REPEATED ATTEMPTS TO IMPLEMENT BLOCK SCHEDULING:
There is also the reoccurring effort to do block scheduling. That matter is discussed elsewhere on this web site. I detail how having block scheduling is simply a ruse to cut time for the students and give time to the teachers for sitting around.
Since I'm no longer a teacher, I have no idea how much "conference period" time is wasted by teachers these days, but I can tell you that when I WAS a teacher, it was simply a free period to sit in the lounge.
Today academic teachers in junior highs have the same periods off so they can sit around and talk about the students. I find that practice highly offensive. Teachers don't need to talk to other teachers about their mutual students.
