Going Beyond End of Chapter Problems in LON-CAPA
  Location: HC 3029
  Date: Monday, Aug.1
  Time: 6:40 PM -6:50 PM
  Author: Boris Korsunsky, Weston High School
  Co-Author(s): Raluca E. Teodorescu , Carolin N Cardamone , Saif Rayyan , David Pritchard
  Abstract: We describe the open-source library of physics problems we are collecting in LON-CAPA ( 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.
