Notes
1. I was disappointed to see little or no discussion of the small but growing literature on the reading of (rather than the construction of) mathematical proofs. Reading proofs seems to be a critical (but under-researched) aspect of how students engage with higher-level mathematics. It also seemed strange to omit discussion of influential papers by Weber (Citation2001, Citation2008) and Stylianides (Citation2007).
2. A further problem for R&K's characterisation comes from Balaguer's surprisingly compelling argument that platonism and “fictionalism” (similar to R&K's description of social constructivism) are, in fact, the same philosophy (Balaguer Citation2008).
