Abstract :

This R&D aims to produce a valid, practical, and effective Realistic Mathematic Education (RME)-based e-module assisted by Geosway in phase F. This research is a research and development using a 4D model consisting of 4 stages, namely defining, designing, developing, and disseminating. Observations were conducted at SMK Negeri 6 Jember as the research location. The research subjects involved in this study were students of SMK Negeri 6 Jember in grades XI DKV 1 and XI KKBT 1. The research instruments used in data collection were observation sheets, student response questionnaire sheets, readability test sheets, and test sheets. The validation results for the teaching module, e-module, test, observation sheet, and student response questionnaire were 3.73; 3.68; 3.57; 3.63; and 3.81, respectively. This shows that the teaching modules, e-modules, tests, observation sheets, and student response questionnaires were obtained with valid criteria. The practicality of the e-module based on the observation of the implementation of the e-module in the first and second meetings was 3.39 and 3.67, respectively, with the practical category. The effectiveness of the e-module was based on learning completeness, the N-gain category, and student responses to improve students’ creative thinking skills. The results of the study showed that the percentage of student completeness reached 87.5%, the average N-gain category was 0.72, and students gave a positive response of 82.07%. This indicates that the e-module is effective in improving students’ creative thinking skills. Based on the results of the study, it shows that the e-module based on Realistic Mathematic Education (RME) assisted by Geosway in phase F has valid, practical, and effective criteria.
