Thinking about actions to take: Efficiency and Calculations
Teaching Guidance for 14-16
There's a good chance you could improve your teaching if you were to:
Try these
- using
efficiency
as a technical term, perhaps reservingeffectiveness
for the more general idea of getting stuff done well - using apparatus, words and diagrams together to develop accounts
- developing physical descriptions before accounts that use energy and power
- emphasising the practical consequences of calculations with power and energy
Teacher Tip: Work through the Physics Narrative to find these lines of thinking worked out and then look in the Teaching Approaches for some examples of activities.
Avoid these
- calculating without sharing the purpose of the calculations
- running together different steps of multi-step arguments
- confusing snapshots with processes
Teacher Tip: These difficulties are distilled from: the research findings; the practice of well-connected teachers with expertise; issues intrinsic to representing the physics well.
