The Correlation between Visual-Haptic Perceptual Style and Student Ability To Solve Orthographic Projection Problems in a Beginning College Drafting Course Incorporating Computer Aided Drafting.
Baird, David A.
A study determined the effectiveness of computer-aided drafting (CAD) and standard drafting instruction on the ability of students with differing visual-haptic perceptual styles to solve orthographic projection problems. A 2x2x2 factorial design was chosen to compare two levels of perceptual style with two levels of treatment and two levels of prior drafting experience. Activities were administration of the Successive Perception I test to determine visual-haptic style; administration of a questionnaire regarding prior drafting experience; provision of CAD instruction to the experimental group and traditional instruction to the control group; administration of the direct measure of orthographic projection ability; and collection of plate grades. The sample consisted of 188 beginning drafting students at the University of Missouri-Columbia. Three-way univariate analyses of covariance were used to test the hypotheses. The lack of significant differences between student scores on plate grades or the unit exam grades indicated that either instructional method could be used with equal success, visual and nonvisual students benefited equally from drafting instruction, and prior drafting experience did not ensure better skills in solving orthographic projection problems. Findings implied that visual-haptic perceptual style may not affect ability to solve orthographic projection problems. (15 references) (YLB)
