I was told this week that Ofsted will deem a lesson unsatisfactory if as few as 2 out of 30 children are not fully engaged in a lesson - e.g. swinging on their chair or talking. How in the world can you ensure that *every* child is engaged, for the entire lesson, when you're teaching children who are constantly on report, in trouble with every teacher, having regular detentions from Heads of Year, etc. Some children just do not want to learn, and if you've been unable to hook them into your subject, even the most exciting, engaging lesson will be pointless - if only because they'll take things too far and use it as an excuse to show off and be silly. Can Ofsted really be this petty?
