Elementary particle physics is gradually implemented into science curricula at high school level. However, common presentations on educational, semi-technical or popular level contain or support severe misconceptions. We discuss in particular the notion of `particle', the interaction between them and the use of Feynman diagrams. In many cases the true novelty of particle physics (i.e. quantum field theory) is largely ignored. We also suggest reasons for this widespread distortions of particle physics in popular accounts.
Teaching electromagnetism through demonstration of a practical application involving learning content from multiple disciplines: https://arxiv.org/abs/1811.07530
Teaching electromagnetism by demonstrating a practical application associated with learning content is an important teaching technique. Demonstrations are often performed through video-assisted procedures, and are usually limited to a one-to-one correspondence between the application and the learning content. However, understanding of practical applications frequently requires understanding of learning content beyond the ones studied in electromagnetism. I designed a process to teach the working principles of cryogen-free superconducting magnets. Understanding of this practical application requires students to have knowledge of learning content from the disciplines of electromagnetism and solid state physics. The teaching process involved the use of homemade videos demonstrating magnet operation, which was combined with a flipped classroom and an active learning approach.
