This paper is part of an ongoing series of projects in which we are investigating "threshold concepts": concepts that, among other things, transforms the way a student looks as the discipline and are often troublesome to learn. The word "threshold" might imply that students cross the threshold in a single "aha" moment, but often they seem to take longer. Meyer and Land introduce the term "liminal space" for the transitional period between beginning to learn a concept and fully mastering it.
