Abstract
This report reviews the literature on instructional graphics and implications of the findings in terms of graphic displays for computer-assisted instruction. It was concluded that (a) assumptions about the inherent value of graphics for instructional purposes are unsubstantiated by empirical evidence, and (b) the conditions under which the use of graphics may increase instructional effectiveness remain to be determined. Comparisons between alphanumeric and graphic displays, and between different graphic representations, suggest that future research should systematically explore the use of graphics as a function of task requirements, subject-matter content, and learner characteristics. The research also suggest that (a) the interpretation of research outcomes is contingent upon the dependent measures obtained, and (b) particular attention should be given to measures of delayed retention.
