Prosedur pengembangan mengikuti 4 prosedur model 4-D yang dikembangkan oleh Thiagarajan, dkk (1974) antara lain; Define (Pendefinisian), Design (Perancangan), Develop (Pengembangan) dan Disseminate (Penyebaran). Instrumen dalam pengembangan ini menggunakan angket respon siswa, lembar observasi aktivitas guru, lembar observasi aktivitas siswa dan lembar tes. Teknik analisis data yang digunakan adalah analisis uji kelayakan, analisis uji kemenarikan dan uji keefektifan. Hasil uji kelayakan diperoleh dari ahli materi, ahli desain pembelajaran, ahli media dan ahli bahasa sebesar 88,13%. Tingkat keefektifan dalam uji kelompok besar dari observasi aktivitas guru 93,75%, observasi aktivitas siswa 92,7%, dan hasil tes 87,5%, sedangkan tingkat kemenarikan produk dari respon siswa mencapai 96%.
