“…In the Wagemans and Dochy study (1991 a), experiential learning was interpreted as that part of the prior knowledge that was not formally recorded but is acquired through life, work, and study. Aspects of experiential knowledge are evidenced in the work on naive conceptions (e.g., Eylon & Linn, 1988), alternative frameworks (e.g., Duit, 1987) and conceptual change (e.g., Dahlgren, 1989;Johansson, Marton, & Svensson, 1985;Marton, 1988;Roth & Anderson, 1988). Certainly, we know that all other forms of prior knowledge can be partly experiential, a factor that makes its direct representation in any conceptual map of prior knowledge impractical.…”
