Usually, all groups of students work with the same scenario and same data sets. This situation is easy to manage in the classroom and is relatively easy to assess, but it is somewhat artificialanddoesnotmirrorreal-worldproblem solving,where the context and scope of the problem may vary over time. The study described here utilized dynamic problem scenarios in order to simulate a more realistic problem solving experience for students and to develop problem solving skills that more closely resemble those used outside of education. Our new model of PBL, dynamic problem-based learning (dPBL), uses scenarios in which the parameters of the problem change over
time, provide different groups of students with different data sets, or provide different routes through the problem for students. Thus, each group of students will have tackled an individualized problem.
