Researchers have studied and reported on student problem solving in the sciences for nearly a century. From this body of work, methodologies devised to study problem solving have been as diverse as the variables measured and outcomes of the studies themselves. This presentation describes the application of decision theory to interpret problem solving processes. Decision theory will be described, as well as its potential methodological application toward problem solving studies. Constructs related to the process of solving problems, such as procedural and content knowledge, have been investigated with success using decision theory. Methodological development of the theory is ongoing; future directions will be discussed as well.
