<![CDATA[Rapid advancements in hybrid vehicle technology demand significant adjustments in vocational education to equip students with relevant competencies. This study investigates the effectiveness of a hybrid motorcycle prototype as an innovative learning media to improve student learning outcomes in vocational automotive education. Employing a pre-experimental one-group pretest-post-test design, the research involved 30 Grade XI Automotive Engineering students at SMK Negeri 1 Cisarua. Participants underwent a pretest, followed by four prototype-based learning sessions, and a post-test. Data were analysed using descriptive statistics, paired-samples t-test, and normalized gain (g). Results demonstrated a substantial improvement in learning outcomes, with the mean score increasing from 58.5 to 82.67 (mean gain = 24.17 points; t(29) = 8.805, p < 0.001; Cohen's d = 1.61), indicating a very large effect size. The normalized gain of 0.55 suggests medium effectiveness based on Hake's classification. Furthermore, 90.0% (27/30) of students achieved scores ≥75 post-intervention, compared to 23.3% (7/30) beforehand. Aligning with Edgar Dale’s Cone of Experience, these findings highlight that direct, hands-on engagement enhances comprehension and retention. The study concludes that hybrid motorcycle prototypes offer a cost-effective, practical, and scalable solution to bridge the theory-practice gap in vocational automotive education, especially in motorcycle-dominant contexts. Recommendations include integrating prototype-based learning into the Merdeka Curriculum and expanding its application to other technical domains.]]>
