<![CDATA[This research is motivated by students' difficulties in understanding and solving Linear Equation System of Two Variables (SPLDV) problems. This study aims to develop a valid, practical, and effective Android-based learning media using Construct 2 on SPLDV material to support interactive mathematics learning. This research employs a Research and Development (R&D) method, utilizing a 4D model (Define, Design, Develop, and Disseminate). The research subjects were 30 eighth-grade students at MTsN Gowa. The instruments used included validation sheets, teacher and student response questionnaires, as well as pre-test and post-test. The results showed that the learning media met the very valid criteria with an average expert assessment percentage of 94.52%. The media was also declared very practical based on 100% learning implementation, 92.50% teacher response, and 89.56% student response. Furthermore, the media proved effective with a classical completeness of 76.67% and an increase in average student learning outcomes from 27.17 to 80.50. In conclusion, this Android-based learning media is feasible and effectively used as an interactive learning alternative for SPLDV material.]]>
