This report presents findings from a national survey on the extent of microcomputer use in elementary and secondary schools. The survey results indicate that: (1) in half of the schools with microcomputers, only one or two are regular users; (2) many teachers have become more than mere computer users and spend much time on programing; (3) in schools with microcomputers, one student in every seven uses the computer in an average week; (4) secondary schools are more likely to have microcomputers, and to have more of these, than elementary schools; (5) secondary school students have more access time to computers than elementary school students; (6) computer access time for students increases as schools get more microcomputers; (7) more computer time is used for programing than for drills and remedial activities; and (8) in elementary schools, drill and practice programs using computers function to increase students' understanding of the computer more than to teach subject matter and basic skills.
