In this chapter, the problem of strategy shifts in problem-solving is discussed within the framework an extended Rasch model (RM) theory. A strategy-shift model is formulated that is similar to the (generalized) solution-error response-error model of Westers & Kelderman (1991). Modeling of strategy shifts is illustrated by means of the balance-beam task of Siegler (1981), which was administered to 484 Dutch 12-to-13-year-old children. Different hypotheses regarding the strategy shifts of subjects based on Siegler’s theory concerning the balance task are specified and empirically tested.
