rate. For example, the attendance occupancy rate of a terminal that has returned its own ID four times out of five times is 0.8. Then, a threshold is set for the attendance occupancy rate, and it is determined that the attendance in the class (the subject) exceeds the threshold.

  On the other hand, as a continuation of step S9, the timetable posting / information relay device in classroom A sequentially sends an instruction to cancel the “subject B” code to each terminal (each electronic textbook) in the classroom in step S10 ′. That is, an instruction for returning the access control to the memory to the initial state is transmitted.

  In the terminal (electronic textbook) that has received the instruction to cancel the “subject B” code, the memory selection is cancelled. That is, all contents can be browsed regardless of the area.
