Myth #1 - Teachers are the most important factor in student achievement.
The movie asserts a central thesis in today’s school reform discussion: the idea that teachers are the most important factor determining student achievement. But this proposition is false. 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.Let's not ignore the film's blaming of unions for the condition of the public schools...while ignoring the fact that states without collective bargaining laws for teachers have among the lowest achieving students (based on test scores) in the country.*(Click here for more)
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. So while teachers are the most important factor within schools, their effects pale in comparison with those of students’ backgrounds, families, and other factors beyond the control of schools and teachers. Teachers can have a profound effect on students, but it would be foolish to believe that teachers alone can undo the damage caused by poverty and its associated burdens.
Myth #2 - Charter schools will solve all our problems.
The film raises Charter schools as the answer to the problems of our "failing" public schools, but Guggenheim failed to mention two things. First...most charter schools are NOT doing any better than public schools...
...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?...and second, that the successful charter school highlighted in the film has resources that no public school has...
Guggenheim didn’t bother to take a close look at the heroes of his documentary. Geoffrey Canada is justly celebrated for the creation of the Harlem Children’s Zone, which not only runs two charter schools but surrounds children and their families with a broad array of social and medical services. Canada has a board of wealthy philanthropists and a very successful fund-raising apparatus. With assets of more than $200 million, his organization has no shortage of funds. Canada himself is currently paid $400,000 annually. For Guggenheim to praise Canada while also claiming that public schools don’t need any more money is bizarre. Canada’s charter schools get better results than nearby public schools serving impoverished students. If all inner-city schools had the same resources as his, they might get the same good results.Myth #3 - American Public Schools are a failure.
But contrary to the myth that Guggenheim propounds about “amazing results,” even Geoffrey Canada’s schools have many students who are not proficient. On the 2010 state tests, 60 percent of the fourth-grade students in one of his charter schools were not proficient in reading, nor were 50 percent in the other. It should be noted—and Guggenheim didn’t note it—that Canada kicked out his entire first class of middle school students when they didn’t get good enough test scores to satisfy his board of trustees. This sad event was documented by Paul Tough in his laudatory account of Canada’s Har- lem Children’s Zone, Whatever It Takes (2009). Contrary to Guggenheim’s mythology, even the best-funded charters, with the finest services, can’t completely negate the effects of poverty.
Most Americans graduated from public schools, and most went from school to college or the workplace without thinking that their school had limited their life chances. There was a time—which now seems distant—when most people assumed that students’ performance in school was largely determined by their own efforts and by the circumstances and support of their family, not by their teachers. There were good teachers and mediocre teachers, even bad teachers, but in the end, most public schools offered ample opportunity for education to those willing to pursue it. The annual Gallup poll about education shows that Americans are overwhelmingly dissatisfied with the quality of the nation’s schools, but 77 percent of public school parents award their own child’s public school a grade of A or B, the highest level of approval since the question was first asked in 1985.The film misleads viewers and misrepresents the American Public School system.
Perhaps the greatest distortion in this film is its misrepresentation of data about student academic performance. The film claims that 70 percent of eighth-grade students cannot read at grade level. This is flatly wrong. Guggenheim here relies on numbers drawn from the federally sponsored National Assessment of Educational Progress (NAEP). I served as a member of the governing board for the national tests for seven years, and I know how misleading Guggenheim’s figures are. NAEP doesn’t measure performance in terms of grade-level achievement. The highest level of performance, “advanced,” is equivalent to an A+, representing the highest possible academic performance. The next level, “proficient,” is equivalent to an A or a very strong B. The next level is “basic,” which probably translates into a C grade. The film assumes that any student below proficient is “below grade level.” But it would be far more fitting to worry about students who are “below basic,” who are 25 percent of the national sample, not 70 percent.Ravitch's review blows holes through Waiting for Superman. Will the president, secretary of education, state departments of education, millionaire "reformers" and the public listen? Probably not. At the end of the day we'll have the pro-charter, pro-testing, anti-union, anti-public education folks go on their merry way and continue to distort what's happening to public education in America while the charters continue to line the pockets of the rich and the rich continue to deny the effects of poverty.
Hey Dad, Can I post a link to this on my Facebook? It's really interesting and I'd like for some of my friends to see it.
