Abstract
The purpose of this study was to
compare the structure of
mathematical word problems
which first year pre-service
teachers were able to solve easily,
with those that they found
difficult. The aim was to identify
a hierarchy of problem types to
which student teachers should be
exposed if they are to develop
their mathematical problem
solving skills. Task an,zlysis maps
of twelve word problems given to
fifty-eight student teachers
suggested a progression in the
required level of processing, the
nature of the information stated in
the problem, the extent of demand
on the working memory, and the
type of concepts and processes
required.
