PENGARUH MODEL PROBLEM BASED LEARNING TERHADAP HASIL BELAJAR SISWA PADA MATERI GETARAN DAN GELOMBANG DI KELAS VIII SMP SWASTA PAHLAWAN NASIONAL

Abstract

This study aims to determine the effect of Problem Based Learning model on student learning outcomes on vibration and wave material in class VIII of Pahlawan Nasional Private Junior High School, totaling 181 students. Then given different treatments experimental class with Problem Based Learning model and control class using conventional model. The average posttest results obtained by the experimental class were 68.53 and the control class was 56.31. Furthermore, the data was analyzed by normality test and homogeneity test. After the data from the pre-test and post-test were normal and homogeneous. Furthermore, the post-test data in the one- party t test obtained tcount > ttable (1.921>1.671). Then Ho is accepted and Ha is rejected. Thus the data shows that the Problem Based Learning model has an effect on student learning outcomes on vibration and wave material in class VIII of Pahlawan Nasional Private Junior High School. The calculation of the g factor (N-Gain) of 0.74 shows a high category which means it is effective and seen from the calculation results it can be concluded that there is an increase in student learning outcomes after using the Problem Based Learning model in class VIII of Pahlawan Nasional Private Junior High School.
