Analysis of Effectiveness PBL-STEM to Improve Student’s Critical Thinking Skills

Abstract

Objective: This study aims to analyze the effectiveness of PBL-STEM in improving students' critical thinking skills. Method: The method used in this research is the literature review method. A literature review is a type of research that collects data and information from various sources by collecting and analyzing. This study analyzes as many as two national and international articles that can be accounted for. The articles used were published in 2018-2022. The steps in this Literature review method are identifying topics, searching for and selecting relevant articles, analyzing and synthesizing the literature, and creating a conclusion. Results: (1) the application of the PBL model can improve students' critical thinking skills; (2) the integration of STEM in the learning process is also able to improve critical thinking skills because STEM provides opportunities for students to identify real-life problems and solve them, which is per the characteristics of PBL; (3) the integration between PBL and STEM can be applied and can provide more effective results in improving students' critical thinking skills. Novelty: ThisThis study discusses the analysis of how effective the integration of STEM and PBL from the latest journals so that this research can be used as a reference for making quality learning tools.

Implementation of the PBL-STEM Model to Improve Students' Critical Thinking on Reaction Rate Material

“…There was an influence on students' critical thinking skills in the experimental class because the experimental class was given the treatment of applying PBL-STEM to make students more active and provide curiosity so that students can easily solve problems with their knowledge based on evidence and facts. STEM integration in the learning process can also improve students' critical thinking skills because STEM provides students with opportunities to identify real-life problems and find a solution, which is by the characteristics of PBL, so that the integration of PBL and STEM can be applied and can provide more effective results in improving students' critical thinking skills (Wahdaniyah et al, 2023). The PBL-STEM model, when applied with different learning delivery, can make students more enthusiastic when learning takes place.…”

“…Critical thinking is crucial for students since it enables them to solve social, scientific, and practical problems effectively. Thinking skills can boost students' critical analytical power (Nasihah et al, 2019;Purnamasari et al, 2020;Wahdaniyah et al, 2023). However, many students do not participate in teaching and learning activities properly, so when they are asked to conclude the material they have learned, they repeat several sentences about the material and cannot make conclusions.…”

“…Furthermore, students who will become the next generation must be knowledgeable with science, technology, engineering, and mathematics, as well as having critical and creative thinking skills, in order to fulfill the needs of the twenty-first century (Baucum & Capraro, 2021;Marlina et al, 2021). Based on this, this learning can be combined with the STEM method to support the success of PBL-based learning (Wahdaniyah et al, 2023). Students' critical thinking skills are very necessary and important to link science, technology, mathematics, and engineering in learning, so it is necessary to apply the PBL-STEM model to the subject of reaction rates for class XI SMA Kristen Sunodia Samarinda.…”
