Agree! In one school I worked in (v small indie) the Principal would observe me and all would be good. Then he'd say 'in MFL we do it like this'. I'd answer 'But this is not MFL this is Science and we do it this way'. Observers are like OFSTED inspectors......they have to find fault to justify their existence. Do doctors get observed? Lawyers? Engineers? Dentists? Policemen? No...................so why teachers all the frickin' time!!!!
