Research Abstract

This research was undertaken to assess the value of the possible instruction system where an instructor can administer to language learners at a free multimedia instructing and learning layout.
This instruction system was made possible with the use of the light diffusion-transfer infra-red ray transmission system and a notebook computer. The system can use three different wavelengths. The first one is used for transferring NTSC (National Television Standards Committee) signal with analog spectrum. This transmission causes no delay distributing information from the instructor to the learners. The rest of them are used for wireless LAN utilizing infra-red ray. This system of the LAN uses CSMA/CD (Carrier Sense Multiple Access with Collision Detection) which has been adopted in IEEE802.3 10BASE-T, thus excelling CSMA/CA (CSMA with Collision Avoidance) in detecting a signal collision.
There is, however, a next research issue found in the system. The system could operate the two functions simultaneously, by presenting audio-visual teaching materials to learners, and the learners controlling the playback of the materials by themselves. Then, the further research accounting for the effective chemistry between the two is needed.
This research has arrived at the conclusion where foreign language education utilizing three infra-red rays transfer on the different wavelength may rejuvenate and even economize the whole education plan, in that instructors and learners only need to bring in their own notebook computers into the ordinary classroom, not into an extravagant LL or a computer room.
