THE EFFECTIVENESS OF MATHEMATICS LEARNING USING INSTRUCTIONAL MEDIA FOR EIGHTH-GRADE STUDENTS ON THREE-DIMENSIONAL SHAPES

This research was motivated by the low mathematics learning outcomes among students. The objective of this study is to enhance mathematics learning outcomes through the use of Android-based instructional media. The research design employed was classroom action research, aimed at determining the effectiveness of mathematics instruction using the Geometry Adventure learning media among eighth-grade students at SMP Muhammadiyah 22 Setiabudi Pamulang, with a sample size of 32 students. Data were collected using several research instruments, including learning outcome tests, student activity observations, student response questionnaires, and learning implementation assessments. The findings of the study indicate that the use of the Geometry Adventure learning media positively impacts student learning outcomes, enhances student engagement and participation in the learning process, and fosters positive student responses toward mathematics instruction. Furthermore, teachers found it beneficial in managing a more interactive and conducive learning environment, making the learning process more effective and enjoyable. These findings provide a foundation for the development of more innovative technology-based learning media and their application to broader educational contexts and subject matter.
