The purpose of this study was to determine the attitudes of students toward a computer managed instruction (CMI) biology course module and to check the internal consistency of the item banks on the test instrument. CMI as used in this study refers to the use of a computer to assist the instructor with routine management tasks in teaching such as testing, guidance, record keeping, and providing feedback to students. Specific areas addressed included whether: (1) students' attitudes toward CMI improved as a result of the experience; (2) students felt positive or negative about specific affective and operational aspects of CMI; and (3) whether improvements should be made in the item bank. Attitude scales (included in appendices) were administered to participants (N=64) on a pretest/posttest basis. Findings indicate an overall positive attitude change. Use of computer terminals did not appear to make students feel that instructors lacked concern toward their learning progress. Students favored immediate diagnostic feedback and opportunity to take tests at their convenience, considering CMI to be both a testing and learning experience. Correlation coefficients on total test and subscale internal consistency are reported with suggestions for improving the instruments. (Author/JN)
