Abstract
This paper reports analysis of the concept maps of the understanding of function developed in secondary school constructed by seven experienced secondary mathematics teachers who were part of a larger study. The concept maps were analysed according to (a) key notions related to the definition of function, (b) process or object view of function, and (c) identification of the importance of working within and across representations. The findings suggest a teaching emphasis that might not be supportive of students developing a deep understanding of functions.
