This paper reviews the research literature on relationships between the integration of microcomputers and students' learning of mathematics in secondary schools. Following a brief introduction and statement of the problem, annotations are provided for 31 studies in the following subject categories: (1) the extent of computer use in secondary schools in the United States; (2) computer-assisted instruction/computer-assisted learning; (3) computer integrated instruction; (4) student attitudes; and (5) faculty and administrator attitudes. Summaries of the research in each of the five categories are provided, and conclusions and recommendations are made concerning training, administrative leadership in integrating computers into the curriculum, opportunities for students to use microcomputers, and the need for computer resource personnel and further research.
