### Abstract

This paper reports on students’ ability to decode mathematical graphics. The findings were:

(a) some items showed an insignificant improvement over time; (b) success involves

identifying critical perceptual elements in the graphic and incorporating these elements into

a solution strategy; and (c) the optimal strategy capitalises on how information is encoded

in the graphic. Implications include a need for teachers to be proactive in supporting

students’ to develop their graphical knowledge and an awareness that knowledge varies

substantially across students.
