AutoCAD Application on Students Performance in Technical Drawing for Sustainable Development in Nigeria

Abstract

Effect of AutoCAD Application on Students in performance in Technical Drawing for sustainable development in Nigeria. Two research objectives, two research questions were raised and two null hypotheses were formulated and tested in the study. A quasi-experimental design was used for this study. The population of the study was 1,521 first-year senior secondary school students of the nine senior secondary schools that have computer laboratories and offering Technical Drawing. Ninety senior secondary students from three selected schools in the three senatorial zones in Niger State were used as the sample. Twenty multiple-choice questions and two practical questions in the Technical Drawing Achievement Test. The reliability coefficient of the instrument was found to be 0.91 using Kudar-Richardson formula 2(K-R 21) which shows that the test items are reliable. Mean, and the standard deviation was used to answer the research questions and Analysis of Covariance (ANCOVA) was used to test the two null hypotheses. Null hypotheses were tested at 0.05 level of significance. The findings of the study revealed among others that, there was a significant difference between the pre-test and post-test results in the objective test. Similarly, the study revealed that there was a significant difference between the pre-test and post-test results of the practical test for Technical Drawing students. Based on the findings it was recommended that Technical Drawing teachers should be trained in the use of AutoCAD Application in teaching Technical Drawing through workshops, seminars, and induction courses to be organized by the Ministry of Education.
