Dicipline Problems in the Schools

I'm returning to the library the book "Solving Discipline Problems" by Charles Wolfgang. Excellent book. Clearly a text and since it is in its fifth edition clearly popular. In California there is no credential requirement that HS teachers take a course in "Classroom Management" (the euphemism for keeping the class under your control and not theirs). Pity, since not knowing how to control the class room is the main thing driving people out of the teaching trade. This book should be handed out to every teacher before they enter the class room.
