Abstract

Technological developments have led to innovations in teaching materials such as the development of electronic books (e-books). In physics subjects, e-books need to be developed and used optimally to support learning. This research aims to determine the effectiveness of using physics e-books assisted by PhET interactive simulation based on problem-based learning in improving students' critical thinking skills on global warming material in modeling and implementation classes. This research is a quantitative research with a quasi-experimental research design with one pretest and posttest group. The subjects in this research consisted of 32 modeling class students and 23 implementation class students who were obtained using cluster sampling techniques. The data collection technique used is a test and the data analysis technique is the N-Gain test. The research results show that the use of physics e-books assisted by PhET interactive simulation based on problem-based learning on global warming material has an impact on increasing students' critical thinking abilities. Then, the use of physics e-books is quite effective (in the medium category) in improving students' critical thinking skills in modeling and implementation classes. The use of e-books in physics learning makes students more interested in learning so that it has an impact on students' thinking abilities.

Abstract

One of the important skills that must be mastered in 21st-century learning is communication skills. The facts show that students' communication skills in learning physics, specifically on the topic of global warming, are still low. This research aims to determine the feasibility and effectiveness of the global warming e-book based on problem-based learning (PBL) assisted by PhET interactive simulation to improve students' communication skills. The type of research used is pre-experimental, with a one-group pretest-posttest research design. The sampling technique is cluster random sampling, the modeling class and the implementation class are randomly selected. This research was conducted on 55 students in class X of high school, consisting of 32 students in the modeling class and 23 students in the implementation class. Data collection techniques are carried out through validation and pretest-posttest. The validation data to determine the feasibility of e-books and communication ability test instruments were analyzed using the V 'Aiken equation. The effectiveness was analyzed using the N-Gain test and to determine the significance of the increase using the ANOVA test with eta squared (effect size) analyzed with the SPSS program. The results of the study show that the validity of the e-book is on very good criteria, so it is worth using. The results of the N-Gain test of the modeling class and the implementation class showed that the use of e-books was quite effective in improving students' communication skills, with an impact size of 0.406 in the modeling class and 0.519 in the implementation class. So, this global warming e-book can be used by physics teachers in physics learning. The limitations of this study include the use of subjects limited to only two classes and restricted time allocation. Therefore, future research is expected to conduct studies on a larger scale and consider time allocation when selecting the learning model.
