I am floored by this. I'm not even sure what my reaction is yet.
How does this relate to testing?? We spend so much time testing our kids to find out what they "know." Forget all the research. Forget all the teachers, students and parents crying out that testing is not a measure of how good their school is.
This one simple quiz brilliantly shows that kids are learning.
How much of our testing is misrepresented simply by the context in which the questions were asked?
