1. The "teachers" have access to unrealistic budgets and facilities. To help making drama more real they get to use the Globe theatre stage and to teach history they use part of the Anglo-Saxon horde.
2. They appear to have one class to deal with rather than 5 classes per day, 5 days a week
3. By introducing the cameras they behaviour of all is fundamentally changed. Some kids will improve as they don't want to look like an idiot whilst others will see it as opportunity to play up to the cameras (if they are really noticeable this might lead some doors opening in other places)
4. After a while everyone leaves and the support and interest fades, a lot of these issues can't be addressed in a short-term piecemeal approach.
I suppose there is a bit of annoyance on my part. I have been to restaurants but won't lecture Jamie on how to run a kitchen/ restaurant and I guess I don't like the arrogance of people who think because I went to school once I can successfully teach a group of children. My hope is that at least one kid benefits from the experience.
