To better understand the instructional computing needs of Iowa's K-12 teachers and administrators, a needs assessment was conducted in the spring of 1983. A 48-item administrator questionnaire and a 52-item teacher questionnaire were used to gather data from all Iowa school superintendents and from random samples of both elementary and secondary teachers. Results indicate that both the teachers and the administrators felt positive and enthusiastic about all aspects of instructional computing. They perceived a need for inservice instruction as well as for using the computer in classroom instruction and management. Both teachers and administrators felt that preservice teachers should learn programming and techniques to evaluate, select, and use appropriate software. Differences emerged between administrators' and teachers' perceptions of teacher needs, and elementary and secondary teachers differed on specific items concerning the usefulness of various computer assisted instruction modes and of various computer management techniques. Significant differences also existed among five secondary teacher groups (humanities, mathematics and science, physical education, vocational education, and special education), suggesting that certain groups favor computer applications unique to their discipline. Finally, teachers and administrators warned educators against making the computer a panacea for all educational woes. The survey instrument and 77 data tables are included. (LMM)
