Abstract

Low creative thinking skills in automotive engineering learning can limit students’ ability to generate, adapt, and elaborate technical solutions. This study described the implementation of Problem-Based Learning (PBL) and examined changes in students’ creative thinking skills in the Fundamentals of Automotive Engineering course. A Classroom Action Research design was used with 21 Automotive Engineering students and conducted in two cycles consisting of planning, action, observation, and reflection. Data were collected using observation sheets on creative thinking indicators and analyzed descriptively based on creativity categories. In the pre-cycle condition, most students were classified as fairly creative (52.38%), while only 4.76% were very creative. After PBL implementation in Cycle II, the creative category increased to 47.62% and the very creative category increased to 28.57%, while the least creative category decreased to 0%. These findings suggest that PBL can support the development of students’ creative thinking in automotive engineering learning.

Abstract

Automotive education as a field of vocational education emphasizes the development of psychomotor skills through authentic and industry oriented practical learning. However, practical instruction in automotive workshops is often dominated by conventional teacher centered approaches, resulting in limited student engagement and suboptimal skill development. This study aims to analyze the effect of the Problem Based Learning (PBL) model on improving the psychomotor skills of automotive engineering students in practical learning. A quasi experimental method with a pretest–posttest control group design was employed. The research sample consisted of two classes of automotive engineering students from the 2025 cohort, selected using purposive sampling as the experimental and control groups. Psychomotor skill data were collected using a performance-based assessment instrument covering work procedure accuracy, tool operation skills, occupational safety, and the quality of practical outcomes. Data analysis was conducted using descriptive statistics and an independent t-test with a significance level of a = 0.05. The results indicate that students who participated in Problem Based Learning achieved higher average psychomotor skill scores than those who received conventional instruction. Hypothesis testing confirmed a statistically significant difference between the two groups (t_calculated > t_table). These findings demonstrate that Problem-Based Learning is effective in enhancing students’ psychomotor skills through contextual problem-solving activities, active learning engagement, and meaningful hands-on practice. This study provides empirical evidence supporting the implementation of problem-based instructional models in automotive vocational education and offers practical implications for improving the quality of practice-based learning aligned with industry competency demands.
