To narrow the research-practice gap, CERN's PER team frequently publishes dedicated articles for teachers and educators. These short papers are intended to make our latest research results accessible to practitioners and provide them with research-based suggestions for the classroom. Below, you can find our latest publications for teachers and educators.


altBend it like dark matter!

Abstract: Dark matter is one of the most intriguing scientific mysteries of our time and offers exciting instructional opportunities for physics education in high schools. The topic is likely to engage and motivate students in the classroom and allows addressing open questions of the Standard Model of particle physics. Although the empirical evidence of dark matter links nicely to many standard topics of physics curricula, teachers may find it challenging to introduce the topic in their classrooms. In this article, we present a fun new approach to teach about dark matter using jelly lenses as an instructional analogy of gravitational lenses. We provide a brief overview of the history of dark matter to contextualise our presentation and discuss the instructional potential as well as limitations of the jelly lens analogy.

altA functional 3D-printable magnet model of the ATLAS toroid

Abstract: The ATLAS detector is the largest particle detector at the LHC and one of the most complex machines ever built. It allows precise measurements of particles emanating from proton collisions. Due to its complexity, introducing the ATLAS detector in the high-school physics classroom can be challenging. Nonetheless, we show how to use 3D printing to provide a hands-on classroom activity by constructing a functional 3D model of the toroidal ATLAS magnet system. This model can be used to discover, visualize and explain the shape of a toroidal magnetic field and to start a discussion about the role of magnetic fields in particle detectors in general.

altTrack inspection: how to spot subatomic particles

Abstract: Although bubble chambers are no longer the technology of choice for particle physicists, they can still enrich the discussion about particle physics in the classroom. We have developed several activities for advanced high-school students, in which they study bubble chamber photographs and analyse tracks of high-energy particles. For example, students interpret the curvature of particle tracks in magnetic fields and learn how to identify different types of particles.

altLet’s have a coffee with the Standard Model of particle physics!

Abstract: The Standard Model of particle physics is one of the most successful theories in physics and describes the fundamental interactions between elementary particles. It is encoded in a compact description, the so-called 'Lagrangian', which even fits on t-shirts and coffee mugs. This mathematical formulation, however, is complex and only rarely makes it into the physics classroom. Therefore, to support high school teachers in their challenging endeavour of introducing particle physics in the classroom, we provide a qualitative explanation of the terms of the Lagrangian and discuss their interpretation based on associated Feynman diagrams.

altIntroducing 12 year-olds to elementary particles

Abstract: We present a new learning unit, which introduces 12 year-olds to the subatomic structure of matter. The learning unit was iteratively developed as a design-based research project using the technique of probing acceptance. We give a brief overview of the unit's final version, discuss its key ideas and main concepts, and conclude by highlighting the main implications of our research, which we consider to be most promising for use in the physics classroom.

altIntroducing the LHC in the classroom: an overview of education resources available

Abstract: In the context of the recent re-start of CERN's Large Hadron Collider (LHC) and the challenge presented by unidentified falling objects (UFOs), we seek to facilitate the introduction of high energy physics in the classroom. Therefore, this paper provides an overview of the LHC and its operation, highlighting existing education resources, and linking principal components of the LHC to topics in physics curricula.
