PENGARUH MODEL PROBLEM BASED LEARNING (PBL) TERHADAP KEMAMPUAN BERPIKIR KRITIS MATEMATIS SISWA

Abstract

The purpose of this research are: (1) to know mathematical critical thinking ability of students who follow learning with model of Problem Based Learning (PBL) is higher than students who follow conventional learning, (2) to know student response to model of Problem Based Learning (PBL) during learning takes place. This study included a quasi-experimental type of study. The result of the research shows that students' mathematical critical thinking ability which follows learning model with Problem Based Learning (PBL) is higher than students who follow conventional learning. Based on hypothesis test obtained tcount = 2.59 and ttable = 1.672 with dk = 58 and significance level so that it looks that tcount = 2.59 > ttable =1.672. The result of student's questionnaire analysis shows that student's response is positive to Problem Based Learning model, which means that students are motivated in learning by using Problem Based Learning model. So, it can be concluded that the model of Problem Based Learning effect on students' critical thinking skills mathematically.
