 From: Ruth Parker <ruthp@pacificrim.net> snip Normreferenced standardized tests, however, guarantee that there will always be fully half of our students and roughly half of our schools at or below the 50th percentile and thus considered inadequate.
Now that is simply not true. Nothing guarantees that the school averages will be statistically distinguishable. It might happen that the school averages read like 50.001, 49.998, 50.02, ....... when the underlying individual scores have large standard deviations. Then only the averages for very large schools would be statistically significant. There is no guarantee of that half of the schools will be considered inadequate. If it turns out that some school averages are 4 standard deviations apart, well then they are.
Now let's turn to the question of half of the students being considered inadequate. When I was at MIT, I tried to take music appreciation. I spent countless hours in the library listening to Wachet Auf (Johann Sebastian Bach, Cantata No. 140). I never got it. I the choice of an F or dropping the course. I dropped. I never have felt that I was inadequate because of that. Just different. In Jr. HS, I couldn't throw the softball OR run the mile OR high jump OR chin up OR..... for a grade better than D. I did feel a bit inadequate over that. I SHOULD have been content with 'different'. Feelings of inadequacy have more to do with social attitudes than the reality of differential abilities. The differential abilities will still exist even if you don't test for them. In many schools, the differential ability gap will grow large simply because people will deny that they exist if the data don't hit them up side of the head.
RP: Highstakes normreferenced testing is detrimental to education and children as teachers experience increased pressures to just teach to the test. The multibillion dollar textbook/testing industry is driving educational policy in this country to the detriment of mathematics education. snip
The teachers should teach beyond the test rather than to it. Tests and standards are minimal criteria not end goals.
