Designed to provide information for decision making when the current 5-year contract with the supplier of computing services to the Manitoba High School Computer Network expires in 1982, this study included both an assessment of the existing situation and the identification of alternative options for the provision of computer services to the schools. The initial section of the report provides a summary of the findings, operational definitions used, and the highlights, conclusions, and implications of each portion of the study. The remaining sections provide detailed reports on each of the five program objective-related facets studied: (1) support for school administrative services; (2) support for computer science and data processing courses; (3) the educational and manpower outcomes of the computer science and data processing courses; (4) support provided to other school services through the Program Library User's Manual (PLUM); and (5) the Computer Assisted Learning (CAL) Project for Special Needs Children and Adolescents. A discussion of the study of alternative means of providing computer services and brief descriptions of approaches used to support computer science and data processing instruction in Manitoba and elsewhere conclude the report. Appendices contain copies of the principal questionnaire, the computer-science/data processing teacher questionnaire and follow-up survey, the PLUM questionnaire, and two CAL questionnaires, one for teachers and one for parents and guardians.
