So the big idea is to introduce your lesson by relating back to the previous lesson. And to close your lesson by getting the students to reflect on the days lesson and to think about the next day's lesson. The introduction part I can understand fine. But the closure part sounds easier than it is. The main problem I see with closure is that you can try your best to predict how a lesson will turn out and how long it will take. But you have to adjust on the fly and at times you do not have the allotted time for closure. This is especially true for high school and multiple periods. Every class doesn't operate exactly, especially the individual practice portion that comes before the closure. I find that some of my periods can finish that individual practice easily and faster than others. The ones that are slower, they don't have enough time to do the practice. I guess I'm bringing this up because I had an administrator do a formal observation on me today. I think I did well but of course there wasn't enough time for a closure. It was a shorter day too since we had a staff meeting. I don't get feedback until my meeting tomorrow with the admin but I'm curious if closure is that big of a deal from an administrative point of view.
