Using a questionnaire, researchers surveyed 319 public high schools, each with fewer than 500 students, in 46 states to determine the extent and use of microcomputers in small high schools, to assess the use and users of correspondence courses in small schools, to identify the most frequently offered courses in small high school curricula, and to determine the need to add new courses. The majority of the schools (99%) had at least one microcomputer. The mean was 9.8 per school, or one computer for every 32.2 students. The schools used the computers most frequently for student instruction (especially in computer science, mathematics, and business courses), recordkeeping, and word processing. They reported that 21.4% of the teachers were computer literate and 45.4% were computer aware. Only 25% of school counselors frequently recommended correspondence courses to students needing additional credits. Most correspondence students were "D" or "F" students. The mean number of correspondence credits allowed towards graduation was 2.7. The four most frequently offered courses in small high school curricula were typing, English grammar, algebra, and biology. Principals felt they would most like to add courses in computer literacy, speech, word processing, computer programming, and remedial reading. (SB)
