A study examined the extent to which various individualized instructional methods were utilized in Navy "A" and "C" courses. During the study, questionnaires were mailed to instructors involved in teaching a random stratified sample of 623 Navy "A" and "C" school courses (a sample that represented 25 percent of the 2,491 such courses taught at the time). The instructors were asked to specify the amount of time that they utilized the following teaching methods: computer-aided instruction, computer-managed instruction, programmed instruction, self-paced instruction, direct student-instructor contact, and instruction involving the use of hands-on material. Based on data collected from the 445 usable questionnaires, the researchers concluded that the personnel involved in teaching the courses under investigation do not always classify the courses' methods of instruction in the same way that they are classified according to the Navy Integrated Training Resources and Administration System (NITRAS). Of the 414 courses in the study sample that were classified by NITRAS as group-paced, 50 were reported by the questionnaire respondents as having some self-pacing. This discrepancy in classification is due largely to the NITRAS self-pacing criterion for labeling courses as individualized instruction. To describe training courses more adequately, NITRAS should broaden its definition of individualized instruction. (MN)
