Problem solving is a preferred activity teachers choose to help students learn concepts. At the same time, successful problem solving is widely regarded as a very good indicator of conceptual learning. Many studies have provided evidence that problem solving often improves students? chances of learning concepts. Still, the question remains relatively unexplored as to how this activity is useful to promote concept learning. In this study we explore this question in the setting of three university students solving a problem on hydrostatics, in which the concept of buoyancy is involved. We use Coordination Class Theory to study how these students progress on their conceptual understanding. We were able to describe how this progress is related to contextual traits, as well as to students´ particular epistemic stances. Finally, we discuss some implications for research and for teaching.
