Thinking about actions to take: Efficiency and Calculations

There's a good chance you could improve your teaching if you were to:

Try these

• using efficiency as a technical term, perhaps reserving effectiveness 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.
