Center Funding Research on Math, Science Cognition
Four years ago, federal officials launched an initiative to study the complex machinery of mathematics and science cognition, or in plain language, how students think, learn, and solve problems in those subjects.
Since then, that program has begun to exert its influence through the relatively modest but steady flow of public funding it provides for scholarly research, work that goes largely ignored by the public at large—and even most educators—but which, over time, can have broad influence in the classroom.
The federal center goes by the lengthy title of the Program on Mathematics and Science Cognition and Learning, Development and Disorders. It operates within the National Institute of Child Health and Human Development, the same federal entity that has generated much of the research that strongly influences federal reading policy today.
By federal standards, the math and science program has a small budget: It currently underwrites about 20 ongoing projects at an annual cost of some $7 million. But it is conducting its work at a time when federal officials, including the Bush administration, are calling for greater emphasis on research-based strategies in math instruction.
A 4-year-old federal program on math and science cognition and learning has helped support studies on a range of topics including:
• Arithmetic-fact mastery in young children
• Sex differences in math and spatial skills among primary school children
• Gene research and mathematical understanding in twins
• Origins of number sense in infants
• Math and learning disabilities
• Math learning among girls with genetic syndromes and mental retardation
• "Folk science"children's understanding of the world around them
• Reasoning about design and purpose in nature among children
The central role of the NICHD program is to finance that research with public money—rather than generate it independently. Those studies, in turn, often end up in articles published in scholarly journals, which can shape the collective thinking of the education community.
“It takes a while to have an impact,” said Daniel B. Berch, the director of the program. “You have to begin to make it evident to researchers in the field that [we] support this kind of work.”
Even so, over the past few years the math- and science-cognition program’s grantees, many of whom also receive support from other federal agencies, have published about 50 articles in various journals, he estimates. One of the most widely circulated pieces was a 2004 paper that identified the potential benefits of “direct instruction,” or more straightforward presentation of facts from teachers to students, on students’ scientific reasoning and judgment. That study, whose primary author was David Klahr, a psychology professor at Carnegie Mellon University in Pittsburgh, compared that teaching approach with “discovery learning,” a more hands-on classroom method. ("NCLB Could Alter Science Teaching," Nov. 10, 2004.)
Other studies backed by the NICHD math and science program have probed such disparate topics as how students with various disabilities learn math; whether gender differences affect student learning; and how children develop math skills such as estimation, number sense, and mastery of basic arithmetic facts.
Building a Base
Some of those topics touch long-standing debates about how math and science should be taught. But Mr. Berch says while his program’s work could eventually influence classroom instruction, its impact is indirect: Those decisions are ultimately left to school officials and policymakers, he says.
“You don’t [craft] a curriculum out of one study,” Mr. Berch said in an interview from his office in a National Institutes of Health building in Rockville, Md., in suburban Washington. His program is trying to promote sustained research rather than one-shot examinations of how students learn. “We want to make it more cumulative,” Mr. Berch said.
To that end, most of the projects supported by the NICHD program are being conducted over a three- to five-year period. Most grant recipients receive between $250,000 and $500,000 in direct funding, plus additional costs, on average, he estimates.
Mr. Berch said he was asked by G. Reid Lyon, the influential and controversial former chief of the NICHD’s child-health and -behavior branch, to lead the math- and science-cognition program. The reading research supported by the NICHD has had a strong influence on the types of instruction in that subject that the federal government supports, most notably through the $1 billion-a-year Reading First grant program, which requires the use of research-based instructional strategies in that subject.
Critics have accused the NICHD of favoring research that supports phonics, a teaching method rooted in associations between sounds and letters, at the expense of other approaches.
Similar philosophical divides exist over how to teach math. The “math wars” have pitted those who call for stronger teaching of basic number facts and foundational skills against those who worry that such an approach will result in too much rote memorization and drill, and not enough problem-solving.
Over the past year, improving math and science education has become a major focus among federal officials, who worry that the nation is not turning out enough students who can fill highly skilled jobs.
Earlier this year, the Bush administration announced a series of steps aimed at improving how math is taught, including the formation of the National Mathematics Advisory Panel, a group of 17 experts charged with identifying what research says about how to teach that subject.
The NICHD program would seem well positioned to provide that research. Mr. Berch serves as one of the panel’s six nonvoting members. And two cognitive psychologists whose work has been funded through his program—David C. Geary of the University of Missouri-Columbia, and Robert S. Siegler of Carnegie Mellon University—were also named to the panel. Mr. Berch said he offered advice to Department of Education officials about who might serve, but had no say in the final selection.
Area of Need?
Mr. Geary believes the math panel can help make educators aware of the research emerging from the NICHD program. NICHD support for reading “really clarified where instruction should be focused,” Mr. Geary said, by examining “the processes of reading. I think the same applies to math and science.”
Jere Confrey, a professor of mathematics education at Washington University in St. Louis, agreed that knowing more about students’ cognitive skills in math and science is important. But she also saw a more urgent need for studies on instruction in those subjects, and how to prepare teachers to work with students of different abilities. Ms. Confrey led a panel of the congressionally chartered National Research Council that produced a report in 2004 on how to judge the effectiveness of math curricula. ("NRC Urges Multiple Studies For Math Curricula," May 26, 2004.)
“We have more problems in instruction than pure cognitive research,” Ms. Confrey said. “Cognition has to be fostered by effective and rich classroom discussion.”
Like Ms. Confrey, James Hiebert, a professor of education at the University of Delaware in Newark, questioned whether the NICHD math and science program would favor research on basic math skills rather than problem-solving ability.
“It’s easier to investigate cognition in simple-skill learning than in conceptual understanding,” Mr. Hiebert said. “Sometimes research tends to be skewed toward basic fact learning.”
But after hearing a description of various math projects supported by the NICHD program, in distinct areas such as estimation, number sense, and mastery of arithmetic facts, Mr. Hiebert added that he could detect no ideological bias in the program’s work.
Mr. Berch said his only concern is funding useful research on cognition and learning disabilities, not weighing in on ideological disputes.
“We are not taking sides with respect to the math wars,” he maintained.
In the 1970s and 1980s, cognitive research on how students solve arithmetic proved extremely valuable and shaped classroom pedagogy and curricula for years to come, Mr. Hiebert said. Today’s research could prove similarly important, he said.
“One of the problems we have in math is we don’t understand the learning processes well enough to know [which] instructional strategies might be preferred,” Mr. Hiebert said. Valuable research “eventually finds its way into the system, even if the effect is so indirect that it’s hard to trace it back to the original source.”
