Abstract
Job requirements for Navy electronic technicians include extensive knowledge of basic electricity and electronics (BE/E) fundamentals. Historically the BE/E material has proved difficult for trainees to learn and has resulted in high setback and attrition rates. This study evaluates alternative computer-based instructional strategies for teaching complex technical content with 4 instructional conditions: computer-based drill and practice (CBDP), enhanced computer-based instruction (ECBI), a computer-based adventure game (GAME), and the existing classroom instruction (CI). We evaluated trainees on completion of the instruction with a schoolhouse comprehensive test, a specially designed cognitive skills test, and a motivation questionnaire. In addition, we recorded and analyzed the time participants took to complete the instruction. In general, the CBDP and ECBI groups outperformed the CI and GAME groups on all measures. The GAME condition performed no better than the CI condition. When differences existed between the ECBI and CBDP groups, the ECBI group performed better.
