Evaluation of instructional software: Design considerations and recommendations

Abstract

The elements of desirable research design for the evaluation of educational technology are discussed with reference to the context of existing research. Sources of internal invalidity, type of compared educational activity, and outcome measures are considered. Finally, recommendations regarding the direction of evaluation research are made. Research designs that take into account the characteristics of the learner, the software, and the teacher preferably within the framework of a model of the learning process should be adopted. © 1993 Psychonomic Society, Inc.
