Improving 3D Visualization Skllls through Adaptive Learning

An introductory CAD course, a high number of students fail the course because of difficulties in understanding the 2D sketches and then visualizing components of a 3D part model created from the sketches. The course redesign will introduce new online exercises in order to improve student conceptualization and visualizations of the 3D parts, and then, the construction of the 3D model. The progressive difficulty of the exercises should gradually increase student expertise therefore improving their confidence in CAD. The proposed online exercise program will improve the teaching the principles, as well as, improve the work done in the laboratory sister course, MECH 100L.
