There is an emerging consensus that spatial thinking is fundamental to later success in math and science. The goals of this study were to design and evaluate a novel test of three-dimensional (3D) mental rotation for 4- to 8-year-old children (N?=?165) that uses tangible 3D objects. Results revealed that the measure was both valid and reliable and…

The relations among various spatial and mathematics skills were assessed in a cross-sectional study of 854 children from kindergarten, third, and sixth grades (i.e., 5 to 13 years of age). Children completed a battery of spatial mathematics tests and their scores were submitted to exploratory factor analyses both within and across domains. In the…

The relation of visual process to Piaget's stages of cognitive development was examined. The study utilized four age groups to correspond roughly to acquisition and consolidation periods of concrete and formal operations: 6 years - acquisition of concrete operations; 9 years - consolidation of concrete operations; 11 years - acquisition of formal…

A study designed to test the Piagetian theory that distinct stages in the organization of memory relating to horizontality correspond to successive stages in operative level was conducted with 154 twelve- to fourteen-year-old subjects. Loglinear and path analysis models were used to describe the association between operative level and spatial…

The structure of inquiry in art is a set of behavioral stages, comparable with creative process stages, in which persons think in and about the visual mode of perception. The stages include behaviors identified by Dewey as factors or phases of reflective thought and as stages in the pattern of inquiry. The stages also show relatedness to problem…
