For a start, you are working in a job where you can't choose your raw materials. A BMW designer specifies his bodywork, engine, paint and tyres.
No matter how carefully you design your lesson, your raw materials will just arrive randomly and there's no chance of a pre-delivery quality check.
You don't even get the chance to sign for them, or better still send them back. Your lesson just has to be planned to suit some gleaming chrome and a rusty chassis.
More seriously, if you are going to be the teacher they all remember, you're going to take risks and that means lessons that go wrong. The alternative is to be the sort of Ofsted-approved automaton you watch in the training videos. (Be honest, did you concentrate when you were supposed to be noting the good bits and the things that could be improved?) Anyway, when you want to plan and reflect, stay focused on what matters: l Don't be afraid to take risks l Plan your lesson - not your lesson planl Be honest with yourself - was it you or was it them? l What constitutes a good lesson is as much subject to fashion as fashion.
