Rigor-Free Research?

Forget the anecdotes and assumptions. Under the No Child Left Behind Act,
federal education dollars are supposed to fund only programs proven
effective by "scientifically based research." That's spotlighting a
problem: A lot of what passes for education research isn't reliable or
rigorous, and many education professors aren't keen on the scientific method.
Education has a "dirty little secret," writes Jeffrey Mervis in the June
11, 2004 Science Magazine:
"No program has yet met that rigorous standard, because none has been
scientifically evaluated and shown to be effective. (A related secret is
that there's no consensus on the type of evaluation studies that are needed.)"
Bush's Education Department wants controlled studies, like the tests that
determine whether a new drug is safe and effective. Is Panacea Z more
likely to cure ignorance than Brand X? It would be nice to know before
investing millions of dollars. And yet the research often provides no guidance.
In May, the National Research Council tried to determine the effectiveness
of middle-school math curricula developed by the National Science
Foundation and by commercial publishers. After identifying 698 studies of
19 curricula, NRC concluded it was impossible to decide which programs work
and which don't. While about 20 percent of studies met NRC's minimal
standards, no one program was backed by sufficient research to prove its
effectiveness.
Most of the NRC's 212-page report discussed how to evaluate education
programs in a scientifically valid way, Mervis writes. "The problem is
complicated by the many factors that influence student achievement:
students' previous knowledge, their teachers' quality of training, the
level of resources available, the degree of parental and community support,
and so on."
In July, the Education Department unveiled the new, improved What Works
Clearinghouse which reports on which educational programs, products,
practices and policies are backed by research, and evaluates the strengths
or weaknesses of the studies.
For example, the clearinghouse looked at 300 studies on peer-assisted
learning (students tutoring each other) and found 15 that met evidence
standards; 176 studies didn't pass the screen and 109 are still being
reviewed.
Of 70 studies on two middle school math curricula, only one met evidence
standards fully, another met the standards with some reservations and 20
are still being reviewed.
Controlled studies are harder to do with children than with lab rats,
especially if everyone assumes that the experimental group is getting
something special that should be available to everyone.
Evaluating some questions requires following students for many years, but
students move around so much it's hard to keep track of them. Some studies
-- for example on the effectiveness of bilingual vs. English immersion
classes -- get muddled because teachers aren't following the model they're
supposed to be using. Controlling for home factors also is challenging. If
the study is small, a few atypical students or teachers can throw off the
results, critics say. If it's large, it costs a fortune.
Some educators say there's no point in doing controlled studies: The
evidence will be ignored by policy makers. Or they complain that schools
will focus on measurable outcomes -- test scores -- and ignore what's hard
to measure.
Yet without scientific rigor, education researchers can't answer any of the
interesting questions.
"Education is often degraded by the use of pseudoscience or weak science or
anecdote in lieu of better methods," writes Grover J. (Russ) Whitehurst,
research director for the U.S. Education Department, in a Chronicle of
Higher Education story.
Academics in the American Education Research Association typically do
"qualitative" and "ethnographic" research, notes the Chronicle. Like
anthropologists, they describe what goes on in a classroom or at a school,
but don't provide any data that makes it possible to figure out whether one
approach works better than another.
"Fewer than 10 percent of AERA members are knowledgeable about randomized
trials," Robert F. Boruch, a Penn education and statistics professor, tells
the Chronicle. "And even fewer have actually worked on a randomized trial."
As a result, education professors have been frozen out of major new
studies, often in favor of private research firms like Mathematica, which
is evaluating software that claims to boost reading and math skills, and
MDRC, which has specialized in job training and welfare reform. Labor
economists, statisticians and psychologists have the skills to do
controlled studies. For the most part, the education professors do not.
Of course, some are converting to rigorous research. It's where the money
is. And plenty of academics really do want to know what works.
But there's a deep well of hostility to cold, hard, number-heavy science,
poisoned further by liberal elites' loathing of the Bush administration.
Though the move to controlled studies started in the Clinton
administration, it didn't take off till Bush pushed through No Child Left
Behind, which greatly increased federal education funding and insisted that
all federally funded programs be research-based. If Bush's guys want
scientific rigor, it must have something to do with Halliburton, right?
