In October of the years 1984 through 1987, as part of the Annual School Program Survey, and primarily at the request of the Office of Instruction of the Los Angeles Unified School District (LAUSD), all elementary, secondary, and adult school principals were asked to provide information concerning computer usage at their schools. Results of the study indicate a significant increase in the number of microcomputers in the LAUSD, a trend which was reflected across all districts and at all levels. This produced a drop in the student per microcomputer ratio. However, because the extent to which individual computers are actually used varies, and because some units are used for office and administrative purposes, this finding should be interpreted with some care. Nevertheless, the variety of ways in which the computers are used also increased significantly. In particular, there appears to be a shift toward supplementing traditional applications such as computer programming and mathematics with uses that reinforce subject areas such as reading and language arts. Data on computers in the schools and computer applications are presented in 13 graphs and 64 tables, which are grouped by educational level and region. (2 references) (GL)
