This seminar will be an exploration and conversation about teaching problem solving. Physics teachers often talk about teaching problem solving as if everyone knows, and agrees, about exactly what is meant, why we do it and how to do it. Working from a broad overview of problem solving research I wish to question any and all such assumptions. Among the questions I will raise are: What is a problem? What does it mean to teach problem solving? What do we hope to accomplish by teaching problem solving? What are problem-solving skills and how are they taught? Does requiring students to work typical end- of-the-chapter 'problems' promote conceptual understanding? If yes, how? If no, why not?
