An explanation for the failure of technology and computer-assisted instruction (CAI) in particular to make much headway in education is that even when innovations are introduced in the classroom, their potentials are not exploited; rather, they are used in traditional ways. The integration of new technologies with other classroom activities is also necessary to realize any advantages. This has not generally been done. Experience with CAI in the chemistry department at Simon Fraser University in British Columbia began in 1969. An interactive program was developed to review basic problem sets with first year students. This program was used in conjunction with explanatory audiotapes. A second drill and practice series was also developed. The materials made little difference in student performance until the traditional structure of the course was changed. The chemistry department gained significant experience with hardware and course development. They exchanged IBM's Coursewriter III system for York/APL which in turn they abandoned for IBM's APLSV which still was inadequate for authoring and delivering CAI. Eventually the department developed its own authoring language which reflected the needs perceived in six years of CAI experience. A 17 item bibliography is appended to the report. (KB)
