In a recent post, Kevin Drum of Mother Jones discusses his growing skepticism about the research behind market-based education reform, and about the claims that supporters of these policies make. He cites a recent Los Angeles Times article, which discusses how, in 2000, the San Jose Unified School District in California instituted a so-called “high expectations” policy requiring all students to pass the courses necessary to attend state universities. The reported percentage of students passing these courses increased quickly, causing the district and many others to declare the policy a success. In 2005, Los Angeles Unified, the nation's second largest district, adopted similar requirements.
For its part, the Times performed its own analysis, and found that the San Jose pass rate was actually no higher in 2011 compared with 2000 (actually, slightly lower for some subgroups), and that the district had overstated its early results by classifying students in a misleading manner. Mr. Drum, reviewing these results, concludes: “It turns out it was all a crock."
In one sense, that's true – the district seems to have reported misleading data. On the other hand, neither San Jose Unified's original evidence (with or without the misclassification) nor the Times analysis is anywhere near sufficient for drawing conclusions - "crock"-based or otherwise - about the effects of this policy. This illustrates the deeper problem here, which is less about one “side” or the other misleading with research, but rather something much more difficult to address: Common misconceptions that impede deciphering good evidence from bad.
