Abstract
Current curriculum initiatives in mathematics call for the development of classroom communities in which communication about mathematics is a central focus. In these proposals, mathematical discourse involving explanation, argumentation, and defense of mathematical ideas, becomes a defining feature of a quality classroom experience. In this paper we provide a comprehensive and critical review of how mathematics teachers deal with classroom discourse. Synthesising the literature around a number of key themes, we critically assess the kinds of human and material infrastructure that promote mathematical discourse in the classroom and that allow students to achieve desirable outcomes.
