The necessity of various techniques for teaching English as a Foreign Language (EFL) leads teachers to use technological tools to facilitate learning and serve their learners. Audio-visual materials are widely used for academic purposes and have a vital role in education. Audio-visual aids in teaching and learning can arouse students' interest in learning new concepts. It is universally acknowledged that the use of audio-visual aids contributes to students' learning. Thousands of years ago, audio-visual materials were the primary source of learning for people at large. The primitive human-beings expressed themselves and depicted their desires by drawing on the walls of caves. As life developed, primitive human beings began to learn from their surroundings and imitation and trial were their tools and means for learning. As text and print were developed, we almost began to lose our skills with audio-visual materials. The researches on "how people learn" shed light on the importance of the employment of audio-visual aids in teaching and learning. It is observed that whenever teachers use learning aids, students feel motivated, become more attentive, exhibit interest, and quickly understand things. The use of various tools helps students learn the language efficiently and effectively. Moreover, the use of audio-visual aids in teaching English is essential because it can stimulate students' participation in classroom activities, and thus in the teaching process.
