EFFECT OF PROJECTED INSTRUCTIONAL MEDIA ON STUDENTS ' ACADEMIC PERFORMANCE IN PHYSICS AMONG SECONDARY SCHOOLS IN KATSINA ZONAL EDUCATION QUALITY ASSURANCE

Abstract

The study examined the effect of projected instructional media on students’ academic performance in physics among secondary schools in Katsina Zonal Education Quality Assurance. The study developed two objectives, answered two research questions and tested two research hypotheses. The study adopted Quasi-experimental research design. The population of the study comprised of 12,853 students from 25 secondary schools in Katsina Zonal Education Quality Assurance. Two schools were selected purposively, and intact classes were used in each school with a sample size of 156 students. Validated Physics Performance Test (PPT) with a reliability coefficient of 0.80 was used for data collection. The Research questions were answered using mean and standard deviation, while null hypotheses were tested at p<0.05 level of ‘significance using t-test independent sample. The findings revealed significant difference exists in the academic performance of the subjects exposed to projected instructional media and those taught using lecture method. Subject in the experimental group developed and obtained a significantly higher academic performance than subjects than in the control group. It was concluded that the students taught Physics using Projected Instructional Media perform significantly better than those taught using lecture method. It was recommended that Physics concepts should be taught using projected instructional media so as to improve students’ academic performance.
