6. Video conference / CERN + FNAL Moderators: 47+18 (42+12), 40 % new Multiple recruiting channels WG VC (Kate  Katharine Leney, Michael, Marzena, Uta) –Manuals for VC for local organisers –Manual and twiki for moderators –Training for mod. at CERN 17.2. Preparation of conference rooms Reward for moderators: T-shirt from the CERN shop (Rolf/Maureen) +

7. Evaluation with CERN moderators Started 3 days ago, 17 answers so far Introduction rated 2.5 (on a 5 point scale) Twiki and manual good resources, some issues can be improved Many technical issues on institutes´ side (bad audio, connecting too late, not muted) Some institutes not well prepared (no speakers selected, no questions collected) Improved setup in rooms at CERN requested, camera angle, screens, … Moderators generally enjoyed the sessions Very detailled feedback on measurements, will be made available

CMS Masterclass 2015 23 countries, 78 institutes Introduced CIMA - CMS Instrument for Masterclass Analysis: Developed July-Feb 2015 by Stefan Schoppmann and Michael Soiron (Uni Aachen), support from QuarkNet and Notre Dame Bugs first week of masterclasses – fixed Rated highly, great results CMS Masterclass very stable with continuous improvement CenterMasterclassesCountriesVideoconferencesLanguages CERN491710 FNAL291011 Combined78232112

14. ALICE : Looking for strange particles - 2015 Masterclasses 14 International Physics Masterclasses (+1 at CERN, school from New Zealand on CERN visit, 7.4.2015) Total ~ 500 participants Newcomers : Maynooth (Ireland), Trieste Feedback positive and enthusiastic Comments on collection of results –from visual analysis : too slow - maybe skip in the future? –google spreadsheets : safe? Extended sheets with statistics to be used in the future Some comments on videconference (sound quality..); too long? Measurement stable - No plans for change Virtual machine used in some cases CERN: used S’COOL lab

15. ALICE: Nuclear Modification Factor l one session on March 13 l ~80 participants at 4 institutes l Darmstadt, Germany l Frankfurt, Germany l Münster, Germany (new this year) l Prague, Czech Republic l same measurement as in previous years: http://www-alice.gsi.de/masterclass/ http://www-alice.gsi.de/masterclass/ l all groups ‘discovered’ the quark-gluon plasma l positive feedback from all groups and moderators of the video conference

18. Totem Masterclass Development Uta demonstrated with coaching from Giuseppe Latino Improvements: More data Data merge Plot histogram in |t| and  Now runs on Windows and Linux Needs further development: More stable Windows version Mac version Next SG Vidyo: How to best use How to move forward
