Basic IdeasInteraction not just encodingConstruction not just recall
Cognitive ScienceDewey (1896): “Sequences of acts are composed such that
subsequent experiences categorize and hence give meaning to what was experienced before.”
Gero (1998): “where you are when you do what you do matters”
Experimental StudiesSchön and Wiggins (1992): “interaction of making and seeing”
Suwa, Gero and Purcell (1999): “Sketches serve as a physical setting in which design thoughts are constructed on the fly in a situated way.”
