Dialogue and Learning in Mathematics Education is concerned with communication in mathematics class-rooms. In a series of empirical studies of project work, we follow students inquiry cooperation as well as students obstructions to inquiry cooperation. Both are considered important for a theory of learning mathematics.
Special attention is paid to the notions of dialogue and critique. A central idea is that dialogue supports critical learning of mathematics. The link between dialogue and critique is developed further by including the notions of intention and reflection. Thus a theory of learning mathematics is developed which is resonant with critical mathematics education.
