Pengaruh Model Pembelajaran Problem Based Learning terhadap Hasil Belajar Biologi Siswa pada Materi Pencemaran Lingkungan

Abstract

Based on the results of observations and interviews, it shows that students' Biology learning outcomes are still low, characterized by student scores that are still below the Minimum Completeness Criteria (KKM), as well as students who are less enthusiastic in the learning process, especially on environmental pollution materials, so the Problem Based Learning learning model is applied. The Problem Based Learning learning model invites students to play an active role during the learning process by developing ideas through problem solving that has been provided. This study aims to prove whether or not there is an influence of the application of the Problem Based Learning learning model on students' Biology learning outcomes. This study uses a quantitative approach with the True Experimental Design method, this research design uses Posttest-Only Control Design, with the Simple Random Sampling technique. The number of samples in the study was 30 students in the instrument trial class, 37 students in the experimental class, and 37 students in the control class. Meanwhile, the data collection process used a test. Based on the results of the analysis, it shows that there is a significant influence, with a Sig.(2-tailed) value of 0.001 < 0.05, then Ha (alternative hypothesis) is accepted. Therefore, it can be concluded that there is an influence of the application of the Problem Based Learning model on students' Biology learning outcomes.
