This issue discusses the relevance of microcomputers to evaluation research and program evaluation. The relevance of software designed to aid in making decisions, establishing relations through statistical analysis, and gathering information is emphasized. The relevance of hardware, word processing, and teaching is also discussed. (BS)

Microcomputer simulations in evaluation research are useful for (1) improving student understanding of research principles and analytic techniques; (2) investigating problems arising in research implementations; and (3) exploring the accuracy and utility of novel analytic techniques. This article describes these simulation uses for the context of…

An evaluation plan using eight methods and triangulation of findings has been effective in evaluating the "Using Computer Visualization in Teaching Secondary Mathematics (Viz-Math)" project. Viz-Math enhanced the understanding and teaching practices of the 10 junior high and middle school and 34 senior high school teachers studied. (SLD)
