Abstract
This paper reports the preliminary results of work undertaken for a thesis project
on control-related aspects of mathematical problem solving. The study uses a
non-routine mathematical problem as the focus for the development of problem
solving profiles which summarise subjects' knowledge, beliefs and attitudes
towards mathematics and problem solving, and uses a protocol parsing technique
developed by Schoenfeld to illustrate control behaviour observed during a thirty
minute think aloud problem solving session. Discussion focuses on the protocols
of three sets of subjects and their achievement on the non-routine problem. The
reliability of the parsing technique, and the appropriateness of a think aloud
methodology are also considered.
