Pengaruh Model Pembelajaran Berbasis Masalah (PBL) Terhadap Kemampuan Berpikir Kritis Mahasiswa Kimia

Abstract

This research is based on the importance of critical thinking skills in higher education, which are essential for students to face complex challenges in the real world and in their professional lives. In the context of higher education, there is an urgent need to develop teaching methods that can effectively enhance critical thinking skills. Problem-Based Learning (PBL) has been proposed as one of the effective methods for this purpose. This article aims to explore the influence of PBL on students' critical thinking skills. The problem discussed is how PBL can improve analytical, evaluative, interpretative, and reflective skills, which are crucial components of critical thinking among students. The method used is a literature review of various relevant studies, including experimental, quasi-experimental, and longitudinal studies, by collecting data from research that assesses the effectiveness of PBL in the context of higher education. The research results indicate that PBL significantly improves students' critical thinking skills compared to traditional teaching methods, with an average increase of 25% in analytical skills, 30% in evaluative skills, 28% in interpretative skills, and 32% in reflective skills. Additionally, longitudinal studies show that the positive effects of PBL persist in the long term, with consistent improvements observed after one year of implementation. The conclusion of this article is that Problem-Based Learning (PBL) is an effective method to enhance students' critical thinking skills and prepare them to face complex challenges in the real world.
