Engineering Cognition: A Process of Knowledge Acquisition and Application

  • Chapter

Part of the book series: Innovations in Science Education and Technology ((ISET,volume 24))

Abstract

As an integrative and broad field, engineering incorporates many aspects of science, technology, and mathematics fields as well as social sciences. Engineers are often required to develop solutions to design problems in novel situations, with incomplete information and competing criteria. Design, one of the facets of engineering, is a process of managing this ambiguity and complexity through recurring knowledge production. In this chapter, we describe engineering cognition as the interaction and iteration between acquiring knowledge and applying knowledge. It is a novel problem, a novel context, a novel set of users, or combination of these that necessitates knowledge production at the heart of engineering. A challenge in the translation of this model of engineering cognition into teaching is the separation of acquiring knowledge and applying knowledge as two discrete activities rather than a united effort. In this chapter, we present a cohesive model of engineering cognition and discuss how this model can guide teaching, assessment, and curriculum design. Our arguments are built on prior research on teaching and learning engineering in both undergraduate and precollege education. The chapter concludes with recommendations for educators and researchers specifically focusing on the interaction between knowledge acquisition and knowledge application in the context of engineering design problems.
