ABSTRACT

The subject of Physics which is taught at the Senior Secondary School levels in Nigeria requires demonstration and praticalisation of some concepts. A concept of power supply in physics requires the use of transformer. The transformer is used as an instructional material to see if it affected achievement in Physics. Three research questions and three null hypotheses guided the study. One hundred students were sampled for the study.  A quasi- experiment design was used and Physics Achievement test administered to collect data for the study. Analysis of result using independent t-test and chi-square indicated that students taught power with transformer as instructional materials performed significantly better than the counterparts. Findings imply that science is not really brought home if the instructional aids are not used and proper orientation should be given to teachers through seminars and workshops to promote learning and teaching.
