The question we should ask now is this: Which instructional strategies will prove useful in developing critical thinking
skills within this emerging discipline of visualization? Research performed by McKenzie and Padilla (1984),

in three-dimensional space once required a well-developed imagination. Fortunately, students today can augment their
mental capabilities with the use of a computer system . . . (p.3).
