The attitudes of 90 enlisted personnel toward computer assisted instruction (CAI) were measured online before and after they received instruction presented by CAI. The instructional material was divided into four lesson segments, each followed by a review segment. Students who failed to reach the criterion score for any review segment repeated the corresponding part of the lesson, and a criterion test was administered at the end of the last segment. Measures of student performance used during the course of the instruction were (1) the total score on the criterion test, (2) the number of errors made during the lesson and review segments, (3) the percentage of responses made during the lesson and review segments that were incorrect, (4) the time required to complete the lesson and review segments, and (5) the number of review segments failed. Although the attitude pretest did not correlate with any of the performance measures, a correlation was obtained between attitude posttest and percent errors. Attitude change was correlated with total score, errors, and percent errors. Attitude and attitude change were not related to student ability. Appendices include summaries of the pretest and posttest results. (Author/CMV)
