  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 are 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.
