Middle, high schoolers stuck in science score rut

Elementary school children have made gains in science, based on the first national test in five years, but students in middle and high school have not escaped their rut.

The lackluster performance by older children underscores the deep concern among political and business leaders who see eroding science achievement as a threat to the U.S. economy.

A more hopeful sign is that young children are getting better at earth, physical and life sciences, according to test scores released yesterday. That improvement comes even as their schools tend to focus on math and reading, subjects targeted by federal education law.

The 2005 science scores are from the National Assessment of Educational Progress, a federal test given periodically on a range of topics. It is considered the best measure of how students perform over time and of how one state stacks up against another.

In a step forward on a national priority, black and Hispanic students narrowed their achievement gap with white students in fourth grade. But that good news was limited.

Racial gaps did not shrink in eighth grade, and the gap between blacks and whites even widened in 12th grade.

Overall science scores mirrored a recent pattern in other subjects: Elementary-school students improve, middle-school students do not and high-school students also stagnate or slip.

"It's perplexing," said Darvin Winick, chairman of the independent National Assessment Governing Board, which oversees the test. "Almost everybody is on the high-school reform bandwagon now, and all this report should do is fuel that fire a little more."

The 12th-grade scores have not changed since the science test was last given, in 2000. But they have dropped over a longer, 10-year testing period.

Students were challenged to understand the principles of science, to use their skills to investigate and to apply science knowledge to solve everyday problems. Topics ranged from concepts of air and space to the functions of living organisms.

The goal is for all students to show that they can handle challenging subject matter, a skill level known as proficient. In grades four and eight, fewer than one in three students -- 29 percent -- achieved at that level or better. Only 18 percent of 12th graders did that well.

The younger students, at least, are moving in the right direction.

Fourth-graders posted a better overall test score in science compared with how they performed in 2000. The lowest-performing students made the gains, lifting the overall score. Yet even in fourth grade, the percentage of students who could handle challenging work did not improve.

Most states did not improve in science in grade four or eight.

The states posting the highest number of children who could handle challenging science material include Massachusetts, Montana, New Hampshire, North Dakota, Vermont and Virginia.

Among states with the lowest percentages of children doing proficient work are Alabama, Arizona, California, Hawaii, Louisiana, New Mexico, Nevada and Mississippi.
