A Comparison of the Effectiveness of Feedback Modes for Teaching Science Concepts by Means of a Computer-Assisted Adjunct Auto-Instruction Program.
Gilman, David Alan
Seventy-five university upperclassmen were taught 30 general science concepts by means of a computer-assisted adjunct auto-instruction program. Treatment groups differed only with regard to feedback modes. The five modes compared were Group A (no feedback), Group B (feedback of "correct" or "wrong"), Group C (feedback of the correct response choice), Group D (feedback appropriate to the student's response), and Group E (a combination of the feedback modes of Groups B, C, and D). Subjects were assigned to 15 strata on the basis of scholastic aptitude. The five subjects in each strata were randomly assigned to one of five treatment groups. Analysis of variance was performed to determine whether differences existed between any of the groups with respect to several variables tested. The means of groups guided by feedback to the correct response (Groups C, D, E) were significantly better than the groups required to "discover" the correct response. No differences were found between subjects and their attitudes toward computer instruction, and no relationship was found between scholastic aptitude and any of the variables studied. (BC)
