Abstract

This study aims to examine the increase in students’ understanding of the optical geometry concept after being given treatment using the discovery learning model assisted by PhET simulation media and to test the effectiveness of this learning model to improve understanding of the optical geometry concepts. The method used in this research is quasi-experimental and uses the research design The Static Group Pretest-Post-test Design. The sampling technique in this study was taken using purposive sampling, namely where the control and experimental classes were selected based on the suitability of the student’s character with the researcher’s goals. Each experimental and control group consisted of 35 participants. The experimental class used the discovery learning model assisted by PhET simulation media and the control class uses the conventional learning model. The instrument in this study was using a multiple-choice test of 20 questions. Based on the test results of the Independent Sample Test, it obtained a significance value (α = 0.0001 < 0.05), which means that there is a difference in increasing understanding of the optical geometry concept between classes using the discovery Learning model assisted by PhET simulation media using the learning model conventional.

Abstract

The structure of the vocational school curriculum is different from the structure of the high school curriculum in that the vocational school curriculum contains vocational subjects which causes students to set aside non-vocational subjects such as science. One of them is science subjects, whose role is unknowingly very important because the learning process prioritizes direct experience and does not become an important concern for students. The purpose of this study was to explore empirical data regarding the perceptions of vocational school students with the expertise of Fashion Design regarding the science learning process. So far, very few or even rare empirical reasons have been found for the perceptions of Vocational High School students of fashion skills regarding the science learning process. This research uses a type of case study research method with a quantitative and qualitative approach. The sampling process in this study used purposive sampling with participants totaling 37 students with an age range of 15-16 years. The instruments used in this study were questionnaires and interviews. The results of the study revealed that there were several different student perceptions in terms of interest, competence, effort, pressure, and values related to science learning activities in fashion design vocational schools.

Abstract

The rapid development of technology today does not only require problem solving skills, other thinking skills such as computational thinking skills are needed in solving complex problems. This study aims to investigate the relationship between problem solving abilities in physics, especially vibrations and waves, and computational thinking skills. This study uses a correlation research design in which the relationship between two variables of problem-solving ability and computational thinking is observed. By using data from 21 eighth grade junior high school students who had participated in wave learning, it was found that the correlation between the two variables was in the moderate category. These data indicate that problem solving abilities contribute to students' computational thinking skills. Discussion of the results of this study will be discussed in more detail in this article.

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.
