  16. The Course of Science Sparse and Infrequent Observations Observational Errors Incorrect Interpretation of Observations Theoretical Misunderstanding Management Directives Oversimplified models Computer Models Controversy Further Refinement of Unimportant Details Code Errors Unrealistic Assumptions Crude Diagnostic Tools Confusion Further Misunderstanding Coincidental Agreement Between Theory and Observations Publication Cover Up

  17. Research Project: • Not just another lab • Look for real unknown • Doesn’t need to be really complicated • Web page has examples • Teaching Requirement • Tutor first year student • Present a lesson in class • Teach a lesson in another classroom • Work on Web Tutorial • Physics Parties

  18. Communicating with me • Chris Murray • W:503.431.5721 • H:503.452.0017 • cmurray@ttsd.k12.or.us • http://tuhsphysics.ttsd.k12.or.us • All of this is on the handout
