by taking responsibility for good teaching because nothing less will do.
you are speaking as if "good teaching" can be defined and measured. It can't.
The definition changes constantly, round and round in circles.
Four years ago text books were written into the SOW, two years ago being caught with a text book was practically a disciplinary offence in itself. Now they are swinging back in.
Four years ago we HAD to refer to ECM EVERY 20 MINUTES during observations, so in a lesson on measuring voltage in a series circuit you HAD to include something on healthy eating etc. two years ago ECM was out and prevent was in, so your lesson on voltage had to include "British Values" so somewhere in the middle of demonstrating how to buid a circuit, you were required to refer to democracy.
Two years ago I hadn't had a working computer in my room for over a year, two weeks ago I was turned down at an interview because I hadn't touched a computer for a whole 20 minutes - unacceptable, apparently.
You can teach, OR you can gather the evidence required for performance management and statistics, but not both.
Five years ago it was fine to speak to a pupil in lessons, you could speak to as many as you liked. Three years ago you had to record what was said to each one, so could only speak to as many as you could record, and spent more time recording than speaking.
Five years ago, you had to write Aims on the board. Three years ago, Aims were banned and you had to write objectives instead. But could still fail an observation if they were not on the board. So that meant you couldn't write anything ELSE on the board during an observation. Some students in local schools organised an "objectives" strike, and put their pens down and refused to pick them up if objectives were written on the board.
who judges what is "right" I've hardly started on the three part lesson.. right, then evil, then right, then evil, now currently right again.
"Educational research" published in the uk, and supported by ofsted, is a load of bollocks dreamt up by people who don't know what the word "research" even means.
Of course you can fail any teacher you want. They are too loud/not loud enough/ talk for too long/ don't talk for long enough/ differentiate too much/don't differentiate enough/ have expectations that are too high/not high enough / are too inclusive/not inclusive enough.etc etc etc etc
An individual is chosen, and hounded out, then another individual is chosen, and hounded out, and so it goes on. 9 times out of 10, the basis for choosing an individual is cost, pure and simple, nothing else.
