ARTICLE: A Ravitch Review

The Myth of Charter Schools

"Some fact-checking is in order, and the place to start is with the film’s quiet acknowledgment that only one in five charter schools is able to get the “amazing results” that it celebrates. Nothing more is said about this astonishing statistic. It is drawn from a national study of charter schools by Stanford economist Margaret Raymond (the wife of Hanushek). Known as the CREDO study, it evaluated student progress on math tests in half the nation’s five thousand charter schools and concluded that 17 percent were superior to a matched traditional public school; 37 percent were worse than the public school; and the remaining 46 percent had academic gains no different from that of a similar public school. The proportion of charters that get amazing results is far smaller than 17 percent.Why did Davis Guggenheim pay no attention to the charter schools that are run by incompetent leaders or corporations mainly concerned to make money? Why propound to an unknowing public the myth that charter schools are the answer to our educational woes, when the filmmaker knows that there are twice as many failing charters as there are successful ones? Why not give an honest accounting?"

"Guggenheim seems to believe that teachers alone can overcome the effects of student poverty, even though there are countless studies that demonstrate the link between income and test scores. He shows us footage of the pilot Chuck Yeager breaking the sound barrier, to the amazement of people who said it couldn’t be done. Since Yeager broke the sound barrier, we should be prepared to believe that able teachers are all it takes to overcome the disadvantages of poverty, homelessness, joblessness, poor nutrition, absent parents, etc."

"Hanushek has released studies showing that teacher quality accounts for about 7.5–10 percent of student test score gains. Several other high-quality analyses echo this finding, and while estimates vary a bit, there is a relative consensus: teachers statistically account for around 10–20 percent of achievement outcomes. Teachers are the most important factor within schools... But the same body of research shows that nonschool factors matter even more than teachers. According to University of Washington economist Dan Goldhaber, about 60 percent of achievement is explained by nonschool factors, such as family income."

"The film never acknowledges that charter schools were created mainly at the instigation of Albert Shanker, the president of the American Federation of Teachers from 1974 to 1997. Shanker had the idea in 1988 that a group of public school teachers would ask their colleagues for permission to create a small school that would focus on the neediest students, those who had dropped out and those who were disengaged from school and likely to drop out. He sold the idea as a way to open schools that would collaborate with public schools and help motivate disengaged students. In 1993, Shanker turned against the charter school idea when he realized that for-profit organizations saw it as a business opportunity and were advancing an agenda of school privatization."

"While blasting the teachers’ unions, he points to Finland as a nation whose educational system the US should emulate, not bothering to explain that it has a completely unionized teaching force. His documentary showers praise on testing and accountability, yet he does not acknowledge that Finland seldom tests its students. Any Finnish educator will say that Finland improved its public education system not by privatizing its schools or constantly testing its students, but by investing in the preparation, support, and retention of excellent teachers. It achieved its present eminence not by systematically firing 5–10 percent of its teachers, but by patiently building for the future. Finland has a national curriculum, which is not restricted to the basic skills of reading and math, but includes the arts, sciences, history, foreign languages, and other subjects that are essential to a good, rounded education. Finland also strengthened its social welfare programs for children and families"

Dr. Ravitch has much more to say. It's a meaningful article. If you haven't read The Death and Life of the Great American School System, I strongly recommend it.
