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.

Abstract

Objective: One of the teaching materials that can increase students' interest and learning motivation is student worksheet with an interesting learning model. This study aims to: (1) train students' argumentation abilities when they want to express their opinions regarding chemical equilibrium material and (2) train students' self-efficacy by bringing opinions related to equilibrium material. Method: The research method refers to the 4D model, namely definition, design, development, and deployment. However, it is only limited to the third stage. The data collection technique used the validation method by three validators, namely two chemistry lecturers and one high school chemistry teacher. The instruments used to assess the validity of the student worksheet are content validity sheets and construct validity sheets. The data obtained is then processed using the agreement percentage formula. Results: student worksheet 1, student worksheet 2, and student worksheet 3 are feasible in terms of content and construction validity with very valid categories. This is evidenced by the agreement percentage value on each student worksheet which is above 75%. Novelty: student worksheet modeled on STEM-integrated ADI will be developed to train students' argumentation skills and self-efficacy. This novelty can be assessed as being able to provide: (1) solutions related to students' interest in ideas on chemical equilibrium material, especially the sub-factors of shifting factors towards chemical equilibrium and (2) being able to increase students' confidence when conveying their ideas or other actions.
