Abilities Measured by the Purdue Elementary Problem-Solving Inventory

Abstract
Data from the Purdue Elementary Problem-Solving Inventory for 364 second-graders were analyzed. The inventory was designed to assess 12 distinct problem-solving skills. A principal axis factor solution with varimax and then oblique rotations was computed from tetrachoric item intercorrelations. 6 psychologically interpretable factors emerged. These 6 factors corresponded to 6 of the hypothesized 12 component abilities involved in the test. Items representative of these factors appeared to assess the ability to sense that a problem exists, define the problem specifically, notice details, see implications, make remote associations, and select the best solution to a problem.
