Innovation Nation

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

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

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.

The Council of Directors of the True Health Coalition is already, only weeks after its formation, home to nearly 150 leading experts from nearly 20 countries, rallying around the same basic principles of healthy eating.

Building on Today's Progress for 2016 and Beyond

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

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

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

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

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

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.

Investing in Innovation: Informing Local Control

Robert E. Slavin | Posted 04.14.2015 | Education
Robert E. Slavin

The new Congress is working on alternative versions of the Elementary and Secondary Education Act. Republican proposals have a strong emphasis on getting the federal government out of what they believe should be local decisions. Unfortunately, the Republican bill in the House of Representatives takes out a critical support for local control: Investing in Innovation (i3).

Fund What Works!

President Obama's recently released budget may or may not make its way into law, but it has already made its way into the hearts of those who believe that government programs must be held to account for producing the outcomes they are intended to produce. Red or blue, everyone should want government dollars to make a difference.

Are Your Computer Business Records Admissible Evidence at Trial?

While the precise requirements may vary somewhat from jurisdiction to jurisdiction, it is noteworthy that businesses and their legal counsel should not take for granted the admissibly in evidence at trial of business records.

Holism, Holes and Poles

David Katz, M.D. | Posted 03.30.2015 | Healthy Living
David Katz, M.D.

The trouble with holistic medicine, or integrative medicine, is less the holes that can be poked in it by self-proclaimed sentinels of evidence, and more our prevailing tendency to gravitate to diametric poles. The best way forward is the road less traveled, which lies, as it often does, in the middle.

To Achieve Big Results From Social Policy, Add This

Lisbeth (Lee) Schorr | Posted 03.23.2015 | Politics
Lisbeth (Lee) Schorr

The growing chasm between unmet social needs and what our social institutions are routinely accomplishing cannot be crossed one small step, or one standardized program, at a time. Something shown to have worked somewhere will not automatically produce the same effects elsewhere.

Examining The Annual Exam

David Katz, M.D.

In last week's New York Times, Dr. Ezekiel Emanuel suggested that this year's resolution might be to abandon the ritual of your annual physical. The title of his column, perhaps chosen by an editor to maximize glibness and thus provocation was: "Skip your annual physical." But permit me to suggest you don't commit to that just yet. The annual physical exam warrants some more examination, a defense to follow its prosecution.

Collect the Learning Evidence

Good educators know that evidence gathering is a central component of their craft. Perhaps they don't use the term "evidence" to describe what they search for, preferring instead "testing" or other assessment-related jargon.

Why The Whole Family Benefits When Kids Believe In Santa

Children are empowered by feeling that they have figured it out by themselves. Upon making the discovery, they become part of the adult world; they are "in on the secret" and can derive even more emotional benefit by being given a role in keeping the myth alive for their younger siblings.

Getting the Facts Right About the Ferguson Grand Jury Decision

As we discuss and debate the grand jury's decision not to indict Darren Wilson, we'll inevitably have differences of opinion -- some slight; some extreme. But we owe it to one another to ensure that our opinions are founded on a correct understanding of the underlying facts.

Questions From Ferguson

Peter Van Buren | Posted 01.25.2015 | Crime
Peter Van Buren

Why did the grand jury take it upon themselves to sort out the witness conclusively? The point of a grand jury is only to determine if probable cause of a crime, a very low legal hurdle, exists. If it does, they return an indictment and the case goes to trial for resolution.
