This fifth annual survey of computers and their use in South Carolina schools covers the 1978-88 school years. A questionnaire inventoried computer equipment and software, and dealt with such issues as instructional and administrative uses of computers, and availability of funding. The forms were distributed to all South Carolina public school (grades K-12) principals and district superintendents. Completed forms were received from 1,075 schools (97%) and 92 districts (100%). Highlights of the findings for schools include: (1) 97% of the public schools had computers for either instructional or administrative use; (2) 51% of the faculty members were rated as computer literate; and (3) the rate of change in the number of computers has slowed in the past two years. Major findings for districts indicate that all district offices have computers; Apple microcomputers are the most commonly used (39%); the total rate of change was 180% in 1985, 83% in 1986, and 61% in 1987; and 3.8% of all printers were laser printers. Detailed survey findings are presented in tables, charts, and graphs, together with brief descriptions of computer applications in individual schools and school districts. Brief reviews of eight special large scale computer projects conclude the report. (SD)
