Effect of computer numerical control machines on students’ achievement in mechanical engineering programme in state and federal polytechnics in adamawa, taraba and gombe state nigeria

The study will investigate to find out the effect of Computer Numerical Control machine on student achievement in Mechanical Engineering programmed in all state and federal Polytechnics in Adamawa, Taraba and Gombe State, four research questions in line with the purpose of the study will be formulated for the study. Four hypotheses will be formulated and tested at 0.05 level of significance study will be made. The study will be conducted using quasi–experimental design. Specifically, the pre - test post – test non-equivalent control group design. This implies that intact classes (non-randomized groups) will be use in the study. The study will be carried out in Adamawa, Taraba, and Gombe State which are located in the North-East Region of Nigeria. The target population of this study consisted of 40 diploma II students enrolled in 2018/2019 academic session in the Department of Mechanical Technology, in all state and federal Polytechnics in Adamawa, Taraba and Gombe State. The instrument for data collection will be tagged Machine Tool Achievement Test (MTAT) developed by the researcher. The instrument will be a multiple-choice question containing 40 items. Each item will have options A - D from which the respondents will choose the correct option. Questions willbe drawn from past school examination question papers of 2014 - 2019 session to form Machine Tool Achievement Test (MTAT). The statistical tools that will be used for analysis is ANCOVA. The independent variable will be the use of CNC machine and analog lathe machine. The dependent variable will be the students’ achievement scores obtained after the treatment (post-test). The pre-test performance scores will be obtained prior to the commencement of the treatment and will be use as covariate to control the group differences. Analysis of Covariance will be conducted to determine whether there is a significant difference between the students taught using CNC machine and those taught using analog lathe machine.
