Knowledge is transmitted, explored and advanced via language face-to-face, in printed texts, and in other media. Children and their teachers write, read, talk and listen mathematics. Mathematics education begins and proceeds in language, it advances or stumbles because of language, and its outcomes are often assessed in language. Language and Mathematical Educuation presents current perspectives and reviews the key issues. It brings together in one volume work from researchers concerned with various aspects of language in mathematics education. Each contributor provides an account of their research and draws out the practical implications in terms which will inform and guide teachers.
