The term "learning design" is gaining momentum in the e-learning literature as a concept for supporting academics to model and share teaching practice. Its definition and composition is evolving, and as such, there is currently no standard mode of representation for learning designs in education. Instead, there are several emerging learning design representations with different perspectives about their purpose. This chapter explores these issues and presents a summary of the current discourse about learning designs. The aim of this chapter is to address a gap in the literature by comparing and contrasting six learning design representations. The chapter discusses the research conducted to date about learning design representations and concludes by proposing a pathway for further research.
