How are the examples you gave examples of cultural bias? Sounds more like “household” bias, which will change from home to home.
[/QUOTE]
How many households = a culture? Every single person I interact with (or more importantly, my daughter interacts with) on a regular basis calls animal cookies “cookies” and granola bars “candy”.
But anyway, I think you’re missing the point for the detail.
The point: the test is designed to measure language skills.
The detail: the test in fact measures vocabulary, a small subset of language skills.
The other test is designed to measure the child’s ability to follow verbal directions. Again, it in fact is useless without vocabulary.
Vocabulary is highly dependent on culture.
This wouldn’t be so bad if the tests were marked and labeled as being vocabulary tests, since that is part of what they test. But these are marketed, scored and paid for by the state as being unbiased language ability tests, suitable for children of any background. Obviously, they’re not.
Without looking at the tags, what would you reach for if I asked you to “give the baby natto”? One two or three? Would your (presumed) ignorance of natto be a good reason for me to believe you don’t have the cognitive ability to follow directions?
Obviously, these examples are not identical to the suspected bias on standardized tests for adults. I presented them as simple, easy to grok examples of how a test can be rendered invalid because what it claims to be testing for isn’t all it tests for. Certainly, I agree that a teacher teaching in a diverse school environment should indeed be able to pass a test that is itself diverse. I’m not trying to argue against the OP, because I actually agree.
