ABSTRACT
This chapter focuses on the analysis of cognitive strategies for dealing with unfamiliar aspects of new tasks. The results of the analyses take the form of Systematic Approach to Problem Solving (SAPs) that specify how competent task performers organize their own behaviours. The chapter discusses the specification of SAPs, including the identification of phases in problem solving and the rules of thumb that may help to successfully complete each phase. It also focuses on the analysis of intuitive cognitive strategies because the existence of such strategies may interfere with the acquisition of more effective strategies. The chapter describes the use of SAPs in the design process because SAPs are helpful for designing problem-solving guidance, refining a sequence of task classes, and designing supportive information. For each of those activities, the existence of intuitive strategies may affect the selection of instructional methods.
