Effect of Teaching Turning Operations with Fabricated Woodwork Mini-lathe on Student’s Achievement in Carpentry and Joinery in Technical Colleges in Rivers State

Abstract

The study examined the effect of teaching turning operations with fabricated woodwork mini-lathe on students’ achievement in carpentry and joinery in Technical Colleges in Rivers State, Nigeria. One research question and one hypothesis guided the research. The hypothesis was tested at 0.05 level of significance. The study adopted quasi-experimental research design. The population of the study was all the 50 National Technical Certificate 1 (NTC 1) students of the two (2) Technical Colleges offering Carpentry and Joinery Craft in Rivers State (Government Technical College Port Harcourt – 45 and Ahoada – 5). Census sampling technique was adopted and all 50 were sampled due to the manageable size of the population. The instrument used was an achievement test titled; Turning Operations with Fabricated Woodwork Mini-Lathe Achievement Test (TOFWMAT), it had 25 multiple choice questions to choose either A, B, C or D. The judgment rule was to accept mean rating and standard deviation of 3.50, and reject any mean response below 3.50. The null hypothesis was rejected when the calculated value, (F- cal) exceeded the critical value (F- cri), otherwise accept, the test instrument was judged reliable with reliability index of 0.71, 0.75 and 0.72, 0.76 respectively, through pilot tests conducted in Sapele. The findings of the study revealed that students get motivated and learn better with equipment, it was concluded that, turning operations is best taught with fabricated wood work mini-lathe than flip chart, and it recommended the improvisation of locally sourced equipment for teaching aid.
