Analysis of High School Students' Critical Thinking Ability in Solving Mathematical Problems with Independence Problem-Based Learning (IPBL) Model: A Case Study on Middle Class Students

Abstract

This research aims to analyze the critical thinking ability of high school students in solving mathematical problems by implementing the Independence Problem Based Learning (IPBL) model. The research method was conducted through a case study involving high school students as research subjects. This case study was conducted on two 10th-grade high school students at SMA Negeri 1 Paguyangan, Brebes, Central Java. The instrument used to measure critical thinking ability was a written test adapted to the context of mathematics. The results showed a significant improvement in students' critical thinking abilities after participating in learning with the IPBL model. Discussion of the results highlights the importance of the IPBL model in enhancing students' critical thinking abilities and its implications in the context of mathematics learning at the high school level. These findings contribute significantly to our understanding of the effectiveness of the IPBL learning model in improving students' critical thinking abilities, as well as demonstrating its relevance in the context of more effective and in-depth mathematics learning at the high school level.
