Abstract:

In sociolinguistics, a register refers to a variety of language used for a particular purpose or in a particular communicative situation. My research team has conducted mathematics education research on a special type of registers, mathematical registers or registers of mathematics (Pimm, 1989), which is a set of meanings, together with the words and structures expressing these meanings in mathematics contexts.  In particular, we focused on mathematical language (especially quantifier words) and mathematical representations (especially graphical representations) in calculus texts. In this presentation, I will illustrate some examples from the studies that my research team has conducted on undergraduate students’ interpretation and evaluation of statements in undergraduate calculus texts, including the Intermediate Value Theorem and the Definition of Convergence of a Sequence. This presentation will also include how students’ meaning of language and representations used in mathematical texts are similar to/ different from mathematical registers. I will also discuss some practical implications of these research to the teaching and learning of undergraduate mathematics.
