This article describes efforts to include an expert system software package, based on the theories of B. F. Skinner, into a computer managed instructional system. The purpose of the system is to provide meaningful feedback to students concerning their achievement status on a weekly basis. The process for the development of the system is discussed as well as results in light of the collection and analysis of both quantitative and qualitative data. Conclusions are drawn that suggest that behaviorist techniques can be incorporated into instructional software at a level higher than the traditional task specific feedback.
