Description

  The present invention relates to an education system that performs education using a personal computer, a computer network, and the like, and more particularly, to an education system that performs learning smoothly while suppressing a reduction in learning effect even when a network failure occurs.

In recent years, the use of educational systems such as e-learning is increasing in higher education institutions and corporate training. E-learning is a form of learning with a high degree of freedom that is not constrained by local and temporal conditions. And as specific learning forms, the so-called “anytime” and “anywhere” asynchronous on-demand individual learning and the instructor conducts classes for multiple students all at once, and the instructor and students There is a synchronous type that performs cooperative learning synchronously. In the synchronous type, it is possible for the student to ask the instructor questions in real time via the computer network. In addition, it is also possible to share information on student questions and instructor answers among students. For this reason, the synchronous type is considered to have a higher learning effect than the on-demand type.
For such an environment, there is an education system disclosed in Japanese Patent Application Laid-Open No. 2004-199506 as a background art of the present invention, which will be described below.

  The present invention provides a management server that receives the attendance status information of each student from a plurality of attendee terminals connected via a network and manages the attendance status of each attendee determined based on the attendance status information. It is a prepared attendance status grasping system. The management server includes a program distribution unit, an information registration processing unit, a attendance state determination processing unit, a warning processing unit, and a storage unit. In addition, the attendance state determination processing unit obtains attendance state information including biometric information from the attendance state information transmission processing unit of each student terminal connected via the network, and compares it with reference information stored in advance in the storage unit The attendance status of each student is determined based on the result. The attendance state determination processing unit instructs the warning processing unit to perform warning processing according to the determination result, and displays the attendance state of each student based on the determination result on the lecturer terminal.

  As a result, since the attendance status of each student is determined based on the attendance status information including the biometric information, it is possible to accurately grasp the attendance status for each attendee, and the instructor is in the determined attendance status. Based on this, it is possible to appropriately handle individual responses.

  Moreover, as an education system as a background art of the present invention, there is one disclosed in Japanese Patent Application Laid-Open No. 2003-44320, which will be described below. The educational system of the present invention comprises at least one management terminal and at least one monitored terminal connected thereto. The management terminal notifies the monitored terminal of a specific operation to be monitored and a condition for notification of occurrence. The monitored terminal notifies the management terminal of the occurrence when a specific operation to be monitored occurs based on the notification from the management terminal and the occurrence notification condition is met.

As a result, in the education system, when a specific operation to be monitored occurs and the occurrence notification condition is met, the monitored terminal is notified to the management terminal. You can know the operation of in real time. In addition, a teacher who is using the management terminal can immediately cope with a failure such as a screen freeze or a student's absence without special burden.

However, in synchronous learning, if a network failure occurs, all data communication including student management becomes impossible, and it is impossible to continue taking synchronized lectures. It becomes difficult to hope for the learning effect. Note that the network failure means that, in connection with a remote place, a sufficient transmission bandwidth cannot be ensured depending on the situation at that time, a transmission delay of an image or sound occurs, or the connection is suddenly interrupted. As an example of a specific network failure, there is downtime (line disconnection due to rain attenuation) that occurs when using a wireless LAN in an area where a wired LAN (Local Area Network) cannot be used.
Here, an experiment for measuring under what conditions the downtime occurs will be described below.

  FIG. 12 shows a measurement apparatus for disconnecting a wireless LAN. The measurement contents include communication confirmation by PING (Packet Internet Grouper), quality confirmation in streaming reproduction of moving images, and the like. PING is transmitted wirelessly from the antenna 24 from the measurement personal computer 121 via the hub 23 and the transceiver 22, and after reaching the measurement personal computer 121 via the antenna 24, the transceiver 22 and the hub 23. The communication confirmation is performed by arriving at the measurement personal computer 121 of the transmission source through the route returning from the measurement personal computer 121. The moving image is wirelessly transmitted from the digital video 123 via the MPEG2 encoder 122, the hub 23, and the transmitter / receiver 22 and from the antenna 24, and is transmitted for measurement via the antenna 24, the transmitter / receiver 22, and the hub 23. It is confirmed whether or not the data can be received by the personal computer 121.

  FIG. 13 shows a measurement area for wireless LAN line disconnection. The measurement area is indicated by a broken line. Measurement section is 8.2km section from Uwatarijima to Hadomisaki in the northern part of Saga Prefecture, 4.2km section from Hadomisaki to Kagajima, 3.2km section from Kagajima to Ogawajima, and Karatsu City to Takashima It is a 3.5km section until.

  FIG. 14 shows the measurement results of the received electric field strength during rainfall in the northern region of Saga Prefecture. TMON (transmission monitor: ON) is indicated by a dotted line, TEMP (Temperature) is indicated by a one-point difference line, and AGC (Auto Gain Control) is indicated by a straight line. A portion surrounded by a circle in the figure shows a state where the line is disconnected.

  FIG. 15 shows a communication confirmation result by the PING command. As shown by ◎, in the 8.2km section from Hadomisaki to Mawatarijima, the command speed is 54Mbps, IEEE802.11g is used, the data length is 15.36 bytes, the time is 1 minute, and the command is sent 16 times As a result, the number of timeouts that could not be received was 13. This indicates that a line disconnection has occurred.

  FIG. 16 shows meteorological data in February 2004 in the measurement area. As indicated by ◎, on February 22, 2004, when the measurement was performed, precipitation of 31 mm and maximum precipitation of 11 mm per hour were observed. This indicates that the line is disconnected due to rain because radio waves are easily absorbed by water.

  Here, an example of downtime is shown, but there is a possibility of a network failure not only in a wireless LAN but also in a wired LAN. For example, when using ADSL (Asymmetric Digital Subscriber Line), when selecting a best-effort type communication network or service that does not guarantee the quality of service without selecting a guarantee type that guarantees the quality of service. May be difficult to secure bandwidth. Even in a highly reliable network, there is a possibility that a network failure for any cause including a user's operation mistake or the like may occur.

(First embodiment of the present invention)
A first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a system configuration diagram of an education system according to the first embodiment of the present invention. The server 1, the student terminal 2, and the administrator terminal 3 are configured. When constructing a system, not only a wired LAN but also a network including a wireless LAN, and a voice line such as a telephone line are possible.

  FIG. 2 is a network configuration diagram of the education system according to the first embodiment of the present invention. When constructing a wireless LAN, data is input to and output from the administrator terminal 3. Next, it is processed by the server 1 as necessary, and is transmitted by the antenna 23 via the broadband router 21 and the transmitter 22. And after receiving with the antenna 23, it inputs / outputs in the student terminal 2 via the receiver 22 and the hub 24. FIG. A telephone and a FAX 25 are connected through a carrier network 26.

  FIG. 3 is a hardware configuration diagram of the education system according to the first embodiment of the present invention. The student terminal 2 and the administrator terminal 3 include a CPU 31 as an arithmetic processing means, a RAM 32 as a storage means, a ROM 33, a flash memory 34, a hard disk 35, a mouse 36 as an input means, a keyboard 37, a printer 38 as an output means, and a display means. It comprises a display 39 and a LAN card 310 as communication connection means. Note that the administrator terminal 3 can be connected to a modem 311 by telephone or FAX 25.

FIG. 4 is a flowchart of the education system according to the first embodiment of the present invention.
First, as a start, the student prepares for the class by logging in at the student terminal 2. At that time, in the student terminal 2, SLMS (learning management mechanism: hereinafter referred to as SLMS) for managing learning of the student is activated. In addition, in the administrator terminal 3, the administrator has an ALMS for learning management (hereinafter referred to as ALMS) in order to promote the learning of the students for each learning unit and to synchronize the students. to start. Note that the SLMS can have a learning material usage status, learning progress status, learning result recognition, self-evaluation, communication status confirmation, synchronous type and on-demand type switching or recognition functions. ALMS has functions such as monitoring the history of each student's use of learning materials, monitoring the communication status, monitoring the student's lecture status, switching or recognizing synchronous and on-demand types, etc. Can do.

  First, teaching materials necessary for the unit are transmitted from the server 1 to the student terminal 2 (S401). The learning material is stored in a learning material database in the server 1. The teaching material can also be stored in the administrator terminal 3. Moreover, after transmission, it is stored in a storage means such as the hard disk 35 of the student terminal 2. The contents include reproduction animation, presentation, chat 66, BBS101 (Bulletin Board System), pronunciation software, mathematical expression software, three-dimensional display software, and the like.

  When the class start time comes, the received teaching material is started by the browser of the student terminal 2 (S402). What is started is mainly the playback video and presentation data stored in the student terminal 2. The contents of the lecture participants' chat 66 and the BBS 101 are input / output from the student terminal 2 and the administrator terminal 3 through the keyboard 37 and distributed via the server 1 at any time.

The administrator terminal 3 sends a PING to the student terminal 2 at predetermined intervals to check whether there is a network failure. Similarly, a PING is sent from the student terminal 2 to the administrator terminal 3 at a predetermined interval for confirmation (S403).
The ALMS of the administrator terminal 3 and the SLMS of the student terminal 2 determine whether a network failure has occurred (S404).

  When the ALMS of the administrator terminal 3 and the SLMS of the student terminal 2 determine that a network failure has occurred, the ALMS notifies the administrator (S405). SLMS will notify students. Then, the SLMS switches to the on-demand type and continues the lecture using the teaching material excluding the chat 66 and the BBS 101. Here, since the distribution of the chat 66 and the BBS 101 from the server 1 is stopped due to the line disconnection, if there is a question, it is performed by telephone or FAX 25. The instructor posts the contents of the question received from the student by telephone and FAX 25 through the server 1 from the administrator terminal 3 to the chat 66 and the BBS 101 and distributes the contents to the student terminal 2 without line disconnection. In this case, information received by telephone or FAX 25 can be input to the administrator terminal by voice recognition, a character recognition program, or the like.

Thereby, even when a line disconnection occurs, the student can maintain the same learning effect as the learning type in the synchronous type.
The ALMS of the administrator terminal 3 and the SLMS of the student terminal 2 determine whether or not the network terminal has recovered from the network failure (S406).
If the network failure has not been recovered, the on-demand learning is continued (S405).

When it is determined that the ALMS of the administrator terminal 3 and the SLMS of the student terminal 2 have recovered from the network failure, the administrator confirms how much the student has learned during the network failure (S407). . In addition, the learning progress of the student who has the latest progress is confirmed in the learning progress of other students.
Then, it is determined whether or not to return to the synchronous type in consideration of the student's progress until the end of the unit (S408). Specifically, if other students who have continued learning on demand type have completed the unit, the lecture will be given by the synchronous type synchronized with the other students from the next unit.

  When the administrator determines to return to the synchronous type, ALMS changes the target student terminal 2 to the synchronous type. Then, the synchronous learning is continued (S409). The chat 66 and the BBS 101 are restored when a line is connected on the screen regardless of switching from the on-demand type to the synchronous type, so that the student performs an update operation. However, the SLMS can be automatically updated when switching from the on-demand type to the synchronous type.

If the administrator determines not to return to the synchronous type, the on-demand type learning is continued (S405). In addition, when the unit is completed, a small test in the teaching material distributed in advance is taken. The small test is a test for confirming the learning achievement level similar to WEBTEST in the synchronous type. The student terminal 2 has means for performing a failure learning achievement test as a small test. Note that the test result is not transmitted to the administrator terminal 2 because a network failure has occurred. Therefore, the administrator terminal 2 determines the learning achievement level of the student by having a failure learning achievement level test determination means for determining the learning achievement level. Then, according to the determination result of the learning achievement test at the time of failure, the review unit is performed when the determination result is bad, and the next unit is selected when the determination result is good.
If the ALMS of the administrator terminal 3 and the SLMS of the student terminal 2 determine that no network failure has occurred, the synchronous learning is continued (S409).

  FIG. 5 is a synchronous unit selection flow sheet according to the first embodiment of the present invention. Since lectures are progressed on a unit-by-unit basis, the administrator will adjust the progress of the lectures to the latest students. A unit is a segment of teaching material. For example, in the case of mathematics, it is a calculation of a character formula, a numerical sequence, an exponent / logarithm, a vector, a matrix, and the like. The Therefore, the administrator first confirms that the unit has been completed (S501). Then, an instruction to receive WEBTEST for confirming the learning effect is issued (S502). WEBTEST is a test for the administrator to confirm the achievement of learning for each unit from the student in the synchronous mode. The administrator confirms whether all the members are finished (S503). If not all of them have been completed, an instruction to receive WEBTEST for reconfirming the learning effect is given to the students who have finished the unit lecture before the students who are still in the lecture are finished ( S504). When all the units are completed, the process proceeds to the next unit (S505).

  Note that the administrator obtains test result information in order to determine whether to proceed to the next unit based on the result of WEBTEST (S506). Then, it is determined whether or not a predetermined score is obtained (S507). If the score is not higher than the predetermined number, a unit for review is performed (S508). If the predetermined score is obtained, the process proceeds to the next unit (S509).

  FIG. 6 is an example of a screen display of the student terminal of the education system according to the first embodiment of the present invention. The screen of the student terminal 2 is displayed on the display 39. The replay video 61 of the lecture material is a video in which a lecturer is taking a picture of a lecture in front of the camera. The auxiliary teaching material 62 is for reinforcing the lecture contents. The student's video 63 is a picture of attending a lecture. The instructor 64 in the auxiliary teaching material plays a leading role in using the auxiliary teaching material. The chart teaching material 65 illustrates, for example, a graph or an experimental instrument. The chat 66 is for the student to ask the instructor a question that arises during the lecture. Data input from the questioner's student terminal 2 using the keyboard 37 or the like is sent to the other student terminals 2 and the administrator terminal 3 through the server 1 and displayed on each terminal. Further, the content of the instructor answering the student's question from the administrator terminal 3 is sent to the student terminal 2 via the server 1. Even when the BBS 101 is displayed, the same processing as in the chat 66 is performed. Here, chat is a system that performs character-based conversation in real time through a computer network. The BBS is an electronic bulletin board service that can be read and written by all students and managers.

  Here, the server 1 receives a question or the like transmitted from one student terminal 2 via the network, and provides the chat 66 and / or the BBS 101 that is transmitted to the administrator terminal 3 and the other student terminals 2. have. The server 1 also has a means for providing the chat 66 and / or the BBS 101 that receives the response transmitted from the administrator terminal 3 via the network and transmits it to all the student terminals 2. Further, the manager terminal 3 and the student terminal 2 display the character information such as questions and answers received from the chat 66 of the server 1 and / or the providing means of the BBS 101 on the display screens of the manager terminal and the student terminal. Also have. The lecture status screen 67 displays a history of units, teaching materials, etc. recorded in the SLMS. If a network failure occurs, the chat 66 screen cannot be displayed. Also, an alarm indicating that a network failure has occurred from SLMS is displayed. For example, a message indicating that a network failure has occurred can be displayed on the screen together with an alarm sound. Furthermore, messages such as chat 66 and BBS being unavailable due to a network failure and notification of confirmation to the administrator can be displayed on the screen.

FIG. 7 is an example of a screen display of the administrator terminal of the education system according to the first embodiment of the present invention. On the display 39 of the administrator terminal 3, the contents displayed on the display 39 of the student terminal 2 are displayed for each student. Here, when a network failure such as line disconnection occurs, the chat 66 cannot be displayed like the screen 71 of the student terminal with the line disconnected surrounded by a broken line in the figure.
Further, when a network failure occurs, an alarm indicating that a network failure has occurred from ALMS and which student terminal 2 the trouble has occurred are displayed on the display 39 of the administrator terminal 3. In addition, although shown with the dotted line in the figure, the case where it colors is also possible.

  FIG. 8 is an example of a WEBTEST screen display in the student terminal of the education system according to the first embodiment of the present invention. The result of the TEST performed by the student taking the synchronous type is recorded in the SLMS of the student terminal 2. Then, it is transmitted to the ALMS of the administrator terminal 3 through the SLMS of the student terminal 2. The administrator confirms the learning effect of the student through ALMS. In addition, the evaluation for the learning effect is recorded also in ALMS. Here, the evaluation with respect to the learning effect means a learning achievement level based on the result of the WEBTEST. As a specific example, the result of WEBTEST is 80 points or more as pass, and the case of 80 points or less is rejected. Furthermore, in the case of failure, it is confirmed which part of the unit is insufficiently understood from the problem of incorrect answer. Therefore, it is possible to implement the evaluation method for the learning effect as a learning achievement test result determination unit on the server 1 or the administrator terminal 2 or the like.

  Further, based on the result of WEBTEST, if the test result is bad, review of the incorrect answer part of WEBTEST in the unit and exercises are performed, and if the test result is good, the next unit is advanced. These can also be implemented in the server 1 or the administrator terminal 2 as unit selection means.

  In the present embodiment, the lecturer can also give a lecture live in the synchronous type. For this purpose, a device and a mechanism for synchronizing the student and the administrator such as a camera, a microphone, and an MPEG encoder are required. In such a live type, each student cannot stop, fast forward, or rewind the live video of the lecture at the student terminal 2.

  When a network failure such as a line disconnection occurs, SLMS records the part that could not be taken, and re-lectures on a synchronous or on-demand basis at another opportunity. In the lecture using the playback video, since there is a record such as a BBS when the lecture is performed in the live type, the learning can be performed while suppressing the reduction of the learning effect in the live type.

(Other embodiments)
[Learning unit and learning mode selection system based on automatic learning progress determination]
In S408 of FIG. 4, the SLMS of the student terminal 2 that has been disconnected transmits the learning progress data to the server 1, and the learning progress data of the student with the slowest learning progress of the ALMS of the administrator terminal 3 Compared to the above, it is possible to use means for automatically selecting a learning unit, a synchronous type and an on-demand type of learning. FIG. 9 is an explanatory diagram of automatic learning progress determination of an education system according to another embodiment of the present invention. Student A is a student at a student terminal in which a network failure has not occurred, and student B is a student at a student terminal in which a network failure has occurred. The solid line indicates the time of occurrence of the network failure 91, the broken line on the left indicates the unit (sequential number) 92, the broken line on the right indicates the unit (vector) 93, and the black line indicates the learning progress of the students A and B Represents. (1) shows that when student A is taking a synchronous and vector unit lecture, student B who has a network failure (on-demand type) takes the course after returning from a network failure. The case where the lecture of the unit of the same vector as the person A was taken is shown. In such a case, the learning progress automatic determination means selects to immediately shift to the synchronous learning mode because the learning progress is the same unit. (2) shows that when student A is taking a synchronous and vector unit lecture, student B who has a network failure (on-demand type) It shows the case of taking a unit of several sequences. In such a case, the learning progress automatic determination means selects the student A not to proceed to the next unit, and further selects the student B from the next vector unit of the sequence of units to the synchronous type. Choose to move to learning mode. In addition, when not progressing to the next unit, the student A will perform WEBTEST. (3) shows that when student A is taking a series of lectures in a synchronous format, the student B who has a network failure (on-demand type) has already recovered from the network failure. It shows the case of taking a vector unit. In such a case, the learning progress automatic determination means makes a selection for the student B not to proceed to the next unit until the student A finishes the vector unit. Then, when the student A proceeds to the vector unit, the student B also shifts to the synchronous type without proceeding to the next unit. In addition, the student B performs WEBTEST, when a unit cannot be advanced.

[Lecture playback video and chat and BBS synchronization system]
In FIG. 6, the question and answer in the chat 66 or BBS 101 input from the student terminal 2 or the administrator terminal 3 are recorded when the time stamp or the number of frames of the replay video 61 is recorded and the replay video is played again. In the chat 66 or the BBS 101, the question and the answer can be followed and displayed. FIG. 10 is an example of a system for synchronizing a playback moving image and a BBS of a lecture in an education system according to another embodiment of the present invention. In the reproduction animation 61 in the figure, the subject is mathematics and the unit is a simultaneous equation. The reproduction moving image 61 in which one frame is 30 minutes has 54000 frames. Here, when a question is input from the student A to the BBS 101 10 minutes after the lecture is started, it is recorded that there was a question at the BBS 101 in 18000 frames 10 minutes after the playback video 61. The same applies when there is a response from the administrator. Then, when the lecture of the playback video 61 is taken at the next opportunity, the recorded question and answer contents to the BBS 101 are posted 10 minutes after the start of the playback video 61. Further, the display format on the BBS 101 for questions and answers can take a tree structure. For example, with respect to the question of the student A, the administrator's answer and the opinion of the student B can be displayed in a subordinate format, or questions of the same theme can be displayed in parallel. Here, the student terminal 2 transmits to the server 1 data such as a subject identification number, a unit identification number, a sender, a time stamp, a frame number in a reproduced moving image, and the content of a statement. The server 1 has time stamp insertion means for inserting the time stamp transmitted to the BBS 101 into the frame of the playback video, further organizes the data such as the subject identification number and unit identification number, and the playback video and the BBS 101 are It has playback video playback / question / answer display synchronization means for synchronous display. Then, it is distributed from the server 1 to each student terminal 2. Note that the chat 66 can be processed in the same manner as the BBS 101. However, the BBS 101 requires a student update operation, whereas the chat 66 is different in that it is continuously distributed from the server 1.

The student terminal has means for recording data such as a subject identification number, a unit identification number, a sender, a time stamp, a frame number in a playback video, a content of speech, etc. when a network failure occurs. Data can be automatically transmitted to a server and an administrator terminal many times.
As a result, when a student who has a network failure, such as when returning from a network failure, plays the playback video again, the content of the question of the student with a network failure is displayed. Can learn while suppressing the reduction of the synchronous learning effect.

[Distribution system of learning materials based on prior weather forecast]
In S401 of FIG. 4, when the teaching material is distributed from the database, the content of the teaching material to be distributed in advance can be changed according to the weather information acquired in advance.
FIG. 11 is an example of a learning material distribution system based on prior weather information of an education system according to another embodiment of the present invention.

  As for the contents, data such as weather, precipitation, wind speed, etc. at the time of the lecture is acquired by accessing the terminal 111 on which the homepage of the Japan Meteorological Agency or weather forecast service is posted. For this purpose, the server 1 has weather information acquisition means 112. Based on the information, the location of the student terminal 2 scheduled to take a lecture in an area where the weather is bad is confirmed. For this purpose, the server 1 has information acquisition means 113 for the location of the student terminal. Furthermore, based on the above information, for example, when the amount of precipitation is expected to increase in an area where a wireless LAN is used, a teaching material distributed in advance from the server 1 is assumed assuming that a network failure may occur. The amount of teaching materials can be adjusted to suit the weather conditions expected during the lecture time. For this purpose, the server 1 has a transmission teaching material selection means 114. Note that when distributing the teaching material, the priority order from the server 1 to the student terminal 2 to be distributed can be determined based on the position of the student terminal 2 and the data of the weather conditions. For example, it can be distributed from the student terminal 2 in the region where the probability of precipitation is 100%, and then the student terminal 2 in the region of 90% and the student terminal 2 in the region of 80%.

  As a result, when teaching materials are sent for each unit, it is possible to send the teaching materials for multiple units to students in areas where the weather is bad, and continue quickly even if a network failure occurs And can learn.
