There's a good chance you could improve your teaching if you were to:
developing physical descriptions before accounts that use energy and power
using apparatus, words and diagrams together to develop accounts
emphasising the practical consequences of calculations with power and energy
putting new theoretical ideas to work to imbue them with meaning
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.
replacing the physical arguments with mnemonics
arguing about power and energy without quantifying
conflating different steps of multistep arguments
not making links between different devices, all of which switch power
These difficulties are distilled from: the research findings; the practice of well-connected teachers with expertise; issues intrinsic to representing the physics well.
