Assisted Instruction Abstract In this paper the authors address some of the benefits to be derived through evaluation in the development and the dissemination of computer based instructional materials. Formative evaluation is discussed as a practical and worthwhile means of improving quality and effectiveness of instructional material. The importance of summative evaluation and documentation for intelligent selection and use of disseminated instructional material is discussed. Procedural suggestions are offered for employing both f o r m a t i v e a n d s,~mative evaluation within the context of systematic instructional design. An example is presented in which these suggested procedures were employed. Introduction One point of almost universal agreement among developers of computer-based instructional material is that the activity is time-consuming. Any discussion of barriers to widespread use of computer-based instruction is sure to include statements decrying the time required to develop good material, as well as the shortage of such material. Unfortunately, there seems to be reason to believe that the
