Abstract

The numerical ability in Indonesia is still low and has an influence on students' academic achievement, including student's problemsolving ability. The purpose of this research was to produce STEM-based digital learning media which can develop students' numeracy and self-regulated learning in the subject of Two-Variable Linear Equation System (SPLDV) for VIII grade and its validation, practicality and effectiveness. The research adopted Research and Development (R&D) model through ADDIE with five main processes including arrays: analyze, design, develop, implement and evaluate. Subjects The subjects of this research were 22 eighth graders at a MTsN in Sleman Regency in the odd semester of academic year 2024/2025. Data were collected using a questionnaire and numeracy test, then analyzed by paired sample t-test and N-gain formula. Results indicated that learning media which was a form of smartphone application was appropriate, feasible and effective with the average numeracy score increase from 36.91 to 79.27 and for self-regulated learning test was from 44.95 to 74.09. The integration of the STEM approach with the self-regulated learning strategy was proven to improve students' numeracy and self-regulated learning. Future study is required to develop the interactive learning media can improve its content and interface and has effectiveness on a wider sample and school level.
