PENGARUH MODEL PROBLEM BASED LEARNING TERHADAP PEMAHAMAN KONSEP MATEMATIS SISWA

Abstract

Abstract: The Effect of Problem Based Learning Models to Increase Students’ Understanding of Mathematical Concept. This quasi-experimental research aimed to find out the effect of problem based learning (PBL) model towards students’ understanding of mathematical concept. The population of this research were all students of grade 7^th of SMPN 1 Terbanggi Besar in the even semester of academic year of 2018/2019 as many as 268 students that were distributed into nine classes. The sample of this research was students of class VII B consist of 29 students and VII C consist of  32 students who were selected by cluster random sampling. The design used was the randomized pretest-posttest control group design. Research data were obtained through an essay test on the social arithmetic. The data analysis used the mann-withney U test and  test. The result showed that the gain of students' understanding of mathematical concept through problem based learning model was higher than the gain of students' understanding of mathematical concept through conventional learning. Thus, problem based learning model has effect towards the student’s understanding of mathematical concept.
