Motivasi pembelajaran

Dengan menggunakan istilah media pengajaran, Sudjana dan Rivai (1992) mengemukakan beberapa manfaat media dalam proses belajar siswa, yaitu: 

• dapat menumbuhkan motivasi belajar siswa karena pengajaran akan lebih menarik perhatian mereka; 
• makna bahan pengajaran akan menjadi lebih jelas sehingga dapat dipahami siswa dan memungkinkan terjadinya penguasaan serta pencapaian tujuan pengajaran;
• metode mengajar akan lebih bervariasi, tidak semata-mata didasarkan atas komunikasi verbal melalui kata-kata; dan 
• siswa lebih banyak melakukan aktivitas selama kegiatan belajar, tidak hanya mendengarkan tetapi juga mengamati, mendemonstrasikan, melakukan langsung, dan memerankan.

         Penggunaan media dalam kegiatan belajar mengajar memiliki pengaruh yang besar terhadap alat-alat indera. Terhadap pemahaman isi pelajaran, secara nalar dapat dikemukakan bahwa dengan penggunaan media akan lebih menjamin terjadinya pemahaman yang lebih baik pada siswa. Pebelajar yang belajar lewat mendengarkan saja akan berbeda tingkat pemahaman dan lamanya “ingatan” bertahan, dibandingkan dengan pebelajar yang belajar lewat melihat atau sekaligus mendengarkan dan melihat. Media pembelajaran juga mampu membangkitkan dan membawa pebelajar ke dalam suasana rasa senang dan gembira, di mana ada keterlibatan emosianal dan mental. Tentu hal ini berpengaruh terhadap semangat mereka belajar dan kondisi pembelajaran yang lebih hidup, yang nantinya bermuara kepada peningkatan pemahaman pebelajar terhadap materi ajar.
