This document summarizes the operation procedures and limitations of an educational technology system used for language learning. The system allows students to access language programs through broadcast, selecting tapes from a central library, or dialing programs on a touch-tone device. However, the system is limited to 20 students, does not develop reading and writing skills, requires native speaker experts which are costly, and only experts can operate it.
