ABSTRACT
Vocational education aims to develop performance (psychomotor) skills in addition to knowledge (cognitive skills) and attitude (affective skills). This study aimed to improve the competence of vocational students majoring in Mechanical Engineering in Computer-Aided Design (CAD) using Project-Based Learning (PBL) modules. The study adopted the Research and Development (R&D) method of Four-D Thiagarajan in four stages (define, design, develop, and disseminate). The CAD module was validated by CAD experts, design experts and linguists. The module was tested on students by conducting post-test performance and obtaining students’ responses when applying the module. The research results indicated that the CAD module was viable, with an average validation score of 90%from CAD experts, design experts, and linguists. Based on the results of module testing, 91.33%of students considered that the module was good, while the results of testing student performance showed improvement in the vocational students’ competence of 88%for the psychomotor skills domain and 80%for the cognitive domain.
