My first reaction watching this was the class size. 24? Oh I wish! Should have had a standard class size, which for me is never below 30.
Mixed ability is a bad idea, we've just moved to entirely mixed ability for KS3, and the brightest suffer the most in that system.
I like the coloured cup idea, and the whiteboards are used already in our school.
The maths teacher needs support to improve, her manner with the children is too fast, she's assuming they understand and moves on too quick. I was cringing at her style of teaching.
The exercise in the morning is a nice idea but totally unworkable for a whole school.
Some of the questioning technique that the teachers used needs looking at, majority are asking closed questioning, which is recognised as being negative and confrontational. They need to adopt a better form of open questioning before they introduce all the gimmicks. The lolly sticks are an interesting way of opening up the class more, but I would have thought a good teacher already does that.
Was this Dylan an ex teacher himself? We often find that those who come in to consult on teaching methods are usually non teachers, which for a lot of staff, turns them off immediately.
Will be interested to see how this pans out next time.
