Abstract

The rapid development of technology requires education to participate in the use of technology as an innovation in learning. The purpose of this research is to develop and test a surface tension e-module based on Problem Based Learning in the Chemistry Physics course. The research method used in this study is Research and Design using the ADDIE development model which is limited to the analysis, design and development stages. The instrument used to determine the feasibility of the e-module is a questionnaire to test the validity of media experts and material experts. Respondents for testing the validity of media experts and material experts were educators in university and high schools. The feasibility level of the e-module is based on the validation of material experts by 80% which states that the quality of the material in the e-module is feasible from the material aspect and is based on problem based learning, the validation of media experts is 86.7% which states that the quality of the display on the e-module is very decent from the aspect of the media. This shows that the surface tension e-module based on problem based learning is feasible to use and implement in the learning process for university and high school levels.

Abstract

Chemistry learning, especially in Indonesia, has not been able to direct students to master critical thinking skills. Using appropriate media and learning models can improve students' critical thinking skills. One of the efforts to improve critical thinking skills is using Chemsketch media with STEAM-based learning models (Science, Technology, Engineering, Art, Mathematics). This study aims to analyze the effect of using ChemSketch in STEAM-based learning (Science, Technology, Engineering, Art, Mathematics) on improving students' critical thinking skills on chemical bonding material. This study used a Non-equivalent control group design. The population in this study were all grade X students of SMA Negeri 1 Karangwareng in the 2023/2024 school year, with the samples used including one class X-7 as the experimental class and one class X-6 as the control class. The data obtained were then analyzed using the N-Gain and simple linear regression tests. The results showed that: 1) STEAM-based learning significantly increases critical thinking skills with an N-Gain value of 0.66. 2) STEAM-based learning significantly affects critical thinking skills with a value of 0.002. It can be concluded from the results of this study that students in the experimental group experienced a significant increase in critical thinking skills compared to the control group. This indicates that integrating ChemSketch in STEAM-based learning can be an effective strategy to improve students' ability to analyze, evaluate, and solve problems related to chemical bonding.
