1.1 Background of the Study
The relevance of the utilization of instructional materials in the teaching and learning situation in schools cannot be over emphasized. The falling standard of education is attributed largely to the problem of unqualified teachers and lack of adequate instructional materials. Nular (1997) asserted that, when students’ interest were aroused, lesson becomes real, students, therefore, participate more actively and retain more, particularly when instructional materials are adequately used.
Instructional materials are print and non-print items that are designed to impact information to students in the educational process. Instructional materials include items, such as kits, textbooks, magazines, newspapers, pictures, recordings, slides, transparencies, videos, video Disc, work book, chat and electronic media including but not limited to music movies, radio, software, CD –ROMS and online services.
Instructional materials plays a very important roles in the teaching learning process. It enhances the memory level of the students. At this time, education has spread wide and entirely oral teaching cannot be the key to successful pedagogy, therefore, the teacher has to use instructional materials to make the teaching-learning process interesting. It is the use of instructional materials that can enhance the learning achievement (Nicholls, 2000; Raw 2003). Crobac (1989) stated the important elements of behaviour that provide the basis for learning theory: situations, the situation consists of all the objects, persons and symbols in learning environment. Experience in situation prepared a person to respond to similar situation on the future situation must be created in which learner can be satisfied. Personal characteristics under this heading will include all the abilities and all the typical responses that the person brings to the situation.
