Three-dimensional spatial skills are a cognitive ability that have been shown to predict success in engineering. Michigan Tech has been offering a course to help students improve their 3-D spatial skills for more than two decades. In previous studies, students who failed a rotations test and enrolled in the course performed better on a number of…

The impact of spatial visualization ability on student outcomes in a freshman-level, 3D modeling class is explored by analyzing connections between students' spatial ability pre- and post-test scores, course grades, and self-reported difficulty of an assignment. Analysis of the results indicate that spatial visualization ability, as measured by…
