Here is my knee-jerk reaction.
1) If you believe
'Education is what you remember when you've forgotten what you've learnt'
then measuring and rewarding teachers on any short term criteria is
impossible. I am a disciple of Elliot Jaques, who preached that in any job there
is a 'felt fair' reward that can be arrived at by private discussion with the
individual 2 above her/him in the hierarchy, based on annual report by
immediate superior. Thus: Head of dept reports on individual teacher, who
then discusses report with School head on one-to-one basis.
2) We have neglected to our cost the distinction between further & Higher
education. I assert we should spend more on further, & less on higher.
Students and politicians conspire to favor Higher because (a) it's much
cheaper to lecture to 100 + students than to supervise them in hands-on
experience in a workshop & (b) the snobbery of having a degree. Result:
unemployed engineering graduates, while plumbers are in a sellers' market.
