4 Bringing Particle Physics to the Classroom Strength and Chances Fundamental questions Fascinating terms, e.g. Big Bang, Antimatter Unique and fascinating experimental setups Strong presence in the media Challenges Modern physics often not in curricula Many new concepts and perceptions Large number of new terms Connection to everyday experience

5 Particle Physics Masterclass As in a masterclass in the arts, students work with an expert Expert = particle physicist Instead of, say, a violin, the subject is particle physics data analysis

6 Concept of IMC High school students (15 19) are scientists for one day Get invited to a research institute or university Introductory talks (standard model, detectors, accelerators) measurement with LHC data International video conference (3-5 inst. + CERN/Fermilab) also for teachers (extra MC or inclusive)

7 What is a Masterclass?

8 LOCAL TIME: ACTIVITY: 8:30-9:00 registration & welcome 9:00-10:00 introduction to particle physics 10:30-11:30 second talk or tour 12:00-13:00 lunch 13:00-15:00 data analysis Sample Agenda 15:00-16:00 local combination + discussion 16:00-17:00 video conference with CERN or Fermilab

9 Data from all Experiments

10 Masterclass with ATLAS Data Higgs signal excess at small angles Decay of W bosons (charge asymmetry) proton (uud)

11 CMS Measurement 3D event display (ispywebgl) Students identify W, Z, and Higgs candidates Create mass plot of standard model particles that decay into 2 leptons, plus Higgs Ratios W+/W-, e/

12 Video Conference Video conference 5 groups + CERN Combination and discussion of results Q+A Quiz In English!

14 International Masterclasses countries involved /index.php?cat=country Coord.: QuarkNet / TU Dresden 43 institutes 48 Masterclasses 21 video conf. with Fermilab 1,183 students 128 teachers 169 institutes 228 Masterclasses 54 video conf. with CERN 11,777 students 1,098 teachers

15 IPPOG International Particle Physics Outreach Group Network of scientists, science educators and communication specialists Working in informal science education and outreach for particle physics Representatives from 27 states (incl. 21 CERN member states) + DESY, Fermilab + 5 major CERN experiments IMC = key acitivity

16 How it all began Idea from UK, 1996 (R. Barlow et al.) 1997: 1. Masterclass in UK with 7 institutes 1998: Nationwide uptake 2005: Adopted by EPPOG/IPPOG for all Europe Use of LEP data OPAL Identifying Particles DELPHI Hands on CERN 2006: U.S. joined program (QuarkNet) 2011: LHC-based Masterclasses only 2014: All 4 LHC experiments

17 and how it has grown since then countries institutes masterclasses 276 3k students 13k 12 video conferences

18 Number of Students per Country (CERN VC)

19 Key Features of IMC High school students (and teachers) are scientists for one day As close as possible to current research Own hands-on activities Use the same methods and tools like scientists Direct contact with (young) physicists impact? (on teaching, learning, education )

20 Variety of Approaches IMC: central coordination, but organized individually Many models: Often: one-day-acitivity (expect positive temporary effects, but no long-term effects) Also possible: preparation, follow-up (students prepare videos, essays, give talks, additional activities )

21 Examples teachers training (2-3 days) include MC The teachers usually like this session very much because it complements nicely the didactic (and abstract) courses they follow during the training. Their feedbacks are very positive, just like those from the teachers who come with their students for a regular Masterclass session. Orientation + preparation We provide orientation for the teachers and expect them to participate in the Masterclasses. We do have evidence that when teachers prepare students with at least 3 activities prior to the Masterclass, they do better than students who are not prepared

22 Netzwerk Teilchenwelt Multi-level program for high school students, aged teachers/trainers At schools, school labs, science centers, museums ~200 events p.a. 26 research labs in Germany + CERN Central organization: TU Dresden

23 Four Levels of Activities Research projects -Workshops Project weeks at CERN Research Projects CERN Training and Workshops at CERN Active contributions Proliferation of experiences School projects Qualification Active contributions Running own projects Masterclass participation (Particle Physics, Astroparticlephysics, International Masterclasses) Basic Participation in introductory events Students Teachers

24 Astroparticle Activities Scintillator experiment CosMO and Kamiokanne Loan to schools (after teachers training) Variety of measurements: Angular distribution Coincidence Muon lifetime (2 signals within 20 μs) Study particle showers DAQ board Photomultiplier Scintillator Cloud chamber sets Web experiments (Auger data) International Cosmic Day

25 CERN Workshops + Project Weeks Students 60 s. in two annual workshops (3 days) 10 s. in project weeks own research projects, e.g. Medipix detector, CLOUD, ATLAS trigger system, lifetime of the B- meson, LHC beam steering, ASACUSA, track finding Teachers 40 t. in two annual workshops (5 days) Big motivation for activities Very effective training for teachers in modern physics

26 Alumni > 100 participants of CERN workshops Yearly meeting Own activities Evaluation in July 2014: 2/3 studying physics Consolidated decision to study physics: NTW helped me a lot in deciding to study phsics. I learned how exciting physics can be, outside of school

27 Development of Teaching Material Particle physics for schools, comprising 300 pages of texts, exercises and work sheets on: Interactions, charges and particles Research methods in HEP Cosmic rays Micro courses (stand alone topics) 2 volumes released, 2 more to follow Printed and distributed to teachers Training for teachers starting in

28 More Material Web pages for students Hosted on Largest German Physics Portal for schools Relaunch of particle physics section Supporting material for facilitators and teachers Particle Profiles Background information and worksheets

29 Evaluation of Basic Programme (MC) Method: Structural equation modelling Questionnaire, 5-point Likert scale 500 students + control group Questions: Students interest in particle physics Perception of the event Pre MC Post Follow up 4-6 hours 6-8 weeks

30 Evaluation Results Perceived event features have a relatively strong influence on the students long-term interest development in particle physics Success group (25 %) with a high interest in doing particle physics beyond the MC Independent on gender and level of education Event features (e.g. authenticity, challenge) are rated better Group realizes intended actions of interest format of the Masterclasses seems to be able to sustain interest independently from gender and class or school form
