Abstract

The study aims to develop an acid-base e-module based on guided discovery learning using React Native to improve the problem-solving skills of senior high school students. The research method is Educational Design Research (EDR) using the Plomp model. The e-module using React Native is presented in the form of a mobile application that can be accessed on smartphones. The presentation of acid-base material in the e-module is adapted to the syntax of Guided Discovery Learning. The e-module was validated by 5 validators, including 3 subject matter experts and 2 media experts, using a questionnaire analysed with Aiken's V. Practicality was assessed by 9 students representing low, medium, and high ability categories using a questionnaire in the small group stage, analysed using achievement percentages. Effectiveness was determined by comparing pre-test and post-test scores of students using the N-gain formula. The validation results of the acid-base e-module using React Native were 0.90, categorized as valid, and the practicality of the e-module was 92%, categorized as highly practical. Effectiveness was obtained from N-gain data of 0.71, categorised as high (sufficiently effective). Hypothesis testing was conducted using the Wilcoxon test because the data was not normally distributed, with a sign of < 0.001, indicating that the acid-base e-module based on guided discovery learning using React Native can improve the problem-solving skills of senior high school students in phase F.

Abstract

This study aims to develop a chemistry learning module based on the discovery learning model on chemical kinetics material to improve critical thinking skills of grade XI Phase F high school students. This research is a type of development research (Research and Development) that uses the Plomp development model, which consists of three stages: preliminary research, development (prototyping phase), and assessment phase. The preliminary research stage includes needs analysis and theoretical studies as the basis for compiling the module. Furthermore, in the development stage, the module was validated by five experts to assess the feasibility of content, presentation, language, and contextual aspects. The results showed that the developed module had very high validity with an average Aiken's V value of 0.96. The practicality test showed an average value of 98.50%, which is classified as very practical. The effectiveness test produced a significance value of 0.019 (< 0.05), which indicates a significant increase in learning outcomes after using the module. It can be concluded that this discovery learning module on chemical kinetics is valid, practical, and effective in improving students' critical thinking skills. This module can be an alternative contextual teaching material that encourages active and independent learning at the high school level.
