EFFECTS OF IMPROVISED INSTRUCTIONAL MATERIAL ON PERFORMANCE AND RETENTION OF PROPERTIES OF WAVES AMONG SENIOR SECONDARY SCHOOL PHYSICS STUDENTS IN SULEJA METROPOLIS

Abstract

ABSTRACT The study investigated the effect of the use of improvised instructional materials, on performance and retention of properties of waves among senior secondary school physics students. Pretest, post- test experimental group design was used for the research study. The study comprised of senior secondary schools in Suleja Local Government area of Niger state. Samples of One hundred and twenty (120) students were selected through systematic sampling technique. The instrument used for collecting data was adopted from the National Examination Council (NECO) past theory question papers from 1988-2010. Having been internally validated, the items were subjected to another validation by team of experts, for content and criterion related validity. Test Re-test method with an interval of two weeks was used to obtain data for reliability co-efficient, R=0.74 was obtained. Four (4) null hypotheses were formulated, three were not rejected and one was rejected. The 12.0 Version of Statistical Package for Social Sciences (SPSS) was used to analyze the data obtained. The findings of the research work revealed that, the use of improvised instructional materials influences student’s active interest and involvement in the learning process and enhances learning and retention abilities. It was also discovered that improvisation is gender friendly. It was recommended that the government should organize seminars, workshops symposium and training on the use of improvised instrumental materials to enhance learning achievement and retention among students.
