This study examined the effectiveness of the Motorcycle Engine Trainer as an instructional tool in enhancing the learning outcomes of Grade 9 students enrolled in Motorcycle and Small Engine Servicing. Conducted at Carrascal National High School and Parang National High School in Surigao del Sur, the study employed a quasi-experimental design with pre-test–post-test control groups. A total of 100 students participated, divided into experimental and control groups, with the former taught using the Motorcycle Engine Trainer and the latter through conventional lecture-demonstration methods. Findings revealed that while both groups initially demonstrated comparable low mastery, the experimental group showed significantly greater improvement in the post-test. Independent samples t-test analysis confirmed a statistically significant difference in performance between the two groups, favoring those taught with the Motorcycle Engine Trainer. These results underscore the pedagogical value of hands-on, technology-enhanced instruction in strengthening conceptual understanding and practical skills in technical-vocational education. The study concludes that integrating functional learning aids such as the Motorcycle Engine Trainer can effectively bridge the gap between theoretical instruction and practical application. These findings hold important implications for educators, curriculum developers, and policymakers, highlighting the need to adopt innovative instructional tools to improve competence, engagement, and industry readiness among students in technical-vocational programs.
