However, the evaluations done to date simply do not support the program's effectiveness at improving young children's reading achievement. (MLH)

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…
