Improving Critical Thinking Ability and Learning Outcomes through Problem Based Learning Model for Mathematics Subjects in Fourth Grade

Abstract

This research aims to improve the critical thinking skills and learning outcomes of students in Mathematics subjects of KPK and FPB fourth grade. The research conducted was collaborative classroom action research using the Problem Based Learning learning model. The research was carried out in two cycles with four stages, namely planning, implementation, observation, and reflection. Data collection techniques used to determine critical thinking skills are tests in the form of essay questions and observations, while to determine learning outcomes using the same test given at the pre-cycle and at the end of each cycle. The data analysis technique uses qualitative description analysis.  The research subjects were fourth grade students totaling 27 students. The results showed that the application of the Problem Based Learning learning model can improve the critical thinking skills and learning outcomes of students in Mathematics subjects of KPK and FPB material in class IV. The research data on critical thinking skills showed an increase from pre-cycle activities which were originally in the low category, increasing to the moderate category in cycle I and high in cycle II. The learning outcomes of KPK and FPB materials for students also increased. Learners get scores above KKM 75, in the pre-cycle 37% to 67% in cycle I and 88% in cycle II.
