Spatial Thinking & Geoscience
Spatial Thinking is “the process of problem solving via the coordinated use of space, representation, and reasoning” (NRC, 2006)

Spatial Thinking vs Spatial Ability
(Lohman, 1993; McGrew, 2009)
Uttal et al., 2012; Hegarty & Waller, 2005
Ability •An aspect of “g”•Domain-general•Apprehending, encoding, and mentally manipulating three-dimensional forms
Thinking / Skills•Domain-specific•Problem – solving with space, representation, and reasoning
