Abstract
Educational technologies include many types of instructional systems. Individually Prescribed Instruction, a pencil and paper instructional system, offers opportunities for computer applications. Research for Better Schools and the Philadelphia School District have, for the past sue years, combined jointly in such efforts.

It appears that large time-sharing systems are not going to provide such cost-effectiveness. However, research and development of small stand-alone systems offer real possibilities for reaching this goal.
