Effect of using improvised instructional materials to enhance academic achievement of form three biology students in the teaching of respiratory system at Tepa Senior High School

Abstract

The purpose of the study was to find out the effect of using improvisation instructional materials to enhance academic achievement of form three Biology students in respiratory system at Tepa Senior High School. Research approach adopted for the study was quasi-experiment design. The instrument used to collect data for the study were questionnaire, document analysis, pre and post treatment test. The target population consisted of 300 students and 15 teachers, and the accessible population included 120 students and 10 teachers, the sampling technique used was simple random sampling. Study findings, though, the school has a biology laboratory, the school have inadequate standard practical materials for practical lessons, lack of skills for improvisation among most teachers of Tepa Senior High School, inadequate biology laboratories, used of laboratories for classroom because of large school population and inadequate classrooms, when the improvised materials was used in place of standard one due to inadequacy, the students’ achievement was excellent as experimental group scored the above average mark of 23.3% as against 3.3% in control group showing an improvement in their academic achievement when the treatment was used for experimental group . Summary and recommendations of findings, based on the research findings, the study recommends the following: Teachers of Tepa Senior High should be trained on how to at least construct basic improvisation materials, enough equipment and facilities should be secured for Tepa Senior High to ensure individualised practical activities, Management of Tepa Senior High School should ensure that teachers teach with improvised materials in absence of standard ones to enhance students understanding especially in respiratory system.
