Montgolfier measure of educational impact ...
Lets forget all the little ways that inspection regimes like Ofsted attempt to measure the quality of teaching in our national classrooms. There is no proof of effectiveness in the quality of the teaching, only in the schools ability to create a culture that conforms to an inspection regime.
So, with my view of the value of the accuracy (and therefore validity) of an Ofsted observation. I cannot see why we cannot equally apply the "Montgolfier measure of educational impact".
It works on a simple principle, the more hot air a teacher produces. Therefore increasing the likelihood of a hot air balloon rising (hence the Montgolfier measure). The more probable it is that the teacher may have some desirable effect on the students.
Why not, we see teacher centred and student centred around the world and it would seem that they have the same value. So why can we not face facts and accept the signal to noise ratio involved in teaching at all levels.
With all of this due some consideration, I have two questions:
- What do you think your Montgolfier measure is?
- How would you scale such a system?
