The Paris Faculty of Science is developing programs in computer-assisted instruction (CAI). Their first goal is to develop "questionnaires" (instructional sequences) administered by teletype machines which check on a student's knowledge in an area and draw his attention to basic concepts, definitions, and theorems in that area. Using an IBM 360/30 computer, the research team has modified the basic hardware system and developed appropriate computer languages and software systems, which are described here. With this equipment, the teaching team has developed questionnaires for CAI in mathematics, physics, biology, and English (linguistics) for college undergraduates. The scope of these programs and steps in producing them are discussed. Revision of these programs is currently taking place. (JK)
