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 14.07.2016 4
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 14.07.2016 5
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) 14.07.2016 6

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 http://ippog.web.cern.ch/ 14.07.2016 15
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 14.07.2016 16
and how it has grown since then 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 18 countries 46 58 institutes 213 72 masterclasses 276 3k students 13k 12 video conferences 75 14.07.2016 17

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 ) 14.07.2016 19
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 ) 14.07.2016 20
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. 14.07.2016 21
Netzwerk Teilchenwelt Multi-level program for high school students, aged 15-19 teachers/trainers At schools, school labs, science centers, museums ~200 events p.a. 26 research labs in Germany + CERN Central organization: TU Dresden www.teilchenwelt.de 14.07.2016 22
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 14.07.2016 23
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 14.07.2016 24
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 14.07.2016 25
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. 14.07.2016 26
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 2017 14.07.2016 27
More Material Web pages for students Hosted on Largest German Physics Portal for schools Relaunch of particle physics section 2014 www.leifiphysik.de/themenbereiche/teilchenphysik Supporting material for facilitators and teachers Particle Profiles Background information and worksheets www.teilchenwelt.de/material/materialien-fuer-lehrkraefte/ 14.07.2016 28
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 14.07.2016 29
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 14.07.2016 30
