Abstract:
|
We describe the open-source library of physics problems we are collecting in LON-CAPA (http://loncapa.mit.edu). Currently, the library features both traditional and research-based problems intended to expose students to various contexts, problem features, knowledge and cognitive processes. We are adding conceptual questions and challenge problems that require out-of-the-box thinking. The conceptual questions were developed at Ohio State University and MIT. The challenge problems are inspired by various tasks published in The Physics Teacher. 1-3] We are planning to evaluate the difficulty and pedagogical effectiveness of those problems using Item Response Theory (IRT). This permits determination of a student's skill independent of which problems they do. We welcome collaborators willing to add their problems to our library.
