1. The Masterclass in the U.S., 2010 Ken Cecire University of Notre Dame/QuarkNet kcecire@nd.edu

2. EPPOG Spring Meeting 16 April 2010 2 Items to Report Statistics and developments Pre- and post-MC results from 2009 Synopsis of changes for 2010 Comparative survey results, 2009-2010 Observations Future plans

3. EPPOG Spring Meeting 16 April 2010 3 2010 (2009) Statistics 22 (23) U.S. institutes 2 Masterclasses with no videoconference 3 participated with CERN rather than FNAL 2 (2) institute(s) from outside U.S. Wien continued. UCL dropped. Added Shizuoka, Japan. 7 (7) videoconferences at Fermilab Each had 2-5 (3-4) participating institutes. >500 (>350) students

4. EPPOG Spring Meeting 16 April 2010 4 2010 Overall Developments Prescribed preparation plan narrowed to 3 hrs. All groups did DELPHI masterclass this year. Migration from wiki to “Masterclass Library” completed Library: http://quarknet.us/library/index.php/Masterclass_Library Second year of rigorous evaluation Student survey and pre/intermediate/post-test Added teacher survey. M.J. Young & Associates with QuarkNet fellows and participating teachers Variations for larger numbers of students Large MC with onsite conference (not video) Baltimore, Brookhaven, and Notre Dame solutions

5. EPPOG Spring Meeting 16 April 2010 5 Changes to Classroom Prep Plan All teachers prep students. Learner objectives Reduced time Hands-on emphasis, 3 activities Rolling with Rutherford Quark Workbench Top quark mass

6. EPPOG Spring Meeting 16 April 2010 6 Additional Changes to Model Orientation for all U.S. institutes All teachers asked to participate. Masterclass day Demo: cloud chamber or e/m apparatus Lunch with physicists MC cheat sheet Videoconference Removed “normal event” presentation from videoconference. Put “questionable events” on Google docs with data. Recruited younger physicists from CMS and DZero as moderators at Fermilab Moved moderation to near Fermilab Remote Operations Center.

7. EPPOG Spring Meeting 16 April 2010 7 Participation Developments Masterclass at Fermilab model For large groups Divided into n teams with n mentors “Non-videocon” held onsite This year at Fermilab, Mayaguez, Irvine Alternative models Baltimore: large MC, 2 videoconference groups Notre Dame: very large MC, select students in videoconference, use of Web 2.0 tools Brookhaven, Mayaguez: more than one MC Addition of Shizuoka, Japan 6:00 a.m. JST videoconference 10 students Language challenge

8. EPPOG Spring Meeting 16 April 2010 2009 Pre-Post Quiz – Overall Result Based on results from 10 teachers with 90 students Pre-test: given before clasroom prep Mid-test: given between classroom prep and MC Post-test: given within week after MC 8

9. EPPOG Spring Meeting 16 April 2010 2009 Pre-Post Quiz – Partial Item Analysis Based on results from 3 teachers with 43 students and large effect sizes compared to others (used to highlight relative effectiveness of questions) 9

11. EPPOG Spring Meeting 16 April 2010 Surveys – Attitudes 11

12. EPPOG Spring Meeting 16 April 2010 Surveys – Program Aspects 12

13. EPPOG Spring Meeting 16 April 2010 Surveys – MC Effect on Interest in Physics 13

14. EPPOG Spring Meeting 16 April 2010 Observations 2010 Classroom preparation materials Gave teachers hands-on resources. Level of use improved. Pre/intermediate results show gains. Meeting goals Students learning particle physics Exercises still popular Tours and lectures also did well in 2010 (improved?). Videoconference from FNAL Less successful than 2010 New moderators did well; gave good feedback. Balance opportunity for discourse with structure. Large group adaptations “MC@FNAL” model was disappointing in 2010. Other adaptations seemed to work better. 14

15. EPPOG Spring Meeting 16 April 2010 Plans Growth Did not seek growth in U.S. numbers in 2010. Grew anyway. Must plan 2011 with growth in mind. Increase internationalization Find new ways to integrate with Europe. Follow up with Japan. Follow-on Videoconferences with students Use of social media 15
