Designed to aid teachers who are planning classes in the telematics mode, this checklist begins by reminding them that, in this mode, students cannot see them in the conventional sense, and classes are conducted using computer, telephone, modem, and microphone links. The checklist covers the following areas of concern: (1) the planning stage, specifically, practical and administrative checks; (2) situational and operational checks; (3) trouble shooting and back-up checks; (4) materials development; (5) the first few sessions, when the students are introduced to the teacher and the equipment; (6) practical lesson checks; and (7) student learning characteristics checks. The checklist also offers helpful hints about the technology used. (DB)
