Abstract

Mathematics is a fundamental discipline that plays an essential role in developing logical, analytical, and critical thinking skills. However, many students still face difficulties in understanding abstract concepts such as the Pythagorean theorem, which negatively impacts their learning motivation and outcomes. The purpose of this study was to design and develop interactive learning media based on Google Classroom for teaching the Pythagorean theorem to eighth-grade students. This study employed a Research and Development (R&D) approach using the ADDIE model, which consists of five stages: analysis, design, development, implementation, and evaluation. Six validators were involved, including three media experts, two material experts, and one mathematics teacher. In addition, small- and large-scale trials were conducted with 10 and 20 students, respectively. Research instruments included expert validation sheets, student and teacher questionnaires, and readability tests. Data were analyzed using descriptive quantitative techniques with percentage calculations to determine the validity and practicality of the developed product. The results showed that the interactive media obtained an average score of 86% from material experts (very valid), 78% from media experts (valid), and 84% from student responses (practical). Students reported that the media was easy to use, attractive, and helpful in understanding the Pythagorean theorem, while the teacher assessed it as very practical for classroom use. In conclusion, the developed interactive learning media based on Google Classroom is categorized as valid and practical, making it a promising alternative resource for teaching mathematics in junior high schools.
