Noting that this digest is only an indication of trends, not a detailed analysis, this report summarizes information on computer applications in primary and secondary education, including technical and vocational training, in 43 countries. The information was obtained from surveys made for differing purposes, monographs produced for various bodies, and reports prepared for meetings and conferences. The summary reviews the subject under two main headings: project policies and their economic considerations, and their educational significance. The first section discusses the existence and content of national policies on informatics, the institutional arrangements set up as a result of the policies, and the financial and technological investments that have been made. The second section deals with types of computer applications at the various educational levels, software and teacher training, and attempts to identify trends for each level of education--primary, secondary, technical, vocational, higher education, and informal education. The range of research activities reported is summarized under six headings: (1) Logo applications; (2) computers in special education; (3) general educational research; (4) subject teaching; (5) language teaching; and (6) computer processing of national languages. The third section, which constitutes over half of the report, presents summaries of data for the 43 countries studied, including data on the school population, educational budget, structure of the educational system, computer policies, computer applications, and research activities of each country.
