Application of Problem Based Learning Models with Realistic Mathematics Approach in Learning of Two Variables Linear Equations Systems

Abstract

The purpose of conducting this research was to find out the differences in student learning outcomes using the Problem Based Learning model with a realistic mathematical approach and the Problem Based Learning model with an Open-Ended approach to SPLDV material. This research is an experimental research, the design used is the Post-test Only Control Group Design. The subjects in this study, namely class VIII-A as the class experimental model that was applied was Problem Based Learning with a realistic mathematics approach with a number of 20 students and VIII-B was used as a class model that was applied, namely Problem Based Learning with an Open-Ended approach with a total of 20 students. both classes are homogeneous and equal. In this study, the data taken came from the post-test results in both classes. The average post-test score for the experimental class was 78.85 and the post-test average score for the control class was 73.05. The research results obtained based on hypothesis testing using the t-test with a significance level of 5% obtained the value t_count = 2.94 > t_table = 1.68 then reject  It can be interpreted that the learning outcomes of students who apply the Problem Based Learning model with the realistic mathematics is more than student learning outcomes that apply the Problem Based Learning model with an Open-Ended approach to SPLDV material.
