Sandefur et al. (2013, p. 324) wrote that Iannone et al. (2011) “concluded that ‘simply asking students to generate examples about a concept does not improve their abilities to write proofs about that concept…’ (2011, p. 10).”

This was a misquotation. The original passage read: “To avoid misinterpretation, our studies do not imply that example generation must necessarily fail as a pedagogical technique to increase students’ understandings of mathematical concepts. However, they do demonstrate that simply asking students to generate examples about a concept may not substantially improve their abilities to write proofs about that concept, at least not more so than providing students with examples to read.” (Iannone et al., 2011, p.11).
