Originally I put this in the "secondary" area but it applies as much to the primary phase as it does to secondary. I came up with this whilst head of a middle school and used the this idea with both our secondary and primary practitioners. I went through OFSTED last year and every single lesson went brilliantly. When I conducted the feedback the teachers led off by evaluating their own lessons and I had little to do (they used the vocab of the 5Ps to structure their evaluation - planning, purpose, pitch, pace and progress). I was inspected by a couple of HMIs who seemed very pleased with this. The year before I had introduced my "5Ps" of what makes a good lesson. It was an approach which asked teachers to think about the key aspects of a lesson before constructing a plan. I have written about it in a blog I write and you can find it HERE . Please feel free to use it if it is of any help. I have also added 2 extra Ps so it is actually now "5 + 2 Ps" and if you are still interested you will find these discussed elsewhere in the same blog. Hope this helps! If you want to know any more please send me a message.
