There are ton of issues that affect Teacher time on task
-Announcements
-Crappy playgrounds that leave kids to just beat on each other (You laugh but this was a problem at Thomson)
-Same issue but kids don't know how to play and teachers have to deal with all the conflicts
-Kids whose parents have spent the morning berating them and they are a mess- we have all seen it.
-Parents wanting just a few minutes with the teacher, yes even I have done it and don't you dare ask me to leave
-Chronically late kids (see the thread with the 4th grader that can't make it class before 9:00 am
-Poorly designed classrooms that make getting on task more difficult (see those lovely open school buildings)
-teachers who just don't know how to do it, harder than most of us realize.
Like many things on task makes sense but wow it is amazing how hard it can be to implement.
