After all my years teaching in state schools, if you'd asked me what the greatest single problem teachers faced was - you would probably not have been close.
'Change for change’s sake' was the unmitigated disaster in the system.
The so-called 'modernisers' worked to an agenda of 'change = improvement'. (Not wivart finkin' it don't!)
Too many other areas controlled by government were forced to work against 'changes' in order to try to make a rickety, often impossible system work!
