EFFECT OF COMPUTER AIDED DESIGN ON STUDENTS’ ACADEMIC ACHIEVEMENT IN AUTOMOBILE ELECTRICITY TECHNOLOGY IN TECHNICAL COLLEGES IN EDO STATE

Abstract

This paper investigated the effect of computer aided design on students’ academic achievement of automobile electricity technology in edo state technical colleges.The population of the study consisted of 86 students of automobile electricity technology in Technical Colleges in Edo State. Quasi pre-test, post-test group design was used for the study. Automobile electricity technology Achievement Test (AETAT) containing a total of 50 multiple choice questions formed the instrument of the study. Means and standard deviations were used to answer the research questions while t-test was used to test the null hypothesis at 0.05 level of significance. The result of the data analysis showed that there was a significant difference between the mean achievement scores of students taught AET using conventional method( X = 40.58) and those taught using CAD method ( X = 60.42). Pretest and Post-test Mean Academic Achievement Scores of Male (X = 83.92 )  and Female ( X=17.05). AET Students Taught automobile electricity operation and layout Using CAD. The results showed that there is a difference between the mean achievement scores of male and female students when exposed to experimental condition in favour of the male students in technical colleges in Edo state.The analysis also returned (t= 7.75) to reject the hull hypothesis at 0.05 level of significance. The study recommended among others that the use of CAD method of teaching should be adopted by technical teachers to improve the academic performance of Automobile electricity technology students in Edo State.
