Abstrak. Salah satu faktor penyebab pembelajaran matematika di SMPLB berjalan kurang maksimal adalah pengunaan bahan ajar. Bahan ajar yang digunakan oleh guru dalam pembelajaran pada anak-anak tunarungu di SMPLB di Kota Kupang masih menggunakan bahan ajar yang sama dengan siswa normal. maka perlu adanya bahan ajar yang sesuai dengan kebutuhan dan karakteristik mereka. Penelitian ini bertujuan untuk menghasilkan sebuah buku matematika khusus untuk anak-anak tunarungu, yang berbasis pada visualisasi dan realistik. Metode yang digunakan adalah metode pengembangan dengan model 4D rancangan Thaiagaradjan dimana terdiri dari empat tahap yaitu, pendefinisian (define), perancangan (design), pengembangan (develop), dan penyebaran.  Instrumen yang dikembangkan dalam penelitian ini terdiri atas enam macam, yakni (1) lembar validasi bahan ajar, (2) lembar keterbacaan bahan ajar, (3) lembar observasi aktivitas guru, (4) lembar observasi aktivitas anak-anak tunarungu, (5) angket respon anak-anak tunarungu dan (6) lembar tes tulis. Indicator penilaian dari penelitian pengembangan ini meliputi valid, praktis dan efektif. Hasil analisis menunjukkan bahan ajar yang dikembangkan memenuhi kriteria valid, praktis dan efektif, sehingga bahan ajar tersebut berkulaitas baik dan dapat digunakan dalam pembelajaran matematika bagi siswa SMPLB Kelas VII.

Kata Kunci: Tunarunggu, Bahan Ajar, Visual, Realistik, Matematika.
