Background of the study

English language is a global prestigious system of human communication used either by spoken or written, consisting of words in a structured and conventional way. It is the official language in Nigeria, which used in education, government, administrative, law, and commerce.On this account, it is necessary to ensure that, the secondary school students are given the basic and fundamental facet of English language. In order to achieve this; there must be instructional materials like Audio visual aids which are permeating the educational system as tools for effective teaching and learning. With audio visual, the communication of information can be done in a more effective manner and it can be an effective instructional medium for delivering information. Audio visual access to knowledge is one of the possibilities of information and communication technology that has tremendous impact on learning. The instructional media have emerged in a variety of resources, and equipment, which can be used to supplement or complement the teacher’s efforts in ensuring effective learning by students. It is recognized that conventional media technologies can no longer meet the needs of our teaching and learning processes; as a result they are being replaced by audio visual technology. This technology provides a learning environment that is self-paced, learner-controlled and individualized.

Audio visual is defined as the combination of various digital media types such as text, images, sound and video, into an integrated multi-sensory interactive application or presentation to convey a message or information. In other words, audio visual means “an individual or a small group using a computer to interact with information that is represented in several media, by repeatedly selecting what to see and hear next” (Agnew, Kellerman and Meyer, 2011).

Reisman (2010) described audio visual as a ray of “computer-driven interactive communication system, which create, store, transmit and retrieve, textual, graphic and audio tory networks of information.
