Analysis of Students 'Mathematic Critical Thinking Ability Through Application of Problem Based Learning Models in Mts Hifzhil Qur'an Medan

Abstract

This study aims to analyze students' mathematical critical thinking skills through the application of a problem-based learning model. The research subjects of class VIII-5 MTs Hifzhil Qur'an Medan, totaling 39 students. The research instrument was a test of mathematical critical thinking skills and interview guidelines. Data analysis was performed using the Miles and Huberman model. The results showed that the students' mathematical critical thinking skills through the application of problem-based learning models obtained that out of 39 students there were 8 students who had high category mathematical critical thinking skills, 14 students who had medium category, and 17 students who had low category. For each indicator, students have an average assessment of interpretive indicators, namely the high category; analysis indicators, namely the medium category; evaluation indicators are low category; and inference is the low category. Student difficulties in completing tests of students' mathematical reasoning abilities a) in the high category, students have difficulty in the criteria of facts and principles; b) in the medium and low categories, students have difficulty in the criteria for facts, principles, and operations.
