Abstract

This study aims to determine the effect of applying the Problem Based Learning (PBL) learning model using video media on the learning outcomes of seventh grade junior high school students on environmental pollution material. This research was conducted using a quasi-experimental method. The population of this research is class VII SMP Negeri 11 Medan T.A 2021/2022. The research sample consisted of 2 classes. The data were analyzed by calculating the average obtained by students after receiving treatment. The data were analyzed by calculating the Normality Test, Homogeneity Test and Hypothesis Testing. The average results of the pretest and posttest tests for the experimental class were 46.87 and 80.09, respectively, which were higher than the average test in the control class for pretest and posttest data, which were 41.76 and 72.33. The results of hypothesis testing using the t-test method (independent t-test) student learning outcomes obtained that tcount > t table that is (3,947 > 2,000). So, it can be concluded that there is an effect of the Problem Based Learning (PBL) model on student learning outcomes regarding environmental pollution in class VII SMP Negeri 11 Medan T.P 2021/2022.
