Discourse, of Course: Encouraging Genuine Mathematical Conversations
Discourse is one area of the nctm's professional teaching standards for School Mathematics (1991) that causes many teachers particular difficulty. Mathematics teachers have a long history as lecturers. Although “initiation-reply-evaluation” (Richards 1991) sequences between the teacher and students are not uncommon, genuine mathematical conversations are rare in most classrooms (Weiss 1994). Discourse can be a problem area for teachers when they do not realize how important it is and have not seen or experienced dynamic classroom discourse. Once a teacher has seen students defending their mathematical ideas, questioning other students' ideas, and helping clarify the mathematics to one another, the importance of discourse becomes clear.
