Thoughts about Physics and teaching Physics
The A-Level topic of electricity usually involves jumping between the microscale and macroscale, which takes huge cognitive load. Here I propose developing schemes of work based directly on the two length scales. The idea comes from threshold concepts.
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.
Here are common issues and how to overcome them with CPACs in A-level Physics practicals
In my first post I discuss CPACs for A-level Physics. How do we as teachers ensure compliance with the rules.
