The Effectiveness of Learning Design Based on Problem Based Learning Model Oriented Mathematicalcritical Thinking Skills of Fifth Grade in Elementary School

Abstract

This research is based on the low critical thinking skills shown by the low learning outcomes of students. The purpose of this study was to determine the effectiveness of learning design models based on Problem Based Learning in improving mathematical critical thinking skills of fifth-grade students in elementary schools. The research method used was quasi-experimental with a qualitative approach. The study population was all fifth-grade students of Elementary Schools in group 3 in Region II GedongTataan,Pesawaran. The research sample has 55 students and consisted of the fifth-grade student of Public Elementary School 5 GedongTataanas many as 27 students as the experimental class and the fifth-grade students of Public Elementary School 28 GedongTataanas many as 28 people as a control class. Data collection was carried out through a questionnaire and test of learning outcomes. Data analysis was performed using the acquisition of N-Gain. The results showed that the learning design based on the Problem Based Learning model was effective to improve students' mathematical critical thinking skills with the acquisition of N-Gain of 0.49.
