The effect of problem based learning (PBL) on students’ critical thinking

Abstract

This study aims to determine the effect of Problem Based Learning (PBL) Learning Model on Students' Critical Thinking Ability in Mathematics Class V SDN Banjarejo, Madiun City. This research is a quantitative research with experimental method. The population of this research was all students of VA class at SDN Banjarejo, Madiun city, with sampling technique using saturated sampling with 27 students while the research design used One Group Pretest-Posttest Design. Based on the results of hypothesis testing with the t test (t-test) shows that t-count = 50> t-table = 1.705 then H1 is accepted meaning by using the Problem Based Learning (PBL) learning model the students' critical thinking skills become better. From the calculation of students' critical thinking skills showed that 3 students with low critical ability, 12 students are moderate, and 12 students with high critical ability. It means that the Problem Based Learning (PBL) learning model influences students' critical thinking abilities.
