The influence of instructional materials in promoting students’ academic performance and teaching and learning in educational development is indisputable. The teaching of English language in Nigerian secondary schools needs to be properly handled. The materials used by teachers to teach and drive home their subject points at the primary and secondary school levels of our education system is incontrovertibly a paramount issue in practical classroom interaction and successful transfer of knowledge from the teacher to the learners. Instructional materials are materials which assist teachers to make their lessons explicit to learners. They are also used to transmit information, ideas and notes to learners (Ijaduola 1997). Instructional materials include both visuals and audiovisuals such as pictures, flashcards, posters, charts, tape recorder, radio, video, television, computers among others. These materials serve as supplement to the normal processes of instruction.
English Language is an important and fundamental subject that must be credited by students before gaining admission into any tertiary institution. The importance and technicality of this subject makes it necessary that relevant instructional materials should be used to teach it to the learners.
