Abstract

This research was motivated by the fact that the teaching materials used in physics learning are still largely dominated by conventional textbooks, teacher’s books, and Student Worksheets (SWS). The aim of this study is to develop guided inquiry-based Student Worksheets that can enhance students' critical thinking skills in the topics of temperature and heat. The developed Student Worksheets are expected to be not only valid in terms of content and structure but also effective in facilitating a more meaningful learning experience for students. This study employs a Research and Development (R&D) approach. The validation process was carried out by three physics lecturers from the State University of Padang (UNP). The analysis of the validation instrument results showed that the developed Student Worksheets obtained a validation score of 0.95, which falls into the "very valid" category. Therefore, the product developed in this study a guided inquiry-based Student Worksheet is considered valid and suitable for use as an innovative teaching material to improve students' critical thinking skills in understanding the concepts of temperature and heat.

Abstract

This research is driven by the students’ scientific literacy has not been well facilitated because the teaching materials used have not optimally supported its development. The purpose of this study is to develop and analyze the validity of the problem-based learning physics module intended to facilitate students’ scientific literacy. This study employed a research and development (R&D) method to develop and validate the module. The validation process was carried out by three physics lectures from the State University of Padang (UNP) and two high school physics teachers. Expert validation was carried out to assess six component: content feasibility, presentation, graphics, language, problem-based learning steps, and scientific literacy. Based on the data analysis, the developed module obtained a Aiken’s V index of 0.89, which falls into the valid category. Therefore, it can be concluded that the problem-based learning physics module developed to facilitate high school students’ scientific literacy is valid and appropriate for use as an innovative teaching material that effectively supports the physics learning process, particularly on the topic of climate change.

Abstract

Critical thinking skills are essential in facing the challenges of the 21st century, especially in physics learning, which requires analysis and problem solving. However, many students still find it difficult to develop these skills, especially in sound wave material, which is abstract and difficult to visualize. This study aims to determine the effectiveness of using PBL-based E-SWS in improving students' critical thinking skills. The method used is quantitative with a posttest-only control group quasi-experimental design. The research subjects were two 11th grade physics classes at SMAS Adabiah Padang: the experimental class used PBL-based E-SWS and the control class used conventional SWS. The instrument consisted of essay questions based on five critical thinking indicators. The results showed that the average posttest score of the experimental class was 73.984, which was higher than that of the control class, which was 63.083. The t-test showed that the t-count value of 2.167 was greater than the t-table value of 2.0003, with a significance level of 5%. These results indicate a statistically significant difference. It can be concluded that PBL-based E-SWS is effective in improving students' critical thinking skills in sound wave material.
