INTRODUCTION
Background of the Study
It is generally accepted in the world that pupil’s performance is directly influenced by the instructional materials applied. These instructional materials are the key ingredients in learning. Barnett (1992) comments that teachers should cover the materials in the curriculum and prepares pupils for standardized tests. This may have happened in western countries because of adequate resources. Nevertheless these instructional materials have not been used in the right way in sub-Saharan region particularly in Kenya. Teachers have neglected the use of these materials and in a way they have watered down pupil’s motivation as far as learning is concerned. All these bring to poor performance of the pupils especially in Westland zone in Nairobi County.
Statement of the Problem
Many students are performing poorly year after year in their examinations in Westland zone and this situation is growing worse. This in turn opens their door to poor life thereafter. This poor performance may be brought by non-innovative teachers who may not want to use the instructional materials in the right way. Unqualified teachers may also bring this problem. In this case it calls for a research to be carried out in this zone to find out exactly what the problem is.
