Effects of CAD Technology on Building Technology Students’ Interests in Building Drawing

Abstract

This study examined the effects of CAD packages on improving Building Technology students' interest in Building Drawing. Three research questions and three hypotheses guided the study. A factorial design with students in their intact classes was employed, involving 152 NCE III Building students from all Federal and State Colleges of Education in Southwest Nigeria. The sample consisted of 28 male and 11 female students. The Building Drawing Interest Inventory (BDII), developed by the researcher, was utilized. Pre-tests and post-tests of the instrument were conducted, and an Analysis of Covariance (ANCOVA) was employed to test the hypotheses. The results revealed that there was no significant difference between the effects of Autodesk Revit and AutoCAD on students’ interest in Building Drawing. Additionally, there was no significant difference between the effects of gender on students’ interest in Building Drawing, nor was there a significant interaction effect of treatment and gender on the students' interests. It was recommended that the curriculum for Building Drawing in Colleges of Education be revised to incorporate appropriate CAD technology as a training tool for Building Drawing.
