DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collective language training apparatus and a collective language training method that enable a teacher to grasp the individual learning situation of each student by using moving images and sounds. ) LL device that combines equipment,
And a group language training system using the LL device.

[0002]

2. Description of the Related Art In a conventional collective language training apparatus, in order for a teacher to grasp the individual learning situation of each student in order to improve the educational effect of the collective education, individual learning guidance and grasping using only voice can be used. It was not possible.

[0003] In addition, the handling of moving images is very primitive, in which VTR images sent simultaneously by a teacher are displayed on a CRT (cathode ray tube display) group installed at an arbitrary place in a classroom. Was.

As a conventional technique in which a teacher pays attention to a collective language training apparatus and method for improving the learning effect by grasping the individual learning situation of each student, Japanese Patent Laid-Open Publication No. Hei 3-6587 (hereinafter referred to as Conventional Technique 1) The group language training device described in (1) is used to selectively play and listen to the voices of other learners in addition to the teacher's voice and his / her own voice when conducting group education. The audio data was stored in the audio information memory so that it could be used.

The language learning apparatus described in Japanese Patent Application Laid-Open No. 64-29889 (hereinafter referred to as “prior art 2”) allows students to freely select teaching materials from video teaching materials prepared by teachers according to their own interests. It made it possible to select and to provide a variety of learning offers.

The language learning apparatus described in Japanese Patent Application Laid-Open No. 63-56681 (hereinafter referred to as prior art 3) enables students to answer questions by voice in group language education. Interest in
It made it possible to enhance the learning effect.

Further, in the collective learning apparatus described in Japanese Utility Model Laid-Open Publication No. 3-11038 (hereinafter referred to as prior art 4), a mode in which the teaching material is recorded on one of the two tracks of the recorder on the student side and a mode in which both are simultaneously recorded. By switching the recording mode and using it, it was possible to use it according to the purpose of language learning.

[0008]

As described above, in the techniques disclosed in the prior arts 1 to 4, there is a method for completely grasping the individual learning situation of each student using a moving image. No equipment and method.

[0009] In the conventional group language training apparatus and method,
Although the teacher was able to grasp the individual learning status of each student only by voice, it was not possible to grasp the individual learning status of each student using moving images. As described above, in the conventional group language training apparatus and method, there is a problem of insufficient communication means such that the speaker's visual information such as the mouth movement and the facial expression of each student is not transmitted to the teacher at all. Therefore, it does not mean that all the tasks expected in the original teacher's instruction are correctly digested.

Therefore, the technical problem of the present invention is to provide not only voices from each student but also visual information such as mouth movements and facial expressions in the instruction of teachers in foreign language group education. It is an object of the present invention to provide a collective language training apparatus and method capable of providing guidance for enhancing the integrated language utterance ability incorporated.

[0011]

According to the present invention, at the time of the teacher's guidance in the LL class, the teacher is required to grasp each individual student's individual learning situation. A collective language training device configured to provide guidance to improve overall language utterance ability by grasping not only voices but also visual information such as mouth movements and facial expressions with moving images.
