A key problem in education is that advisers/performance managers/most in a position of assessing schools/heads/teachers are assessing using criteria created by 'Gurus with no field experience'. Check out http://www.linkedin.com/groups/TOP-TRUMPS-State-Education-in-126310.S.69072770
It is no good thinking outside the box if our thinking is still limited by criteria inside the box.
I suggest getting rid of the box containing criteria created by these 'Gurus with no field experience' and start with a clean sheet. You may have heard the expression 'look after the pennies and the pounds will take care of themselves'. An equally true expression is 'look after the learning (ie. get it right) and the exam results will take care of themselves'.
If we begin to educate our students into becoming independent learners rather than force-feeding them to pass exams, we shall produce students wanting to learn (one volunteer is worth ten 'pressed' men) and hence see the improvement all are trying aimlessly to achieve.
