Abstract
Two collaborative groups of senior secondary mathematics students with similar ability to
solve unfamiliar challenging problems demonstrated different· levels of engagement and
different levels of conceptual development when they worked with the same task. Study of the
nature of task complexity led to the formulation of discovered complexity as a useful tool to
analyse student response to tasks. It was found the task undertaken provided the opportunity
for discovered complexities that possessed the potential to enhance student learning. Use of
such a task was found insufficient to ensure discovered complexity resulted.
