'Reading' geometrical diagrams: A suggested framework

. Proceedings of the British Society for Research into Learning Mathematics, 28, page 1-6. (2008b)

Abstract

Mathematics is a multimodal/multisemiotic discourse where different modes of communication take place such as verbal language, algebraic notations, visual forms and gestures. These different modes offer different mathematical meaning potentials. Based on Halliday’s SFL, Morgan (1996) has developed a linguistic framework to describe the verbal components of mathematical texts. O’Halloran (2005) also developed a framework to describe the mathematical visual graphs and symbolism. Still, there is a need to develop tools to describe other modes such as geometrical diagrams and gestures. This paper shows only one aspect (ideational/representational) of a suggested framework to read geometrical diagram/shapes which is developed based on school-students' work and textbooks.
