Teaching Mathematics with Audiograph

Mathematics teachers are charged with the task of teaching children not only how to solve problems, but also how to explain their solutions. There is, however, very little pedagogical support for this enterprise, and very few tools that support the process. We argue that mathematical explanation is essentially a multi-modal activity, requiring the integration of several modes of discourse, and that learners need tools capable of capturing such discourse in ways that can be edited and developed. The Audiograph system is proposed as a possible candidate for this, some experiences of using this with students of mathematics are introduced, and the potential for future work discussed.
