Abstract
The need to improve academic performance of technical college students in mechanical trades necessitated this study. Thus the study proceeded to determine the effect of teaching mechanical trades concepts with multimedia on students’ academic achievement in technical colleges. One research question guided the study and one null hypothesis was tested at 0.05 alpha level. The study employed a pretest, posttest, quasi-experimental design involving two non-equivalent intact groups, (experimental group and the control group). The population was 123 National Technical College II (NTC II) students offering mechanical trades in Ondo State Nigeria. A sample of 84 students participated in the study. Purposive sampling technique was used to select two intact classes in Government technical colleges from two different local government areas of the State. Three data collection instruments, namely, the lesson plan for the experimental group, the lesson plan for the control group and the Mechanical Trade Achievement Test (MTAT) were used for the study. These were validated by three experts (one from Measurement and Evaluation unit and two from Technology and Vocational Education) all from Nnamdi Azikiwe University, Awka. The MTAT was subjected to a reliability test using Kuder Richardson 21 (KR-21) formula to yield the reliability coefficient of 0.82. Mean as well as Analysis of Covariance (ANCOVA) were used to analyze at 0.05 level of significance the data collected for the study. Findings of the study revealed that teaching with multimedia was more effective in enhancing student’s achievement in mechanical trade. Based on the findings, it was concluded that multimedia technology is more effective in improving student’s achievement in mechanical trade. Consequently it was recommended that technical college mechanical trade teachers should adopt teaching with multimedia.
Highlights
Multimedia technology is being increasingly integrated into teaching and learning process for the purpose of meeting the teaching and learning challenges facing the educational system
The following research question guided the study: What is the effect on the mean achievement scores of mechanical trade students taught with multimedia and those taught with the conventional method?
There is no significant difference between the mean achievement scores of mechanical trade students taught with multimedia and those taught with the conventional method
Summary
Multimedia technology is being increasingly integrated into teaching and learning process for the purpose of meeting the teaching and learning challenges facing the educational system. Many researchers (for example, Junaidu (2008), who have worked on multimedia have seen multimedia as those ICT based learning technologies that encompass different contents as texts, audio, images, animations, motion video, sounds, graphic images among others. It is often applied as an instructional strategy. The authors went on further to state that multimedia technology goes beyond barriers of time, location and culture and has created many better opportunities for learning outside the classroom using online materials. The students learn the materials at their own time and interact with the teacher via video-conferencing as it was found http://journal.julypress.com/index.php/jed
