Computer applications in South African schools are described in this five-paper collection of journal articles, which covers a range of projects from primary school and university elementary arithmetic to more sophisticated applications in physics, chemistry, and biochemistry. "Implementation of a System of Computer-Assisted Instruction in Arithmetic in Black Primary Schools in South Africa" (T. P. Metrowich and J. J. D. Roux) discusses the implementation of the TOAM system (a Hebrew acronym for test and practice) at five primary schools. In "Computer-Assisted Learning in the Primary School: A South African Example," P. Waker describes microcomputer use at the Sea Point Boys' Primary School in remedial spelling and enrichment programs. "Microcomputers, Conceptual Change and the Design of Science Instruction: Examples from Kinematics and Dynamics" (Peter W. Hewson) explores use of the microcomputer to address students' alternative conceptions of physical phenomena through diagnostic and remedial programs. The role of the computer in education is addressed by J. D. Bradley, G. Brink, and L. Glasser in "CAI: A Report to the Academy." In "Computer-Managed Instruction on the PLATO System," G. R. Delpierre explains use of the PLATO Learning Management System at the University of the Western Cape. All papers list references. (LMM)
