R&D That Makes a Difference

Robert E. Slavin | Posted 08.27.2015 | Education

Over the course of my career, I've written a lot of proposals. I've also reviewed a lot, and mostly, I've seen many funded projects crash and burn, or produce a scholarly article or two that are never heard of again.

Healing and Human Touch

Early this summer, I spent several days in a hospital bed, tethered to an IV, with what proved in retrospect to be anaplasmosis (a nasty bit of tick-b...

I Was Wrongfully Convicted And So Are Too Many Others

Lorenzo Johnson | Posted 08.25.2015 | Crime
Lorenzo Johnson

Many innocent people are sitting in prison with convictions for crimes they did not commit. This is often due to prosecutors who blatantly ignore information that might point away from their chosen suspect. Much of the time, these other leads could have exonerated an innocent prisoner, but they go totally disregarded.

What Counts as Research?

We can respectfully disagree about strategies and methodologies, of course, but a broader interest in the findings of educational research within the policy community seems sure to be beneficial to the research community.

Who Opposes Evidence-Based Reform?

Robert E. Slavin | Posted 08.13.2015 | Education
Robert E. Slavin

Many teachers are uneasy about evidence, because they see it as one more way they may be oppressed by standardized tests, or that they may be forced to implement proven programs. I'm sympathetic to teachers' concerns in these arenas, but policies to allay these concerns are possible.

Lighthouses

Robert E. Slavin | Posted 07.30.2015 | Education
Robert E. Slavin

Lighthouses once guided ships to safe harbors, but in education, policies limited to finding and celebrating lighthouse schools are less likely to improve outcomes more broadly. They may lead policy in a good direction, but they may just as likely guide us onto the rocks.

Zeal, Veal and Veganism

David Katz, M.D. | Posted 07.20.2015 | Healthy Living
David Katz, M.D.

When my vegan friends and colleagues say that a vegan diet is categorically the best for human health, it is an excess of zeal. We simply do not have ...

To Pluto and Beyond

Robert E. Slavin

We are a hugely wealthy country, and we can afford to go to Pluto and to educate our children to a much higher standard than we do. In fact, the way we became a hugely wealthy country, and the only way we can maintain our wealth into the future, is by investing in education, science, technology and invention.

Good Failure/Bad Failure

Robert E. Slavin | Posted 07.09.2015 | Education
Robert E. Slavin

Evidence junkies (like me) are reacting to the disappointing news on the evaluation of the Adolescent Behavioral Learning Experience (ABLE), a program implemented at Rikers Island to reduce recidivism among adolescent prisoners. Bottom line: The rigorous independent evaluation of the program failed to find any benefits.

Wisconsin Lawmakers Continue to Practice Legislative Malpractice

Sara Finger | Posted 07.08.2015 | Politics
Sara Finger

I've personally witnessed dozens of doctors speak with legislators to explain that the medical evidence doesn't support the arguments for restricting abortion at 20 weeks, or that the life and health of Wisconsin women will be threatened by bills like Senate Bill 179.

Innovation Nation

Robert E. Slavin | Posted 07.02.2015 | Education
Robert E. Slavin

As we celebrate our nation's birthday, I thought I'd once again remind those few of you who, instead of having picnics, are reading blogs, how the U.S. came to be, and how innovation has been baked into its DNA since Day 1.

Happy 50th Birthday, Head Start!

Robert E. Slavin | Posted 05.21.2015 | Education
Robert E. Slavin

Of all the Great Society programs, Head Start is perhaps the most popular. It provides center-based services to millions of very cute 3- and 4-year-olds, mostly children from disadvantaged families. If members of the public, educators, and policy makers know a single conclusion from educational research, it is that early-childhood programs have long-term positive impacts.

Sobering Lessons From the Lone Juror in the Etan Patz Case

Dan Simon | Posted 05.15.2015 | Crime
Dan Simon

The Hernandez case confirms the adage that "confession is the queen of evidence." Even without a shred of physical evidence, an almost unanimous jury voted for conviction based on a 33-year-old statement, given by a man suffering from a personality disorder and limited intelligence.

Building on Today's Progress for 2016 and Beyond

Michele Jolin

We know more than ever before about what works to improve results for young people, their families and communities, and across the country there is growing bipartisan momentum behind shifting public funds toward evidence-based solutions.

Accountability and Evidence

Robert E. Slavin | Posted 05.26.2015 | Education
Robert E. Slavin

The way we can find out what works is to compare schools or classrooms assigned to use any given program with those that continue current practices. Ideally, schools and classrooms are assigned at random to experimental or control groups. That's how we find out what works in medicine, agriculture, technology, and other areas.

Pi and Science, Sense and Cake

David Katz, M.D. | Posted 05.17.2015 | Healthy Living
David Katz, M.D.

When the beverage industry, for instance, helpfully points out that no long-term, randomized trial has specifically implicated their sugary concoction in epidemic childhood obesity, we might consider that no such trial has ever implicated any given snowflake in an avalanche fatality, either. Perhaps avalanches are actually innocuous.

Social Spending Innovation Research

Robert E. Slavin | Posted 04.28.2015 | Education
Robert E. Slavin

From its earliest days, innovation has been the lifeblood of the American economy. When Americans face problems, they innovate to find solutions. Innovation is how America solves problems. We need to find every way we can to help innovators solve the serious problems we face in education.

We're Fat And Sick And The Broccoli Did It!

David Katz, M.D. | Posted 04.26.2015 | Healthy Living
David Katz, M.D.

It's no big surprise that someone untrained in research methods would tell us all what the research really means and why the scientists on this committee -- all trained to do research and interpret it -- are just a bunch of hacks. But that the New York Times would allocate its imprimatur and rarefied real estate to an infomercial masquerading as an Op-Ed is a lamentably disappointing surprise.

Paleo for a Shrinking Planet?

David Katz, M.D. | Posted 04.21.2015 | Healthy Living
David Katz, M.D.

While many do, no one can say that a Paleo diet is best for health on the basis of truly robust evidence. But no one can say it isn't, either.

Cholesterol, Unscrambled

David Katz, M.D.

Whether adding eggs to your diet will confer benefit, harm, or neither, almost certainly depends on what you are now eating instead of eggs, and what eggs would be displacing.
