In this paper we will discuss ways to incorporate basic drafting principles in our introductory class and strengthen the students’ learning experience through multiple courses in our engineering technology programs. Students will gain the basic knowledge of CAD in EGT 212 (Computer-Aided Drafting and Design), and strengthen their learning experiences by applying their knowledge in other courses such as: EGT116 (Introduction to Manufacturing), 265 (Manufacturing Processes and Metrology), 365 (CNC & Manufacturing Process Planning), 405 (Metrology and Geometric Tolerancing), 465 (Automated Manufacturing Systems) and 380 (Machine Design). They will learn the advanced features of CAD in our advanced CAD design classes. There is no doubt in obvious benefits of computer generated graphics and these changes will be made under the basic assumptions of constructivism teaching philosophy, including their implications for courses in engineering/technology design. A brief overview of the constructivist learning approach in CAD education is also discussed.
