Publisher : Universitas Negeri Surabaya

Penelitian ini bertujuan untuk mengetahui kelayakan Multimedia Interaktif (MMI) yang dikembangkan dapat digunakan sebagai media pembelajaran untuk siswa tunarungu SMALB khususnya pada materi unsur. Metode penelitian menggunakan Research and Development (R&D) dibatasi pada tahap uji coba terbatas. Instrumen yang digunakan pada penelitian adalah lembar telaah, validasi, angket respon siswa dan aktivitas writing to learn (WTL). Metode pengumpulan data terdiri atas angket dan observasi yang selanjutnya akan dianalisis secara deskriptif. MMI dikatakan layak apabila mendapat persentase ≥61% dengan kriteria baik atau sangat baik. Hasil penelitian secara teoritis maupun empiris menunjukkan MMI yang dikembangkan layak digunakan sebagai media pembelajaran. Secara teoritis kelayakan didasarkan pada hasil validasi MMI yang terdiri atas kriteria isi yang memperoleh persentase degan 75,00% - 91,67%, kriteria penyajian memperoleh persentase dengan rentang 75,00% - 91,67%, dan kriteria kebahasaan yang mendapat persentase dengan rentang 83,33% - 91,67%. Berdasarkan hasil validasi, secara teoritis MMI yang dikembangkan layak digunakan sebagai media belajar dengan kriteria baik dan sangat baik. Kelayakan MMI secara empiris yang didasarkan pada hasil angket respon siswa dengan rentang persentase 66,67% - 100% masuk dalam kriteria baik dan sangat baik, aktivitas WTL yang mendapat nilai dengan rentang 77,78% – 92,59% dinyatakan layak dengan kriteria baik dan sangat baik. Kata kunci: Tunarungu, MMI, writing to learn. Abstract This research aimed to know feasibility of develop Interactive Multimedia (MMI) to use as learning media for hearing-impaired students at SMALB especially for element material. Method used in this research was Research and Development (R&D) limited to the trial stage.
