Effects of Multimedia Instruction on Student’s Academic Achievement and Retention in Auto Mechanics at Technical Colleges

Abstract

The study investigated the effects of multimedia instruction on student’s achievements and retention in auto-mechanics at technical colleges in Niger state, Nigeria using quasi experimental pretest posttest non-equivalent research design. The population for the study consisted of 94 NTC II technical auto-mechanics students. Two research questions were raised and answered as well as two hypotheses were formulated and tested at 0.05 level of significance. The instruments used for data collection were Auto Mechanics Achievement Test (AMAT). The reliability Coefficient of AMAT was found to be 0.83 using Pearson Product Moment Correlation coefficient. Mean was used to answer the research questions while t- test was employed to test the hypotheses. Findings from the study revealed that multimedia instruction is more effective in improving student’s achievement and retention in auto-mechanics than conventional method. There was significant difference in the student’s achievement and retention mean scores in favouring students in the experimental group. It was therefore recommended that teachers in technical colleges should adopt multimedia instruction in teaching auto-mechanics.
