Utilization of AutoCAD for Teaching and Learning of Technical Drawing in Oyo and Ogun State Universities of Education

Abstract

Preliminary observations of Nigerian universities indicate that a substantial proportion of lecturers and students continue to depend on conventional lecture-based approaches, with limited integration of technologies. In response to this situation, this study examined the extent to which AutoCAD is utilized in the teaching and learning of technical drawing in Universities of Education. The investigation was guided by two research questions and two null hypotheses were formulated and tested at the 0.05 level of significance. Survey research design was employed for the study. The population consisted of 28-lecturers and 105-students from the selected Universities of Education in Oyo and Ogun States. Given the manageable size of the population, a total enumeration technique was adopted. Data were collected using a structured questionnaire designed on a four-point modified Likert scale. Content validity of the instrument was established by 3-research experts, while a pilot test was conducted to determine its reliability. Reliability coefficients of 0.93 for lecturers and 0.91 for students were obtained using the Cronbach Alpha method. Descriptive statistics, including percentages, mean and standard deviation, were used to analyze the research questions, moreso t-test was utilized for hypotheses testing at 0.05 significance level. It was revealed that the use of AutoCAD for teaching and learning technical drawing by both lecturers and students was generally low. Furthermore, no statistically significant difference was found between the mean ratings of federal and state lecturers and students regarding their utilization of AutoCAD for instructional purposes. Based on these findings, it was recommended that academic departments should regularly organize workshops and retraining programmes to enhance technology education lecturers’ competence in the use of AutoCAD. Additionally, lecturers should intensify efforts to promote active students participation through increased integration of AutoCAD in teaching process.
