Session Type: Symposium
The professional vocabulary of mathematics teachers profoundly shapes their teaching and their capacity to reflect on their practice. The International Lexicon Project documents the naming systems (lexicons) employed by nine different communities speaking eight different languages to describe the phenomena of the mathematics classroom. In this symposium, we report the lexicons of Australia, Chile, France, Japan and the USA and compare these lexicons with respect to the key characteristics of agency, and the relative focus on form or function. Each lexicon contains the encrypted pedagogical history and cultural norms of its community and provides the essential tools for teacher action and reflection. Comparison of these lexicons can be mutually informing, offering important insights into relative emphases and omissions.
