U.S. Students improve in math but not science on the TIMMS

This report from the National Center for Education Statistics within the Institute of Education Sciences summarizes the performance of U.S. fourth- and eighth-grade students on the 2007 Trends in International Mathematics and Science Study (TIMSS), comparing their scores with their peers internationally as well as documenting changes in mathematics and science achievement since 1995. The report also describes additional details about trends in the achievement of students within the United States, by sex, racial/ethnic background, and the poverty level of the schools they attend....
TIMSS has been administered four times: in 1995, 1999, 2003, and 2007. The United States participated in all four administrations. In 2007, 36 countries participated at grade four, while 48 participated at grade eight.

Mathematics

Results show that the 2007 average mathematics scores of both U.S. fourth- and eighth-grade students were higher than the TIMSS scale average. At grade four, the average U.S. mathematics score was higher than those in 23 of the 35 other countries, lower than those in 8 countries (all 8 were in Asia or Europe), and not measurably different from those in 4 countries. At grade eight, the average U.S. mathematics score was higher than those in 37 of the 47 other countries, lower than those in 5 countries (all located in Asia), and not measurably different from those in 5 countries.

Comparing average scores from the first administration of TIMSS in 1995 to the most recent results from 2007 showed that both U.S. fourth- and eighth-graders improved in mathematics.

Science

In science, the average scores of both U.S. fourth- and eighth-graders were higher than the TIMSS scale average. At grade four, the average U.S. science score was higher than those in 25 of the 35 other countries, lower than those in 4 countries (all of them in Asia), and not measurably different from those in 6 countries. At eighth grade, the average U.S. science score was higher than the average scores in 35 of the 47 other countries, lower than those in 9 countries (all located in Asia or Europe), and not measurably different from those in 3 countries.

Unlike in mathematics, the average science scores for both U.S. fourth- and eighth-grade students were not measurably different in 2007 compared to the first TIMSS results collected in 1995.
