Designed to investigate the existing attitudes of students and instructors toward the computer managed instruction (CMI) learning environment, this research project also identified factors relating to these attitudes. Questionnaires were developed and administered to 100 instructors and 255 trainees from five schools taught under the CMI system. In general, trainee and instructor questionnaires contained items exploring attitudes toward the CMI system in the learning environment, demographics, interactions with instructors or students, and motivations. Response data were analyzed using descriptive and inferential statistics. Results of the study indicated that trainees' attitudes toward the CMI system in the learning environment were generally favorable, while those of instructors were generally not favorable. The study also revealed that trainees' length of service with the Navy appears to be related to attitudes toward the CMI system in the learning environment: the longer the trainee is in the service, the more negative the individual tends to be toward the system. Copies of the student and instructor questionnaires are appended and 13 references are listed. (Author/LLS)
