Design and Development of a Cut-Away Differential Carrier Assembly Trainer

This research involved the creation of a cutaway model of a differential carrier assembly as an instructional tool to enhance practical learning among students in the Bachelor of Science in Autotronics program at the University of Science and Technology of Southern Philippines (USTP). The absence of adequate training materials has made it difficult for learners to fully grasp the function and mechanics of differential systems through traditional lectures alone. To address this, a physical trainer was developed to provide a hands-on, visual approach that would allow students to better understand the internal movements and relationships between components. The project followed the ADDIE framework covering the phases of analysis, design, development, implementation, and evaluation. Students and instructors participated in classroom-based testing and assessment. Findings indicated improved learner performance, interest, and comprehension. The study supports the integration of improvised, cost-effective training equipment as a means to improve the delivery of technical instruction in automotive education.
