This report presents the results of the School Utilization Study (SUS) sponsored by the Center for Statistics and the Corporation for Public Broadcasting in 1982-83, which surveyed a sample of 2,700 teachers from schools across the nation to obtain information both on ways in which computers are being used by teachers in public and private schools, and on teachers' attitudes and opinions about the effectiveness of computers. To compare and contrast these findings, relevant information from outside studies is also summarized. The details of the findings are organized under: (1) "How Computers Are Being Used by Teachers," which summarizes most frequent usage by subject areas and grade levels; (2) "Teachers' Attitudes and Opinions about Computers," which cites teachers' desire for more training in computers, the need for more and better computer software, and problems with hardware and integrating the computers into subject areas; (3) "The Need for High Quality Software and Teacher Training," which indicates a need for more software in the areas of enrichment in specific subject areas, in computer literacy, and for challenging high achievers; and (4) "Methodology," which includes an overview of the study design and a discussion of the reliability of estimates of findings. Results of data analyses are highlighted in three tables. (DJR)
