Drawing on Experience: Use of Sketching to Evaluate Knowledge of Spatial Scientific Concepts


How does learning affect the structure of domain knowledge? This question is difficult to address in domains such as geoscience, where spatial knowledge is paramount. We explore a new platform, called CogSketch, for collecting and analyzing participants’ sketches as a means of discerning their spatial knowledge. Participants with differing levels of experience in the geosciences produced sketches of geologic structures and processes on a tablet computer running CogSketch software. This allowed for the analysis of not only the spatial-relational structure of the sketches, but also the process through which the sketches were constructed.
