Effect Of You-tube Videos-aided Instruction On Students’ Conceptual Understanding Of Selected Secondary School Physics Content In Ikom Education Zone Of Cross River State, Nigeria

ABSTRACT:

The study was carried out to find the Effect of You-tube Videos-Aided Instruction on Students’ Conceptu+al Understanding of Selected Secondary School Physics Contents. Two (2) research question, two (2) hypotheses were raised, answered and tested at 0.5 level of significance. Quasi-experimental design was employed by using pre-test post-test control group. Population is 1,945 SS2 Physics students in 109 public Secondary Schools in Ikom Education Zone of Cross River State. A sample size of 280 Students from 10 schools using multistage sampling technique and intact classed was used. The instrument, Physics Conceptual Understanding Test (PCUT), was validated by science education experts. A reliability coefficient of r=0.96 was calculated using Kuder Richardson formula 20(KR-20). Mean and standard deviation were used to answer the research questions while analysis of covariance test statistics (ANCOVA) was used to test the hypotheses. The result revealed that, Youtube videos-aided instruction has a far more positive effect on students’ conceptual understanding of selected physics content than lecture method. It was recommended among others that, policy makers and curriculum planners in the Ministry of Education should, as a matter of urgency, include in Physics curriculum content You-tube (version 2.0) videos as one of the instructional material for teaching Physics. Thereafter, monitoring on absolute compliance should follow, as this will lead to an improvement in students’ conceptual understanding.

Key words: YouTube Instruction, Conceptual Understanding, Physics Education, Quasi-Experimental Design, ANCOVA Analysis.
