There is a strongly-held myth many academics, policymakers, and reformers repeat weekly: schools hardly ever change. Those who believe in this myth often cite the large literature demonstrating failed innovations in schools or point at calcified bureaucracies and stubborn teachers and principals who block reform after reform (see here and here). Like all myths, this one has a factual basis. There have been many failures to transform schooling in the U.S. From open-space schools to vouchers, there have indeed been vain attempts to alter the course of schooling.
Such a myth is useful for those who beat the drums that U.S. schools are broken. After all, they seek changes that meet their view of what constitutes a “good” education. “Troubled” schools is the basis for the profound pessimism that presently exists over the capacity of public schools to improve. So it is a politically useful myth, but it is inherently mistaken nonetheless.
