Effect of Youtube Videos on Students’ Academic Achievement in Mechanical Engineering Craft Practice in Technical Colleges in Rivers State

Abstract

The aim of this study is to ascertain the effect of YouTube videos on Students’ academic achievement in Mechanical Engineering Craft Practice in technical Colleges in Rivers. Specifically, the study sought to ascertain the effect of YouTube videos on Students’ academic achievement in welding operations in technical Colleges in Rivers State. One research question and one hypothesis guided the study. The study adopted a quasi-experimental design. The population for the study consisted of 53 NTC 2 students of Mechanical Engineering Craft Practice in all the approved technical Colleges in Rivers and the entire population of 53 students were used for the study. The instrument was sent to three experts in the Department of Industrial Technical Education, Ignatius Ajuru University of Education, Port Harcourt. The experts carried out both content and face validity to ascertain the suitability of the items in the instrument. To ensure the reliability of the instruments, 15 copies of the Mechanical Engineering Craft Practice Achievement Test (MECPAT) were administered on 15 NTC 2 students in Federal Science and Technical College Ahoada. These students were not part of the population of the study. Thereafter Kuder-Richardson 20 formula was applied which yielded a reliability of 0.85 indicating that the instrument was reliable. The data gathered from the study were analyzed using mean, standard deviation, and Analysis of Covariance (ANCOVA). The mean and standard deviation were used to analyze the research questions. A mean gain indicates that the experimental group performed more than the control group, while a mean loss indicates a better performance in the Mechanical Engineering Craft Practice Achievement Test (MECPAT) in favour of the control group. The Analysis of Covariance ANCOVA was used to test the null hypotheses at .05 degree of significance. In testing the hypothesis, when the F-ratio is greater than .05 the null hypothesis is accepted, when the F-ratio is less than .05 the null hypothesis is rejected
