| Research Abstract |
This research was undertaken to assess the value of the possible LAN instruction system where an instructor can administer to language learners at a free instructing layout.
This instruction system was made possible with the use of the light diffusion-transfer wireless infrared ray transmission system and a notebook computer. The system 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.
In the system a program to transfer information between an instructor and learners in a computer class is being operated. In addition, two-way voice communication system between an instructor and learners is built in. This resulted in the instruction system to cope with the need of improving four skills as "reading," "writing," "listening," and" "speaking".
There is, however, a problem found in the system, in that the two-way voice communication system can not be operated real-time. As sound gaps seen in satelite broadcasting and heard in overseas calls often discomfort us, the sound gap of over one-second delay has been observed.
This research has arrived at the conclusion that foreign language education utilizing wireless infrared ray transmission system may convenience and even economize the whole education plan, in that learners only need to bring in their own notebook computers into the ordinary classroom, not an extravagant LL or a computer room.
