A study was conducted to refine a model Computer-Managed Information System (CMIS) that provides learning prescriptions based on students' learning styles and to identify specific problems concerning its implementation in other time-sharing environments. During the 1974-75 academic year, the CMIS that was constructed and tested the previous year at the University of Wisconsin-Stout was developed and refined. Visits with personnel in two vocational technical and adult education districts, and other contacts, revealed that considerable differences in computer software and stages of development of computer usage would restrict the implementation of the model. Efforts to promote the management of instruction based on learning styles should proceed according to the unique constraints at each computing environment and should include an initial emphasis on information storage and retrieval. The report includes objectives for an inservice course for teachers, a list of references, and a sample of the output from the system. (Author/RG)
