Development of a Customized Automotive-Electrical Trainer for Automotive Students at Samar State University

This study designed, developed, and evaluated a Customized Automotive-Electrical Trainer (CAET) for BSIT Automotive students at Samar State University. The trainer replicated essential automotive subsystems lighting, ignition, and charging circuits using locally sourced materials in a modular, safe, and flexible design. Fifteen students and three faculty evaluators assessed its functionality, usability, safety, and instructional effectiveness through Likert-scale instruments, observations, and interviews. Results indicated high performance across all criteria (overall weighted mean = 4.85, Excellent), with students reporting improved confidence in diagnosing faults and interpreting circuits. The CAET offers a cost-effective, hands-on instructional tool that bridges theoretical knowledge and practical skills.
