Educators challenges science-test ratings

WASHINGTON -- A widely publicized test that showed U.S. 12th-graders trailing other countries in math and science was based on flawed methods that distorted the results, an education professor contended Thursday in a scientific journal. Iris C. Rotberg, research professor of education at George Washington University, said the Third International Mathematics and Science Study "tells us little about the quality of education" in the United States or other countries. The critique appeared in Science, the journal of the American Association for the Advancement of Science.
