  Abstract: How do students combine their existing resources and invent new strategies when facing a challenging physics problem? In our study, we examine student use of resources and transfer of problem-solving skills in the context of differentiation and integration. Physics problems that use integration and differentiation require students to coordinate their understanding of mathematics as well as physics concepts, procedures, and representations. After a 50-minute tutorial session, students work through a challenging physics problem over a 30-minute testing period. By using an online environment to control and monitor their progress through a series of hints, we assess their use of resources and the impact of hints and previous learning. We also compare students' performance under different preparations by giving different tutorial materials prior to the testing period.
