I plead ignorance on some of this, but in the early 1900s through the 1960s, classroom management did not dominate a teacher's priorities. Today, cm takes up a great amount of my time. When did this happen and why? Spending my time thinking of how I will deal w/problem students and maximize everyone's potential simultaneously (yeah, right) has become an end for me and not a means toward good education. I talked to a few friends who teach at a private school, and they said cm was a non-issue for them. They actually get to teach without taking away recess, giving warnings, calling parents et al.
