Abstract

This study aims to develop a mathematics teaching e-module based on the Realistic Mathematics Education (RME) approach within the peatlands context for Grade VIII students on the Pythagorean Theorem. The research applies nine stages of the Dick and Carey instructional design model: identifying instructional goals, conducting instructional analysis, analyzing learners and contexts, writing performance objectives, developing assessment instruments, designing instructional strategies, developing instructional materials, conducting formative evaluation, and revising instruction. The study involved 31 students and one mathematics teacher. Data were collected through expert validation sheets and response questionnaires for teachers and students. Expert validation results showed that all aspects of the e-module and student worksheet (LKPD) including content, context, evaluation, media, language, format, and layout achieved high validity. Teachers and students rated the product in the Good to Very Good category, which means the e-module and LKPD are feasible for classroom use. Revisions based on expert and user feedback made the Final Prototype clearer and more engaging. Overall, the study indicates that the RME-based e-module with a peatland context is valid, practical, and effective in improving students’ understanding of the Pythagorean Theorem throught contextual learning.

Abstract

It is becoming more and more necessary for educational practices to use digital technologies that can facilitate efficient and meaningful learning in the age of rapid technology advancement. Digital technology is crucial in mathematics education because it helps pupils envision and comprehend abstract ideas that are frequently challenging to learn through traditional teaching methods. The purpose of this study is to examine students’ views on the use of GeoGebra Augmented Reality (AR) in mathematics classes at public junior high schools in Palangka Raya. Twenty questions covering five areas—knowledge and awareness, usefulness and application, obstacles and restrictions, support and facilities, and interest and attitude—were answered by 248 students using a survey method with a descriptive quantitative approach. The findings indicate that students’ overall perceptions of GeoGebra AR are high, especially regarding its usefulness, their interest in it, and the support from their schools. They still have to deal with issues like device availability and restricted internet access, though. In conclusion, GeoGebra AR has great potential as an innovative learning tool to boost students’ motivation and understanding of math, in line with the Merdeka Curriculum.
