This paper reviews research conducted at the Institute for Social Research at the University of Michigan for the Agency for Instructional Technology as part of "Solutions Unlimited," eight instructional units that integrate computer software, videocassettes, and related print materials. The units are designed to improve the problem-solving skills of students in grades 6, 7, and 8, and to make them familiar with the problem- solving applications of computers. This report on microcomputer use in the middle school summarizes the findings of a national survey (Henry Becker, 1983) and supplements it with case studies of five schools that typify the varieties of use. The focus is on the present--how micros are being used today--and the future--what the teachers and principals think about current applications and what they think will happen in the coming years. An outline of a videotape showing how microcomputers are used in middle schools and guides for principal and teacher interviews are appended. (Author/JB)
