Improving Students’ Critical Thinking Ability through Model-Based Learning (PBL) in Mathematics Learning in Class V of Golo Elementary School

Abstract

This article discusses the effectiveness of the problem-based learning (PBL) learning model in improving students' critical thinking skills. With this learning model, students can learn to solve problems using their existing knowledge. Problem-based learning, or PBL, is an approach to the teaching and learning process that uses a real-life problem as a context for exploring critical thinking knowledge. The research was conducted in the form of Classroom Action Research (CAR) using the Kemmis model research design. and Mc. Taggart. The research was conducted in SD Negeri Golo. Twenty-five grade V (five) students participated in the study. In the pre-cycle, before the introduction of problem-based learning (PBL), they showed critical thinking skills with a classical completeness of 46% and an average of 68.5. In cycle I, after the introduction of problem-based learning (PBL), they showed an increase in critical thinking skills with a classical completeness of 62% and an average of 68.05. In contrast, in cycle II, the classical completeness score was 83% with an average score of 75.2. The problem-based learning (PBL) model as a whole can improve students' critical thinking skills, which has an impact on improving students' learning outcomes in the learning process.
