The data presented on microcomputer usage in the Oklahoma public schools are based on a 37.5 percent response to a survey mailed to the 1,785 school building principals in the state. The results are reported separately for elementary, middle, and secondary schools, including numbers of microcomputers with brand name and model, peripheral devices, and department assignment. Grade level, subject area, and program source are listed for both commercially and locally-developed software programs in use. Also provided is information on the types of problems schools are experiencing in using microcomputers, their plans to acquire additional equipment, school personnel's interest in a career guidance software package, personnel who need more training, and the type of training desired. This survey is to be the basis for activation of a microcomputer section, including a technical center, in the Oklahoma State Department of Education. (LMM)
