Abstract
The visual attractiveness of two Queensland mathematics textbooks is examined. Diagrams
were categorized according to their type, and each type was examined in terms of
perceptual precedence. Series A textbook was found to have one third of diagrams of a
cosmetic type, commanding 40% of the perceptual precedence. Such diagrams have no
relevance to the subject matter, and therefore the potential to distract a student. Series B
textbook was found to have combination diagrams in abundance that demanded perceptual
precedence. Each diagram of this type has two or more functions and the potential to be
effective in developing mathematical understanding. It is recommended that further
research be conducted into student uses and perception of diagrams so as to inform authors
and illustrators.
