Abstract

The level of understanding of students' learning in studying physics material deserves attention so that things do not happen that are not in accordance with the realm of concepts set by experts. The concept of physics is indeed fun to learn but it is enough to make students feel difficult when learning every material concept. The cause is the abstract concept of physics and its complicated mathematical calculations, especially in the matter of momentum and impulses. Although several studies state that misconceptions in studying physics concepts can be overcome, they do not last long and will definitely happen again. Therefore, this study aims to identify misconceptions among high school students regarding the concept of momentum and impulse. The research method used is descriptive quantitative. The participants in this study were 37 students who were obtained using a purposive sampling technique. The instrument used is the Three-tier diagnostic test which is formulated based on the indicators contained in the school curriculum used. The research data were obtained from the results of an analysis of the answers and patterns of students' answers on the three-tier diagnostic test items. The results of the study showed that it was identified that more than fifty percent of students had misconceptions.

Abstract

To effectively teach the complex concept of thermodynamics, appropriate and innovative teaching methods are needed to ensure a correct and in-depth understanding. This study aims to evaluate the application of the Problem-Based Learning (PBL) model in teaching thermodynamics to enhance students' comprehension of concepts and argumentation skills. The research utilized a quasi-experimental design with a pretest-posttest non-equivalent control group. Of the 50 participants, two distinct groups were formed through purposive sampling. A total of 27 participants underwent PBL instruction, while the remaining 23 participants received conventional learning instructions. The results revealed that students who were taught thermodynamics using the PBL model exhibited significant improvement in both conceptual understanding and argumentation skills compared to the control group. These participants displayed high engagement in tackling thermodynamic problems. PBL taught them how to argue comprehensively, emphasizing the cultivation of 'how to think' rather than just 'what to think' in addressing thermodynamic challenges. Based on these findings, this study recommends that physics educators consider incorporating PBL as a teaching strategy to bolster students' conceptual understanding and argumentation skills in thermodynamics.
