Query: Long-term impact of a primary school intervention on aspects of
  Einsteinian physics   The physics that underpins modern technology is based on Einstein's theories
of relativity and quantum mechanics. Most school students complete their
compulsory science education without being taught any of these Einsteinian
concepts. Only those who take a specialised physics course have the opportunity
to learn modern physics. In 2011, the first study of a modern physics teaching
intervention with an Australian upper primary (aged 10{11) class was conducted.
The initial intervention was the first step of the Einstein-First collaboration
towards challenging the current paradigm of Newtonian teaching in schools. It
was found that modern physics concepts could be taught to these students. In
2020, 11 participants of the initial study (out of a total of 26) were
contacted for a follow-up questionnaire and interview to investigate any
long-term impact. The results of the follow-up indicate that the intervention
maintained a positive impression on participants. The models and analogies used
during the six-week intervention were highly memorable. The participants
indicated that they found the intervention to be beneficial to their future
learning. Even close to ten years after the intervention, the participants
remembered several key concepts (such as curved space-time). The long-term
follow-up indicates that Einsteinian physics can be taught at the upper primary
level and be recalled several years later.
