I haven't been teaching very long, but I have heard about the different variations of teacher observations during the years. Veteran teachers and administrators I've talked to say it allows the administrator multiple opportunities to get inside of the classroom. The flip side is, administration does not have time to do a whole lot else. A principal with over 50 teachers having to do 2 walk throughs and a 30 minute summative is a lot. Imagine those who have more than that! Is this requirement too much, and should the start revisit it to make adjustments?
It seems that there is no real solution to this yet.
