This study compares an instructor-managed (IMI) and a computer-managed (CMI) version of a modularized, individualized Navy Training course; the main difference between groups was in testing and remediation. Subjects were 240 students enrolled in the Propulsion Engineering School at Great Lakes, Illinois, who were divided into three groups: CMI group, IMI-conventional (students followed normal school procedures and scored their own lesson tests), and IMI-control (instructors scored and remediated lesson tests). Dependent measures included: (1) module test scores for all three conditions, (2) lesson test scores for the IMI-control and CMI conditions, (3) comprehensive test scores for all three conditions, (4) time to complete the course for all three test conditions, and (5) time instructors spent on various activities. A 3 (groups) by 13 (modules) analysis of variance was performed on module test scores. There do not appear to be any major performance differences between the CMI group and the IMI groups. The course completion time data indicate that CMI does result in time savings; CMI also resulted in more free time and less test scoring for instructors. (VT)
