User involvement in the development and use of computer based systems for the health and rehabilitation sciences: reducing protocol test errors.
In this study an attempt was made to clarify conflicting results in the learner control literature. The learner control concept was redefined in order to include both choice and self investment variables. The combined effects of choice and self investment variables were considered in this study to be motivational variables which affect the learner's attitudes and performance on a computer assisted instructional task. The results of this investigation indicated overall differences in performance among treatment groups. An interaction effect between choice and self investment was found for the performance measure. The expected interaction and perceived control measures were not found. Various analyses of the postexperimental test protocol scoring errors were conducted in order to investigate the effectiveness of the computer assisted instruction (CAI) task. Completion of the CAI task seemed to decrease the number of scoring errors made on subsequent test protocols as compared to those who did not use the CAI task. Implications for the health and rehabilitation sciences are discussed.
