Analysis of responses to the development of e-modules to improve students' critical thinking skills in reaction rate materials in the form of android applications

Abstract

Students' critical thinking skills in chemistry learning are generally still low, so interesting teaching materials are needed to improve students' critical thinking skills, one of which is the e-module. This study aims to determine the feasibility of the e-module and to determine the response of educators and students to the android application-based e-module in improving students' critical thinking skills on the material of reaction rate. The method used in this study is the research and development (R&D) method. The sample used was 15 students. The research instruments used were validation questionnaires for material experts and media experts, assessment questionnaires for educators and student response questionnaires. Data analysis techniques used are quantitative and qualitative. Based on the research results it is known that the product in the form of an e-module on the reaction rate material is suitable for use in learning. The results of the analysis of student responses also showed high student interest in the developed e-module.
