How about those "best practices"?

I maintain that "best practice" consists of whatever will get the point across to a particular group of kids. That may change from class period to class period, depending on the kids' needs, never mind year to year.

Here's what Larry Cuban has to say on the subject:

Where does phrase “best practices” originate? Its origin seems to be in the business sector with management consultants. It has become a buzzword across governmental, educational, and medical organizations. In becoming popular, the phrase has drifted away linguistically from its original meaning of effective practices in accomplishing goals to mean faddish or trendy activities.

Pay attention to what he says about medical research and one-size-fits-all procedures.

He goes on to say:  ...I am not the first educator, nor the last, to make the point that school reform is a value-driven (not research-driven) business where policymakers depend far more on faith than facts and far more on uniformity than context.
In comparing “best practices” in medicine and education, I now see more clearly how (and why) state and federal policymakers, grasping for anything that looks like success, spread faddish and unexamined reforms. This is both a sham and a shame.
