Secara umum model pembelajaran matematika diIndonesia belum menekankan kemampuan literasi matematika. Pada penelitian sebelumnya dinyatakan guru belum bisa memanfaatkan media dalam proses pembelajaran, guru hanya berpedoman pada buku teks terbatas, kurang mendukung siswa dalam bekerja kelompok sehingga siswa cenderung bekerja individual, guru belum bisa menemukan model pembelajaran yang sesuai dengan kondisi siswa. Akibatnya nilai yang didapat belum maksimal. Namun saat ini pembelajaran terasa sangat berat dikarenakan siswa dituntut untuk belajar secara mandiri dirumah, proses pembelajaran cenderung tektbook dan kurang terkait dengan kehidupan sehari-hari, akibatnya siswa kurang menghayati atau memahami konsep-konsep matematika, dan siswa mengalami kesulitan untuk mengaplikasikan matematika dalam kehidupan sehari-hari.
Materi dimensi tiga merupakan pengembangan dari materi bangun ruang sisi datar. Pada materi dimensi tiga siswa dituntut untuk memahami konsep materi persamaan dan fungsi kuadrat, materi logika, dan materi trigonometri. Dengan dihubungkan dengan media audio visual (vidio) pembelajaran dapat lebih menarik dan menambah kemampuan siswa untuk lebih memahami materi dimensi tiga.
Berdasarkan permasalahan tersebut penulis melakukan penelitian tentang “Penerapan Model Pembelajaran Discovery  Melalui Media Audio Visual (Vidio) Berbasis Literasi pada Materi pokok Dimensi Tiga Untuk Meningkatkan Kemampuan belajar Matematika siswa kelas 12 di SMAN 4 Pasuruan"
