Effects of Computer Assisted Instructional Technique on Students’ Achievement in Motor Vehicle Mechanic Trade at Technical Colle

Abstract

This study investigated the effects of computer assisted instructional technique on students’ achievement in motor vehicle mechanic trade at technical college level in Niger State. Three research questions and three null hypotheses guided the study. Quai-experimental research design was employed for the study. The study was carried out in all the seven (7) technical colleges in Niger State. The targeted population for the study was 193 TC II motor vehicle mechanic students in all the technical colleges in Niger State. The entire population was used for the study. A total of 110 students (95male 15 female) was used for experimental group A (CAI) and 83 students (67 male 16 female) was used for experimental group B (Control group). A 40-item multiple choice Motor Vehicle Mechanic Achievement Test (MVMAT) developed by the researcher was used for the data collected for the study. The instrument was validated by three experts. Two Lecturers from Industrial and Technology Education Department, Federal University of Technology, Minna and one Motor Vehicle Mechanic Teacher from Government Technical College, Eyagi-Bida. The reliability coefficient of the instrument (MVMAT) was 0.89 through Kuder Richardson 21(K-R21) statistics. Mean and Standard Deviation were the statistical instrument used for answering research questions; while ANCOVA was employed to test the null hypotheses formulated for the study at .05 level of significance. The findings among others revealed that that students taught motor vehicle mechanic students with computer assisted instruction had significantly higher mean achievement score than the students taught with conventional lecture method. The finding further revealed that the use of CAI appreciably increased the performance of both male and female students than the use of conventional lecture method. In addition, the findings further that gender of the students had no significant (p<0.05) interaction effects with the treatment given to them. Based on findings, it was recommended that motor vehicle mechanic teachers should adopt the use of this technique for instructional delivery in technical colleges so as to improves the academic achievement of TCII motor vehicle mechanic students at technical college level in Niger State and seminars, workshops and conferences should be organized by the State Science and Technical School’s Board where technical teachers and curriculum planners will be taught the application and usage of various modern teaching techniques such computer assisted instruction (CAI) for effective teaching and learning of motor vehicle mechanic trade and other technical vocational courses in technical colleges.
