The original Purdue Rotations test systematically increases in difficulty and our item selection provided a range of difficulty levels.
In the Purdue Rotations test (Guay, 1976), students solve a spatial analogy by viewing a diagram of a 3D object before and after rotation.
A previous training study focusing on 3D spatial skills in Grades 8 11, found similar performance improvements on a simplified version of the Purdue Rotations test that also contained only ten items (Sorby, Drummer, & Molzon, 2006).
