The effect of implementing project-based learning on conceptual understanding of electrical engineering subjects in vocational high schools

This study aims to investigate the effect of implementing Project-Based Learning on the conceptual understanding of electrical engineering subjects at Bhakti Samudera Vocational High School. This study used a quasi-experimental design involving 56 students who were randomly selected from the same school. Before the intervention, a pre-test was carried out to measure students' initial understanding of the concepts of electrical engineering subjects. Furthermore, students were divided into two classes: the experimental class and the control class. The allocation process ensures that relevant characteristics, such as age and grade, are similar between the two classes. Statistical analysis using a paired sample t-test confirmed the significance of this finding. The t value is -2.151 and the Sig value (2-tailed) is 0.041, indicating a significant difference between the experimental class and the control class in understanding the concept of electrical engineering subjects. This shows that the application of project-based learning affects students' understanding of concepts in electrical engineering subjects. However, it is important to be aware of some limitations in this study. The research was conducted in one school with a limited sample, so the generalization of the findings needs further investigation. Further research is needed to explore the factors that influence the effectiveness of project-based learning in different educational contexts. Further research and application of project-based learning in various educational contexts are recommended to continue exploring its potential for improving learning outcomes and preparing students to face future challenges in the era of globalization.
