Yes, it’s that time again, when the OECD releases the PISA test results and Education Ministers everywhere frantically start to spin the information to justify whatever plans they already had. Statisticians in government departments everywhere lurch across desks in darkened rooms, poring over the data, eagerly cherry picking the bits that serve their Minister’s purpose. Such fun!
Then there are those dedicated researchers who put out articles quick-smart explaining why PISA is flawed and unreliable. They explain in great detail the ins and outs of data collection and test setting and statistical analysis and, despite our best efforts, maybe one in a thousand of us can follow what they are saying. But we read anyway and nod sagely. Because there are graphs and there is data, so it must be good stuff.
The media, of course, enter into some kind of Nirvana, gleefully whipping up a hoohah about countries “slipping down” or “surging up” the tables. Heaven forbid a country has the temerity to stay in the same place – how’s a journo meant to get a headline out of that kind of carry on?
Of course, in all of this madness, we could take the Yong Zhao route and denounce PISA altogether – say no to the sausage factory. But that doesn’t sell papers or make for rousing Ministerial pronouncements, or even attract blog readers, so, yeah nah.
Instead, yet again, we will be treated to the PISA circus, like it or not, so please remember to engage your critical thinking skills.
