Argumentation below expectation: A double-threefold Habermas explanation

Teaching mathematical argumentation is a challenging task, and how to teach argumentation to students from all backgrounds remains an open question. It is especially difficult to say why some situations evoke the vivid exchange of arguments, while other situations completely fail to engage students in argumentation. This paper points out how two related concepts from Habermas' theory of communicative action may help to explore possible barriers and obstacles to argumentation: The rules of discourse ethics for argumentation processes, procedures and products and the consideration of ra-tionality from the epistemic, the teleological and the communicational perspective. Both approaches help to recognize that mathematical argumentation requires more than mathematical content knowledge.
