“I contend that their solutions are not working. Some are demonstrably wrong. Some, like charter schools, have potential if the profit motive were removed, and if the concept were redesigned to meet the needs of the communities served rather than the plans of entrepreneurs. It is far better to stop and think than to plunge ahead vigorously, doing what is not only ineffective but wrong. We must always be open to trying new ideas in the schools, but we should try them first on a small scale and gather evidence before applying and mandating new ideas nationwide. When evidence is lacking, we should not move forward with a sense of urgency.” (Diane Ravitch, Reign of Error)
