Abstract

This study aims to: (1) analyze the implementation of the Project Based Learning (PjBL) model in improving students' learning outcomes in the subject of Manufacturing Technical Drawing in Grade XI of vocational high school; (2) analyze the improvement of student competencies in the subject through the application of the Project Based Learning model; and (3) analyze the increase in student activity, engagement, and participation during project-based learning.This research employed a Classroom Action Research (CAR) method.The research subjects were 33 students from Class XI TP 2 at SMK Negeri 2 Yogyakarta who had experienced learning through the Project-Based Learning model. Cognitive learning outcomes data were obtained through multiple-choice tests, while skills data were collected using observation sheets assessing students’ practical performance. Data analysis was conducted using both quantitative and qualitative approaches.The results showed that: (1) the PjBL model was effective in improving students' learning outcomes, as evidenced by the increase in the average score from 74.09 in the pre-cycle to 77.52 in the third cycle, and the improvement in learning mastery from 55% to 91%. (2) Student competencies improved gradually, in terms of conceptual understanding, project completion, and contextual application of knowledge. (3) This model also succeeded in enhancing student activity and engagement, as indicated by the increase in average activity scores from 74.09 and engagement level of 55% in the pre-cycle to 77.52 and 91% in the third cycle.
