Science Ability Drops In U.S. High Schools
The first science test administered in five years across the United States shows that achievement among high school seniors has declined across the past decade, even as scores in science rose among fourth-graders and held steady among eighth-graders, the U.S. Department of Education has reported.

The falling average science test scores among high school students, announced Wednesday, appeared certain to increase anxiety about American academic competitiveness and to add new urgency to calls from President George W. Bush, governors and philanthropists like Bill Gates for an overhaul of American high schools.

The drop in science proficiency appeared to reflect a broader trend in which some academic gains made in elementary grades and middle school have been seen to fade during the high school years. The science results come from the National Assessment of Educational Progress, a comprehensive examination administered in early 2005 by the Department of Education to more than 300,000 students in all 50 states, the District of Columbia, and on U.S. military bases around the world.

"Our fourth-graders are doing better - that's the good news," said Darvin Winick, chairman of the bipartisan body set up by Congress to oversee the test. "But the 12th-grade results are distressing, there's no other way to slice it."

The science test, which was administered during the first months of 2005, covered the earth, physical and life sciences, and was last given in 2000 and in 1996. The test administrators translate scores into three achievement levels: advanced, proficient and basic.

On the most recent test, 68 percent of fourth-graders achieved at or above the basic level, compared to 63 percent on the 2000 and 1996 tests.

The rising science achievement among fourth graders mirrored similar trends on nationwide reading and math tests released last fall. In interviews, analysts attributed those increases to the broad movements for higher standards and accountability that began in most states during the 1990s and gained force when Bush signed the No Child Left Behind law in 2002.

Eighth-grade scores were largely unchanged from 10 years ago, with 59 percent of students scoring at or above the basic level in 2005, while 60 percent of students were at or above basic in 1996. Officials called those results disappointing, but the results from secondary schools were worse.

Among high school seniors, 54 percent performed at or above the basic level in science in 2005, compared to 57 percent in 1996. Eighteen percent of high school students performed at the proficient level in 2005, down from 21 percent in 1996.

To achieve at the basic level on the National Assessment, high school seniors must demonstrate knowledge of very basic concepts about the earth, physical and life sciences, and show a rudimentary understanding of scientific principles.

There was some debate about how to explain the 12th-grade declines. Assistant Secretary of Education Tom Luce said they reflected a national shortage of fully qualified science teachers, especially in poor regions, where physics and chemistry classes are often taught by teachers untrained in those subjects.

"We lack enough teachers with content knowledge in math and science," Luce said. "We have too few teachers with majors or minors in math and science. That clearly is a problem."

Michael Padilla, a professor at the University of Georgia who is president of the National Science Teachers Association, said that the problem is not that universities are failing to train sufficient numbers of science majors or that too few opt for classroom careers, but that about a third of those who accept teaching jobs abandon the profession within five years.

"What happens is that the system tends to beat them down," Padilla said. "Working conditions are poor, it's a difficult job, and the pay isn't that great."
