Abstract

This study investigates the effect of Project-Based Learning (PjBL) on students’ cognitive understanding and psychomotor performance in the Computer Aided Design (CAD) subject, a core course within the Mechanical Engineering program at SMKN 1 Singosari. The research was motivated by the need to bridge the gap between theoretical instruction and real-world design competencies in vocational education. A quantitative descriptive approach was employed, with a total sampling technique involving all students enrolled in the CAD course during the ongoing semester. Data were collected through cognitive tests, practical performance assessments, and Likert-scale questionnaires to measure perceptions. The results revealed that students achieved high levels of cognitive mastery, with dominant correct responses on key CAD concepts such as part modeling, assembly environments, and technical file formats. Psychomotor evaluations indicated consistent practical performance, with a mean score of 82.36, while perception analysis reflected high levels of student engagement and satisfaction with the PjBL model. These findings suggest that PjBL effectively fosters integrated learning experiences that enhance technical understanding, practical skills, and student motivation. Consequently, the adoption of project-based strategies is recommended for vocational curricula to support competency-based education in technical fields.

Abstract

Vocational education must ensure that students acquire not only technical competence but also the confidence and critical thinking needed for real-world tasks. This study investigates the effectiveness of a mentor-based instructional model in enhancing student performance in Shielded Metal Arc Welding (SMAW) practices within the subject of Creativity, Innovation, and Entrepreneurship at SMK Negeri 1 Singosari, Indonesia. Using a descriptive quantitative approach, data were collected from 70 eleventh-grade mechanical engineering students through structured performance assessments and Likert-scale questionnaires. The results show a high average performance score of 84.04 with a standard deviation of 3.18, where 89% of students were categorized as “High” and 11% as “Very High.” Performance scores increased progressively across assessment stages, and students reported improved confidence, motivation, and procedural accuracy. These findings suggest that structured mentoring significantly supports technical mastery, reduces skill disparities, and cultivates reflective learning habits. It is concluded that mentor-guided learning should be integrated more widely in vocational curricula. It is also recommended that future research explore the long-term impact of mentoring on work readiness, creativity, and entrepreneurial mindset across other technical fields.
