Hey, guys, before we get too worked up about PISA it seems to me we need to answer a more fundamental question: does PISA measure anything worth measuring?
We have discussed on this listserv the negative impacts of No Child Left Behind and its incessant focus on standardized testing. No Child emphasizes rote learning to the exclusion of the many skills that we as museum educators hold dear: innovation, art, making, creative thinking. At best, No Child tests for linguistic and mathematical skills. Howard Gardner's other intelligences are nowhere to be found.
The problems with No Child are problems with standardized testing in general. Only those skills that lend themselves to multiple choice questioning make it onto the tests. Everything else is devalued as a result. (I heard somewhere that SAT tests are very good at predicting one thing: students' later success at taking GRE tests.)
So I ask: do we really want to buy into the idea that PISA measures something important about differences in education across cultures? As we have seen with No Child, it's a slippery slope.
