Using video to evaluate student teachers in the classroom

I have just been reading about this 'new' idea - using video to evaluate the student teacher in the classroom situation. This article is from the States.

Here in NZ this is something we used to do and also something we used to get students to do for their own personal critique. Students found that they learnt a lot watching themselves teaching although many couldn't believe it was 'really them' they were watching. The advent of the Flip video, ipod touch with camera and the like make access to videoing and editing assessible. Now many NZ schools do not like our students using videos in the classrooms due to the New Zealand privacy laws.

In some states in USA the students will have:

"more demanding requirements to receive their teacher license: Under a new
teacher evaluation system being tested in 19 states, evaluators will watch video
clips of student teachers delivering lessons in their classroom, and candidates
must show that they can prepare a lesson, tailor it to students of different
abilities, and present it effectively."

These assessments are made by independent evaluators rather than the Teaching Colleges. It will be very interesting to see how this goes. As one professor said:

“It’s a big shift that the whole country is going through,” said Misty Sato, a University of Minnesota education professor who is helping to adapt the assessments for Minnesota. “It’s going from ‘What has your candidate experienced? to what your candidate can do.”

I am very strongly of the view point that our graduates need to know both about and how to teach. I wonder, if in the present environment, some feel that the theory (about) is more important than the practical (how) i.e. the 'about' rather than the 'how'. We are in the middle of changing our courses and are now lecturing in mass lectures rather than smaller classes (where people are able to model behaviours that can be used in a classroom).

Seems that those in the states have now gone through most of this circle and are bringing more 'how' back into their courses. I saw a newsclip in Sydney two years ago on the same thing - 'we think it would be beneficial for our students to have time in classrooms rather than lecture theatres' was the the person being interviewed said. We are not up to that realisation yet, I wonder how long it will take us?
