The acquisition of multiplication facts by 4 elementary students with learning disabilities was compared under two instructional delivery formats-teacher directed and computer assisted. The two interventions were compared in terms of opportunities to respond and success rate. All students mastered more facts in the teacher-directed condition. In addition, teachers provided many more opportunities to respond and showed a higher success rate than did the software program. Implications of teacher-directed and computer-assisted instruction are discussed in terms of efficacy and feasibility.
