Thoughts about Physics and teaching Physics
Space is my favourite topic in Physics. Not only because all pupils will, in their lives, have looked up at the night's sky and started to wonder, but because Space ties several topics of Physics together into one beautiful, unified whole.
Threshold concepts completely transform one's perception of a subject. In Physics, a key threshold concept is that what we measure on the macroscale is because of what is happening on the microscale.
Pupils struggle with learning Electricity because it is too conceptual. Using analogous circuit models helps them understand the basics. My favourite analogous circuit model is the shopping model, which I explain here.
