When it comes to research design, the literature largely focuses on prescriptions for strengthening causal inference--identifying confounders, selecting appropriately comparable cases, generating testable hypotheses, etc. This approach to research design features the logic of inquiry heavily, but overlooks the logic of discovery. The logic of…

In our science for non-science majors course "21st Century Physics," we investigate modern "Hubble plots" (plots of velocity versus distance for deep space objects) in order to discuss the Big Bang, dark matter, and dark energy. There are two potential challenges that our students face when encountering these topics for the…

We have designed model-development sequences using a common context to provide authentic problem-solving experiences for first-year students. The model-development sequence takes a model-eliciting activity a step further by engaging students in the exploration and adaptation of a mathematical model (e.g., procedure, algorithm, method) for solving…
