Things you'll need to decide on as you plan: Efficiency and Calculations

Teaching Guidance for 14-16 Supporting Physics Teaching

Bringing together two sets of constraints

Focusing on the learners:

Distinguishing–eliciting–connecting. How to:

  • bring calculations back to the lived-in word
  • relate very abstracted descriptions to very practical concerns
  • keep power and energy separate, yet related
  • keep calculations linked to physical concerns, showing what cannot happen

Teacher Tip: These are all related to findings about children's ideas from research. The teaching activities will provide some suggestions. So will colleagues, near and far.

Focusing on the physics:

Representing–noticing–recording. How to:

  • deal with power as that which accumulates energy
  • separate descriptions that link snapshot to snapshot from descriptions of processes
  • construct explanations in careful, explicit steps

Teacher Tip: Connecting what is experienced with what is written and drawn is essential to making sense of the connections between the theoretical world of physics and the lived-in world of the children. Don't forget to exemplify this action.
