Development Of RME-Based Digital Modules On Numeracy Skills Of Phase E Students

Abstract

This study aims to develop a digital module based on Realistic Mathematics Education (RME) that can improve the numeracy skills of Phase E students at SMA Negeri 1 Slawi. The module is designed with RME principles, utilizing real-life contexts, especially in trigonometry material, making it easier for students to understand mathematical concepts. This research uses the Research and Development (R&D) method which includes three main stages: needs analysis, design, and product development. According to Sugiyono (2018: 27), R&D research enables the development of products that are valid and relevant to user needs through repeated evaluations. This research data shows that 94% of students need active learning and 96% want relevant and interesting digital teaching materials. The learning media validation obtained an average score of 94%, while the material validation obtained a score of 96%, both of which were in the very valid category (Arikunto, 2020: 86). This module is equipped with interactive features such as videos, quizzes, and context-based evaluation, which according to Trianto (2019: 48) is one of the effective strategies in supporting active and independent learning. With these results, the RME-based digital module is considered very feasible and effective in improving students' numeracy skills.
