Douglas Carnine is associate professor of special education at the University of Oregon. Current research on instructional design variables covers the computer, videodisc, and teacher as delivery medium. The study evaluated the role of instructional design in the field test and revision process for computer assisted instruction (CAI) in drawing conclusions and critiquing syllogistic arguments. Secondary resource room students were randomly assigned to either the original CAI program or the revised program. Measures included posttest scores, time to completion, and error rates. Scores significantly favored students in the revision group who made fewer errors per lesson, took less time to complete the lessons, and had higher posttest scores on the criterion-referenced test. Instructional design principles that guided the revision process are discussed.
