Effect of Multi-Media Instructional Strategies on Academic Performance of Students in Radio and Television Electronic Work Trade in Technical Colleges in Kano State (Published)
This study investigated the Effect of Multi-Media Instructional Strategy on Academic Performance of Students in Radio, Television and Electronic Work Trade in Technical Colleges of Kano State. Quasi-experimental design was adopted. A sample size of 40 Technical College (NTC III) students participated in the study. Purposeful sampling technique was used to select two intact classes from two colleges. A validated 40 – items instrument from NABTEB standardized test was used to collect data on the students’ performance in the following topics; Radio Communication, Satellite Transmission / Reception and Television. To avoid bias, the researchers prepared lesson plans that were used for the teaching of the two groups. The teachers from the two technical colleges were trained on how to use the lesson plans and multi-media instructional strategy, so as to control variability in the instructional procedure in the study. Four research questions and one hypothesis were raised. The data was analyzed using SPSS, mean and standard deviation were used to answer the research questions while t-test was used to test the null hypothesis. Multi-Media instructional strategy improved the mean performance of the students in Radio, Television and Electronic Work Trade, as seen in the post-test mean performance of 46.75 as compared with pre-test mean performance of 25.75 respectively, for the experimental group. There is significant mean difference in the post-test academic performance of students taught Radio Communication, Satellite Transmission / Reception and Television using Multi-Media instructional strategy. Among the recommendations made was: Stakeholders in education should make available and encourage the use of multimedia instruction in technical colleges of Kano State by providing multimedia instructional tools.
