Study Concludes Teacher Professional Development Programs Are Expensive But Ineffective.

Jay Mathews writes in the Washington Post (9/14, Mathews) about “a new study delving deep into the uselessness of professional development” for teachers. Researchers found in their “survey of teachers that ‘only about 40 percent reported that most of their professional-development activities were a good use of their time.’” Still, the 50 largest US school districts “spend at least $8 billion a year on these often-ineffective teacher-training activities.”
