Analysis of geometric proof texts in school mathematics

Practice of proof is considered in the view of language and meta-mathematics, recogniz-ing the role of proof that is the means of communication and development of math-ematical understanding. Linguistic compo-nents in proof texts are symbol, verbal language and visual text, and contain the implicit knowledge in the meta-mathematics view. This study investigates the functions of linguistic elements according to Halliday's functional grammar and the rhetoric skills in proof texts in math textbook, teacher's note, and student's written text. We need to inquire into the aspects of language for mathematics learning process and the understanding and use of students' language.
