Material Mediation: Tools and Representations Supporting Collaborative Problem-Solving Discourse
Katic, Elvira K.; Hmelo-Silver, Cindy E.; Weber, Keith H.
International Journal of Teaching and Learning in Higher Education, v21 n1 p13-24 2009
This study investigates how a variety of resources mediated collaborative problem solving for a group of preservice teachers. The participants in this study completed mathematical, combinatorial tasks and then watched a video of a sixth grader as he exhibited sophisticated reasoning to recognize the isomorphic structure of these problems. The preservice teachers used a variety of material tools to solve the same problem, construct explanations of the learning processes that the sixth grader engaged in, and pose further questions about the problem to clarify their solutions. The results of this study suggest that simple material tools helped to motivate and mediate the participants' collaborative problem-solving discourse.
