The Hawaii State Department of Education offers university credit courses in English-as-a-Second-Language (ESL) techniques to all public school teachers, but the scarcity of trainers and the distance between schools and training sites constitute substantial obstacles. With the cooperation of the University of Hawaii's interactive television system, many teachers are now being trained through distance training (DT). This paper describes three models of in-service teacher training in distance education at three levels of interactivity. The most interactive of the models is closed-circuit TV with two-way audio and video, although not all sites have these facilities. The second model is two-way audio and one-way video. The third approach is to provide the course over cable TV on a public access channel. In all models, as the direct contact between the trainer and the teachers is attenuated, there is increasing need for the trainer to structure the class so that the teachers are kept active and involved. A description of the Hawaii Interactive Television System (HITS) is appended. Contains 20 references. (Adjunct ERIC Clearinghouse on Literacy Education) (Author/LB)
