Effect of Video-Taped Instruction on Senior Secondary Students' Performance in Physics Practical in Port-Harcourt Metropolis, Nigeria
Science Journal of Education
This study investigated the effect of video-taped instruction on Senior Secondary Students' performance in practical physics. The design for the study is quasi-experimental, of the type, pretest-posttest control group design. The population of the study comprised of all SS3 physics students in Port Harcourt Local Government Area of Rivers State. One hundred and three (103) students in 2 co-educational schools made up the sample size. Two groups namely, the experimental group and control group
... and control group were used for the study. The experimental group was taught practical physics using video-taped instruction (VTI) while the control group was taught practical physics using the conventional (real handling of apparatus) teaching method (CM). A research question and one hypothesis were formulated to guide the study. The instrument used for the study was Physics Practical Skills Rating Scale (PPSRS). The data generated were analyzed using mean and standard deviation to answer the research question, while t-test was used to test the hypothesis at 0.05 level of significance. The calculated t-value (2.48) was significant at 0.05 level of significance. The null hypothesis H o was rejected as a result of significant difference between the performance of students taught practical physics using Video-Taped Instruction (VTI) and those taught using conventional method (CM), indicating that students taught with videotaped instruction performed better than those taught with the conventional method.
