An 18-month project was conducted to adapt the resource room version of the National Center for Research in Vocational Education's Career Planning System (CPS) for delivery through microcomputers. Specific goals of the project were as follows: to adapt a print-based product previously found successful with middle school students who displayed mild forms of one of several disabilities, to evaluate the use of that adapted version with a representative sample of such students at sites across the country, to revise the materials on the basis of the evaluation results, and to initiate a plan for the national dissemination of the final revised version of the materials. After selecting the Atari 800 microcomputer system with 64K of random access memory as the delivery system for the revised version of CPS, project staff converted the instructional elements of the earlier version, along with management and record-keeping functions, into a 30-disk package. Various other printed materials, including instructor's and student's guides, were developed for use with the revised system. Based on the results of a field test of the revised CPS that was conducted at five sites throughout the country, it was concluded that middle school students from a variety of special populations found the system interesting, enjoyable, and usable. Students in the aggregated experimental group gained more knowledge concerning career planning than did students in the aggregated control group. Recommendations called for wide dissemination of the revised CPS among different populations at a wide range of grade levels. (MN)
