Abstract
The research reported in this paper represents one component of a larger project addressing
the consequences and implications of the use of a new class of open-ended mathematical
tasks called "Good Questions", devised by Sullivan and Clarke (199Ib). The particular
characteristics of this type of task are the content-specific focus. and the opportunity for
answers at different levels of sophistication. An extended research program is underway to
investigate the use. of this form of open-ended mathematics task for instruction and
assessment in mathematics.
