  Abstract: We consider physics problems that require students to combine their existing resources in new ways. When students do this in the context of integration and differentiation, they have many procedures, concepts, and representations to choose from. In addition, they may have varying degrees of understanding about the procedures they invent. We examine students' resource selection in problem solving situations, using an online environment to control and monitor their progress through a series of hints. Over the course of a 30-minute testing period, students work through a single problem; initially inventing their own strategies, then following our suggestions toward particular solutions. We will present results from our assessment of students' na├»ve understanding, as well as the impact of cues and training after a 50-minute practice session prior to the test. We will also describe students' ability to learn new ways of thinking about the problem.
