A Comparison of the Effectiveness of Several Feedback Modes for Correcting Errors in Computer-Assisted Instruction.
Hernandez, Ivan; Gilman, David Alan
This report presents the procedures, results and conclusions of a study designed to compare the effectiveness of several feedback modes for correcting errors in computer-assisted instruction. Seventy-five university upperclassmen were taught 30 general science concepts by means of a computer-assisted adjunct auto-instruction program. Subjects were assigned to five strata on the basis of scholastic aptitude; in each stratum, subjects were randomly assigned to one of the five treatment groups which differed only with regard to feedback modes. A treatment X level analysis of variance was performed to determine whether differences existed between any of the treatment groups with respect to any of several variables tested. Group means were not significant with regard to SAT scores, pretest scores, or the time required for subjects to attain the criterion of 30 correct responses. Results indicated that the most significant factor in the rate of error correction by adjunct auto-instruction is guiding the subject to the correct response. The most significant factor in immediate retention is the amount of feedback information the subject receives. Analysis of variance tables are included. (LC)
