I'm very grateful to Simon Ross, because I have to admit that I didn't understand Siobhan's question, for much the same reason that he suggests.
As I understood it, AfL - Assessment for Learning - was originally all about the
assessment process of getting to pupils to understand why - in a particular assignment, piece of classwork or assessment piece -they had gained the level they had gained, and what they needed to do to advance to the next level. At thsat time it was essentially something that the teacher did on his exercise books, after the lesson was finished. We started highlighting 'passages that demonstrated the level' when we were marking, and adding 'Ways you can improve' after we had marked each piece of work. I have to admit, that WAS a hell-of-a-sight better that 'try to work more neatly next time'.
Then - again
as I understood it - AfL then became all linked up with the idea of a plenary, because that was when the teacher assessed the progress made by the pupils, and used that information to make sure that his next lesson was the relevant next step for the pupils in the class. Thus AfL became part of the process of lesson planning, because it was informing the best way to prepare the next lesson(s).
And the latest I had heard - again
as understand it - was that you had to do mini-plenaries throughout your lesson, so that you could make sure that not only was the next lesson the next step, but that the next step in the lesson was the right 'next step' for the pupils. By this, AfL was being integrated into the TEACHING process, because it was something the teacher was doing to guide his teaching throughout the lesson.
Nevertheless, even though we were seeing a developing concept, the concept of AfL was of something which SUPPORTED the children's learning - something which you applied TO your lesson plan.
I have never before heard of the idea of an AfL lesson
per se - an AfL lesson for AfL's sake!
So was Siobahn being asked simply to teach a normal lesson, but just one where she would demonstrate that she was using AfL principles in the marking, the planning and the delivery of her lesson (as above) ... or had the concept of AfL had moved on, and that now we were supposed to be able to teach 'AfL LESSONS'!
I mean, there are lots of very ambitious people out there making a good living from delivering training about this, and it pays them to keep on inventing new things for us to have to 'learn' how to do!!! So - is there such a thing? From Simon's post he seems mere to be describing what I have always called a three-part 'Secondary Strategy' lesson, and CALLING it an AfL lesson. Have we started doing this now? Or is an AfL lesson something different? Or does Siobhan need to go back to her HoD and ask what he means by an AfL lesson??
Genuinely not being sarcastic here ... things move on and its very easy to get left behind.
Reading Siobhan's post made me worry that it had happeend to me.
