The purpose of this paper is to have implications for mathematics teacher education through analysis of mathematician's activities by reading an academic paper.
The result suggests that a mathematician does not only think deductively but also take an inductive and empirical approach while forming hypotheses. It isn't always appropriate to provide academic mathematics papers for undergraduate students because an essential background is needed to read them. However, to read an academic paper could be enough worth for students in mathematics teacher education because they could follow a mathematician's research process including submitting an academic paper and reflect reasons to write the paper.
