摘要

The purpose of this paper is to summarize the reliability and validity of scores for several mathematical and spatial-reasoning constructs that are keys to academic success in engineering. In this study, we examine the scores for two mathematical constructs and two spatial-reasoning constructs. The mathematical constructs represent students' abilities to: M1 compare and contrast mathematical operations (e.g., differentiation, integration, interpolation); and M2 represent engineering- and physics-based principles mathematically. The two spatial reasoning constructs focus on students' skills at: S1 rotating and transforming geometric objects in three-dimensional space; and S2 translating two-dimensional images to three-dimensional images and vice versa when representing visually physics-based principles such as acceleration, equilibrium, and force.
