Abstract

This study aims to produce teaching materials in the form of e-modules based on a contextual approach with a REACT (Relating, Experiencing, Applying, Collaborating, Transferring) strategy on acid-base materials.This development is a type of EDR (Educational Design Research) research with a plomp research model. Lecturers and teachers act as expert reviews, and 9 students become research subjects in this development research. The data obtained in the form of content validity, construct, linguistic and graphic data were processed using the AIken's V formula, while the practicality data was processed using practical percent. Based on the results of the study, the V value for content validity was 0.84, construct validity was 0.83, linguistic validity was 0.84 and graphic validity was 0.87, which were included in the valid category. Then the practicality results show a value of 90% with a very practical category and the results of the effectiveness test show that e-modules can improve student learning outcomes Keywords: e-modul, contextual approach, REACT learning strategy, acid baseDOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp266-275

Abstract

The current condition of the Covid-19 pandemic is very influential on the learning process in schools so that a teaching material is needed that can increase the activity of students. This study aims to develop an e-module of colligative properties of solutions based on Guided Discovery Learning to improve Higher Order Thinking Skills (HOTS), as well as determine the level of validity, practicality and effectiveness of the developed e-module. This research and development uses the Plomp model which consists of 3 stages. The assessment instruments used are observation sheets, questionnaires, and learning outcomes tests. The e-Module was validated by six expert validators and tested on six students and 36 students at SMAN 14 Padang. The validity results of the e-module obtained an average value of Aiken's V of 0.84 with a very valid category. The results of e-module practicality by teachers and students obtained an average score of 0.90 and 0.88 with a very practical category. The results of the e-module learning effectiveness test obtained an average N-gain value of 0.691 with a moderate category Keywords: e-module, guided discovery learning, higher order thinking skills, Plomp development model, colligative properties of solutions. DOI: http://dx.doi.org/10.23960/jpmipa/v23i3.pp1038-1046
