This contribution presents two major findings from a qualitative investigation into spatial ability. The elicited data suggested that one of the significant differences between individuals identified as high and low in spatial ability was their decomposition skill relative to spatial problems. Also revealing was the impact of frustration and…

A Delphi panel of 15 experts determined that (1) computer-assisted drafting (CAD) and traditional drafting are complementary; (2) differences in teaching strategies related to use of computers versus traditional drafting instruments; and (3) traditional drafting knowledge and skills are very important for CAD.

A treatment group of technical-graphics students who were taught drafting principles using an interactive multimedia device to enhance instructor presentation of the material scored significantly higher, retained more, and had better attitudes than controls. There were no differences in amount of instructional time, but considerably more…

A control group of 17 engineering students produced 2- and 3-dimensional shapes with manual drafting tools; an experimental group of 12 used computer-assisted drafting. From pre/posttest data, it appeared that computer models were no better at improving spatial visualization or orthographic projection skills. (SK)

Two approaches are compared in the Kentucky study: (1) the in-school, traditional, approach and (2) the cooperative work experience approach. Pretest and post-test scores were evaluated, indicating that both approaches were equally effective. (MW)

According to Farrell and Kotrlik (2003), educators can become more effective teachers by assessing their students' preferred learning styles. This assessment can help in planning the curriculum and in selecting appropriate instructional methods. Thus, research is needed to determine if there is a link between students' learning styles and their…
