Penelitian ini menggunakan metode Research and Development (R&D) dengan model pengembangan ADDIE (Analisis, Perancangan, Pengembangan, Implementasi, dan Evaluasi). Hasil validasi ahli materi memperoleh skor 82% (sangat valid) dan ahli media 90% (sangat valid). Uji coba memperoleh kepraktisan dari guru 81,82% dan siswa 92,77% (sangat praktis). Keefektifan media berdasarkan peningkatan nilai dari pre-test ke post-test menunjukkan nilai N-Gain sebesar 0,67 (kategori sedang). Dengan demikian, media Wordwall dinyatakan valid, praktis, dan efektif digunakan dalam pembelajaran matematika. ABSTRACT This study aims to develop interactive Wordwall-based learning media for ninth-grade students of MTs Islamic Centre Medan on exponents and radicals, and to determine its validity, practicality, and effectiveness. This study employed a Research and Development (R&D) method with the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) development model. Validation results from material experts yielded a score of 82% (very valid) and from media experts a score of 90% (very valid). The trial yielded practicality ratings from teachers at 81.82% and students at 92.77% (very practical). The effectiveness of the media, based on the increase in scores from pre-test to post-test, showed an N-Gain of 0.67 (moderate category).
