Wiener, Gerfried J.; Schmeling, Sascha M.; Hopf, Martin – European Journal of Science and Mathematics Education, 2017
This paper describes the second in a series of studies exploring the acceptance of the subatomic structure of matter by 12-year-olds. The studies focus on a novel learning unit introducing an atomic model from electrons down to quarks, which is aimed to be used at an early stage in the physics curriculum. Three features are fundamental to the…
