I have to confess that when I see a page in a report with the text
'Why PISA isn't the whole truth
GOVERNMENT
CENSORSHIP
PROTECTING YOU FROM REALITY'
I sort of expect the next bit to be about flying saucers.
In a manner of speaking, I am not altogether wrong in the case of this particular piece. The critique that followed that page is garbled and incoherent and conspicuously lacking in references to studies of PISA by reputable researchers.
However, it seems to me that all of the bullets do in fact indicate something about the students in the individual countries, or suggest questions about what schools in different countries are doing -- for instance, why do students in the Netherlands try to answer all items even if they resort to guessing towards the end of the time period, while Greek students plod do not?
WRT the point 'Uncontrollable Variables' and the assertion that there are issues such as
'sampling, exclusions, response rates, test taking habits, culture, and language are quantitatively important.
- the subtitled TV programs, differences in genetic equipment, pre-scholar education, and extra-scholar environment'
that render the test meaningless --
Cutting through the clunky English and assuming the phrase 'genetic equipment' means inherent intelligence levels, my response to this one is - well DUH. Children come from different homes and parents can afford different levels of support for their children's education, children inherit different intellectual capacities from parents and are raised with or without certain values that enable them to succeed in school. If that is to be taken seriously as a critique of PISA, then it is equally a critique of all attempts to extract data from assessments of student progress.
The truth is out there
There are much better critiques out there.
