Assessment of the Skills Possessed By the Teachers of Metalwork in the Use of Computer Numerically Controlled Machine Tools in Technical Colleges in Oyo State

Abstract

The purpose of this study was to assess the skills possessed by the teachers of metalwork in the use of computer  numerically controlled machine tools in technical colleges in Oyo State. Three research questions and three null hypotheses tested at 0.05 level of significance guided the study. A survey research design was adopted for the study. The population for the study comprised of all the 35 metalwork teachers in the technical colleges in Oyo State. A structured questionnaire consisting of 41 items was used for data collection. Two experts from the Department of Vocational Teacher Education, University of Nigeria, Nsukka, and one expert from the Advanced Manufacturing Unit, Scientific Equipment Development Institute, Akuke, Enugu, face validated the instrument. The reliability co-efficience of the instrument was 0.86. Data collected were analyzed using mean and standard deviation for the research questions while t-test was used for testing the null hypotheses. It was found from the study that six skills were not possessed by metalwork teachers in the use of computer numerically controlled lathe and grinding machine, while seven skills were not possessed in using computer numerically controlled milling machine.  It was recommended that regular and systematic retraining should be organized for metalwork teachers who lack required skills in using these machines.
