Effect of Video Tutorial on Students’ Skill Performance, Interest and Retention in Basic Electronics in Technical Colleges in Rivers State

Abstract

This study was designed to determine the Effects of Video Tutorial on Students’ skills Performance, Interest and Retention in Basic Electronics in Technical Colleges in Rivers State. Three specific objectives, three research questions and three null hypotheses guided the study. The study adopted a quasi – experimental design of non-randomized pre-test, post-test controls group. The population for the study comprised of 89 students of ST3 all from the Technical Colleges in Rivers State. The sample size of the study consisted of 120 students. The instruments used for data collection were Basic Electronics Performance Test (BEPT) and Basic Electronics Interest Inventory (BEII). To ensure content validity of the BEPT, a test blue print (Table of specification) was used to build the test. The BEPT, BEII and lesson plans developed for the experimental and control groups were subjected to face validation by three experts all from University of Uyo. The BEPT was trial tested twenty (20) students who were not research sample for the purpose of determining the psychometric indices of the test. The reliability coefficient of the Basic Electronics Performance Test (BEPT) and the Basic Electronics Interest Inventory (BEII) obtained through Cronbach alpha statistics were 0.87 and 0. 89 respectively. The high reliability indices indicated that the instruments were reliable for use in the study. The data collected were analyzed using mean and standard deviation to answer the research questions, t-test was used to hypotheses 1-3. Based on the findings of the study, it could be concluded that the use of video tutorial instructional method enhances students’ skills performance, interest and retention in Basic Electronics than using demonstration method. Finally, from the study the researcher recommended that Basic Electronics teachers and instructors in all public Technical Colleges in Rivers State should henceforth adopt video tutorial in teaching topics in Basic Electronics in order to improve students’ skills performance, interest and retention in Basic Electronics.
