Of course teachers should do planning. Nobody would dispute that.
But LoPresti seems to think teachers simply cannot get it together to do planning unless there is time set aside during the school day for them to do it, and of course, according to LoPresti, there must be money set aside to pay them for the time they spend to make their plans.
Teachers are supposed to be professionals. That means they take the time to make their lesson plans while they are sitting monitoring a study hall, or while they are at home. For 30 years I was a professor and a public school teacher; and I did a LOT of research and planning; but I would never have expected to have paid time during the school day to plan my lessons, grade my students' papers, etc.
Kwitcherbellyachin and start acting like a professional.
