Over at a newly discovered blog I found this:
Did you hear about the big report that came out this week? You know, the one that "shows" that NYC charter schools are better than traditional non-charter public schools? It has gotten a ton of attention, probably because it uses "'the gold standard' method[ology]." The report is not subtle about this. It is right there in the very first sentence of the executive summary, "The distinctive feature of this study is that charter schools' effects on achievement are estimated by the best available, "gold standard" method: lotteries." It even uses the term "gold standard" four more times throughout the report.Everyone wants to follow The Gold Standard -- or at least be able to say that they do. Of course! I mean, who wouldn't? But I do not think that we actually have a gold standard in education research. In fact, I am quite sure that we do not, and appropriating biomedical research's gold standard does not make it appropriate for us.However, if we are going to borrow their standard, can we not at least get it right?The biomedical standard uses double-blind experimental studies with random assignment. That means that some research participants get the experimental treatment and some get a placebo, and both are assigned randomly. It also means that neither the researchers nor the participants know who is getting which treatment. After all, expectations are important, and the mind can set us up for all kinds of things.
You should go read the rest, as it pretty much demolishes the research, as well as education research itself! Oh, and there are problems with education research aplenty.
