BENTON HARBOR — The idea that failing schools can be rapidly turned around is a myth, say two Michigan professors.

“School turn-around means that you have someone come in and they change some things and test scores dramatically improve,” said Tom Pedroni, an associate professor at Wayne State University, who specializes in researching urban school districts where the students are mostly poor and of color. “Most cases where that has been claimed, those claims have been debunked in a couple of years.”
