Reviewing lessons from the perspective of the least confident. Are you reaching them?

The thing I find I’m increasingly focused on on my many lessons visits and learning walks is the gap between the general thrust of a lesson, aimed at and involving the most confident students, and the experience of students at the other end of the range. For students in, say, the lowest 20% of attainment, I think day to day school life can be pretty grim. Lessons can go on around them without them feeling that they are part of the teaching and learning flow; they are present but they are being left behind.
