This chapter discusses the specification of prerequisite knowledge, including the identification of concepts, plans, and principles as well as their further analysis into facts and, if applicable, physical models. It discusses the empirical analysis of misconceptions because they may interfere with the acquisition of prerequisite knowledge. The chapter describes the use of prerequisite knowledge for the design process. Conceptual knowledge is described in terms of domain models, which offer rich descriptions of how the world is organized in a particular domain; these models use concepts, plans, and principles as their building blocks. Plans and principles may be analyzed into their constituting concepts. Concepts, in turn, may be further analyzed into facts and/or physical models that apply to instances of the concept. Identification of misconceptions and misunderstandings may affect design decisions. Identification of misconceptions may affect decision making when designing procedural information.
