I don't know about anyone else, but I hear this work bandied around a lot when we approached inspection and when we have lesson observations for one reason or another. I got this feedback recently. The lesson was lovely. The behaviour was spot on. The children were all engaged. You gave a good solid lesson with no poor points, but you didn't sparkle. What is this mysterious quantity? I've never had the nerve to ask HOW to go about learning to sparkle. My class can be boisterous and silly, so I foster a really calm manner with my classes as I find it helps calm them in return. If I 'sparkled' then I think the behaviour would slip with some of my more immature ones. Is it a phrase that can't be quantified? Do I care? I want to be a good teacher and am.
