DEVELOPMENT OF ANDROID-BASED EXPOMATH MEDIA WITH A DIFFERENTIATED APPROACH TO IMPROVE STUDENT LEARNING OUTCOMES AND INTERESTS
Keywords:
Expomath Media, Learning Outcomes, Student InterestAbstract
The creation of the Android-based Expomath media stems from the limited availability of learning resources that leverage technology with a differentiated approach, particularly for ranked number material. Additionally, there is a gap in the utilization of technological advancements to create learning tools tailored to diverse student needs. This study aims to enhance students' learning outcomes and interests by providing engaging, interactive media aligned with various learning styles. The research adopts the Research and Development (R&D) approach using the ADDIE model, encompassing Analysis, Planning, Development, Implementation, and Evaluation phases. The study was carried out in grade X of the Private Vocational School of the Padangsidimpuan Campus, employing both quantitative and qualitative data. Data collection methods included observations, interviews, questionnaires, tests, and documentation. The validity and practicality of the media were evaluated using a Likert scale (1-5), yielding a validity score of 92.02% and a practicality score of 92.03%, which were interpreted based on established criteria. The effectiveness test indicated an improvement in student learning outcomes, as shown by the N-Gain test results, with increases of 52.52% and 64.22%, both categorized as medium. Expomath media demonstrated a clear distinction in learning outcomes before and after its implementation. Students’ understanding of the ranked number concept improved significantly following the use of Expomath. This media has been proven valid, practical, and effective, making it a valuable tool for enhancing learning quality and benefiting students, teachers, and schools in improving educational outcomes.References
