Valentine's Day is this Sunday. If you are spending it thinking about effect sizes or research designs or education policy, shame on you. Unless, of course, that sort of thing turns you on.

I suppose I might be more expert in randomized controlled trials if I had ever had the actual opportunity to fetch a pail of water without one when my...

Proven Programs vs. Local Evidence

Robert E. Slavin | Posted 01.21.2016 | Education
Robert E. Slavin

All evidence from rigorous studies is good evidence, as long as it addresses actionable policies or practices that could make a difference for student outcomes. However, there is a big distinction between two kinds of good evidence that I think it is useful to make.

The Future of Title I - 2040

Robert E. Slavin | Posted 01.14.2016 | Education
Robert E. Slavin

When you get to a certain age, you find increasing evidence that you've been yammering on the same topics for a very long time, usually to no great benefit. I just made one of those discoveries. Going through some old publications, I found a 1991 article I wrote on the future of Title I.

New Years Resolutions for Evidence-Based Reform

ESSA puts a lot of emphasis on moving power from Washington to the states, and even if this were not true, it is now time to advocate in state capitols for use of proven programs and evidence-informed decisions. In the states and even in Washington, evidence-based reform needs a lot more allies.

What Works, In Context

The public and private resources available to invest in reducing achievement gaps in education, teenage pregnancy rates, child poverty and any other cause are limited. Therefore, funding should be channeled to programs that are proven to be effective.

I was rather disheartened to discover that The New York Times decided to start off the year by pretending to dispel diet myths, while actually propaga...

From Instinct to Intelligence: A Scientific Approach to Social Media

Michael D. Shaw | Posted 12.30.2015 | Business
Michael D. Shaw

Whenever I read or hear executives commenting about social media, my first reaction is to revert to my college and graduate school studies in biochemistry: I look for the one thing every assertion requires and every hypothesis, no matter how elegantly stated or brilliantly illustrated, demands: Evidence.

Smart Philanthropy

The appearance of ImpactMatters could make a difference in philanthropy, and that would be terrific in itself. However, its significance goes far beyond philanthropy.

We have all heard that eating fish is good for us, and the proposition is valid both empirically, and epidemiologically. But it begs a vital question ...

My wife Nancy and I were recently in Barcelona, a beautiful and fascinating city famous for its innovations in architecture, art, and design. We were speaking to various groups about evidence-based reform in education and about cooperative learning.

Response to Intervention and Bob's Law

Robert E. Slavin | Posted 11.19.2015 | Education
Robert E. Slavin

The problem in education reform isn't a lack of good ideas. It's a lack of good ideas implemented with enough clarity, consistency and integrity to actually make a difference in rigorous experiments. A recent large-scale evaluation of Response to Intervention (RTI) illustrates this problem once again.

Wisconsin Needs and Deserves a Patients Reproductive Health Act

Sara Finger | Posted 11.17.2015 | Politics
Sara Finger

Wisconsin has joined the troubling national trend of enacting laws based on junk science under the false guise of protecting women's health. Sadly, the goal of these harmful laws is to restrict access and compromise women's reproductive health care.

Cleaning the House of Medicine

A recent report in JAMA Internal Medicine highlights prevailing medical practices that should be "reconsidered" in 2015 based on the weight of evidenc...

Random Thoughts

Robert E. Slavin | Posted 11.12.2015 | Education
Robert E. Slavin

While methodologists have long favored randomized over matched experiments, actual experience in education has been mixed, in the sense that in some systematic reviews of treatment studies, effect sizes were pretty much the same in randomized and matched studies.

Why Leave Learning to Chance?

Robert E. Slavin | Posted 10.29.2015 | Education
Robert E. Slavin

Why is it ok to leave the reading success of children to chance? Why don't we treat reading success the way we treat air safety, as something to ensure no matter what?

Evidence-Based Reform Is Irreversible

Robert E. Slavin | Posted 10.22.2015 | Education
Robert E. Slavin

For a long time, education has paid little attention to evidence. There are still far too few researchers, educators and policy-makers involved in the evidence movement.

What Does the Evidence Tell Us About Sexual Harassment in the Workplace?

Dr. Alessio J.G. Brown | Posted 10.15.2015 | Business
Dr. Alessio J.G. Brown

Although empirical evidence on the efficacy of workplace policies in reducing sexual harassment is limited, there is a consensus that emphasizing prevention, issuing strong policy statements of no tolerance, and providing safe complaint procedures protecting against retaliation can be considered best practices.

Columbus and Replicability

Robert E. Slavin | Posted 10.15.2015 | Education
Robert E. Slavin

What Columbus did discover was not America per se, but a replicable and openly published route to America. And that's what made him justifiably famous. The day he reached the New World was a significant event, but it wasn't really important until he showed that he (and anyone else) could do it again.

Beware of Do-It-Yourself Assessments

Robert E. Slavin | Posted 10.08.2015 | Education
Robert E. Slavin

It may be going too far to suggest that no one should ever use or accept experimenter-made measures, no matter how fair they appear to be to the experimental and control groups. However, what it does say is that we need to be very cautious in accepting experimenter-made measures.
