In this chapter, the focus is on knowledge representations in different sites of learning. We will give some examples of formal, semi-formal, and non-formal institutional framings, as well as of choices of representational resources—both in terms of designs for learning and play, and designs in learning. The knowledge area is the Middle Ages, a period which reappears in books, music, films, and games in late-modern contexts. This chapter is thereby also an example of learning outside and inside schools, and of how different institutional logics and choices of material resources affect which type of knowledge that is valued, and what is seen as signs of learning.
