National science test shows only slight improvement - The Washington Post: National tests measuring science knowledge among eighth-graders show slight improvement compared with those of two years earlier,but one-third of all students still lack a basic understanding of the physical, life and earth sciences, according to a federal study made public Thursday.

The tests showed that black and Hispanic students had made slightly more progress than white students, making a tiny dent in the persistent achievement gaps between the racial groups.
