Pengaruh Model Problem Based Learning (PBL) Terhadap Hasil Belajar Mata Pelajaran Kelistrikan Pada Siswa TKR Kelas XI Di SMKN 1 Maros

The purpose of this study is to determine the effect of the Problem-Based Learning (PBL) model on learning outcomes in the Electrical Engineering course among 11th-grade TKR students at SMKN 1 Maros. This study is a pre-experimental study with a quantitative approach, utilizing a one-group pretest–posttest design. The research subjects were all 34 students in the 11th-grade TKR B class at SMKN 1 Maros. Data collection techniques included tests, observations, and documentation. Data analysis techniques involved descriptive statistical analysis and Normalized Gain (N-Gain) analysis. The research results showed that: (1) the implementation of the Problem-Based Learning (PBL) model reached 76.66%, falling into the “good” category; (2) the average student learning achievement increased from 62.35 on the pretest to 84.85 on the posttest, while the percentage of students meeting learning standards increased from 23.53% to 91.18%; and (3) the N -Gain analysis was 0.60, falling into the moderate category, indicating that student learning outcomes improved after the implementation of the PBL model, with the level of improvement falling within the moderate category. Thus, the PBL model had a positive impact on improving learning outcomes in the Electricity course for 11th-grade TKR students at SMKN 1 Maros.
