Amongst Mathematicians offers a unique perspective on ways in which mathematicians perceive their students' learning, the way mathematicians teach, and the way mathematicians reflect on their teaching practice. This is achieved by bringing fictional characters together into a conversation on these issues, wherein the mathematical content is based on large bodies of data. The book develops the analyses further and demonstrates the pedagogical potential that lies in collaborative, multi-laterally engaging research and action in undergraduate mathematics education, an area that desperately needs such action. It contributes to the discourse for reform and demonstrates the feasibility and potential of collaboration between mathematicians and researchers in mathematics education by engaging mathematicians as educational co-researchers. Further, it puts forth a non-deficit discourse on the pedagogy of undergraduate mathematics.
