The Effect of Computer-Assisted Instructional Package for Teaching Metalwork Technology (MWT) at Nigeria Certificate in Deucalion (Technical) Level

Abstract

This study identified the effects of using Computer-Assisted Instructional (CAl) package for teaching Metalwork Technology (MWT) at the Nigerian Certificate in Education (Technical) level. Two research questions and two research hypotheses were formulated to guide the study at 0.05 level of significance. The study used post- test only type of quasi experimental research design. Two hundred and eighty students of 200 level NCE (Technical) programme were used as respondents in the study from seven institutions in the North-central geo-political zone of Nigeria. One hundred and forty students each were assigned to the control and experimenta1 groups respectively. Both the control and the experimental groups were taught MWT using the lecture and CAI package methods respectively and administered with Metalwork Technology Achievement Test (MWTAT) in a post-test. The data from the post-test were analyzed using the mean and standard deviation to answer the two research questions and t-test statistics was used to test the two hypotheses in the study. The study found that the subjects in the experimental group performed better than their counterparts in the control group in the post-test with mean score of 23.76. The subjects in the Federal Colleges of Education and Polytechnics performed better than those in the State Colleges of Education and Polytechnics. The study also found significant differences in the performances of the control and the experimental group and between those in the Federal-owned and State- owned institutions. Some recommendations made in the study include Colleges of Educations and Polytechnics offering NCE (Technical) programme should have well equipped computer centers for teaching and learning metalwork technology. Institutions should adopt the CAl package for teaching students metalwork technology.
