My post in the Brookings ‘Evidence Speaks’ series on accumulating evidence of negative effects of private school vouchers. Four recent studies in three states and DC, all with the same outcome. It’s rare when evidence is so unified.
I wrote this piece for a conference on ‘scaling up’ at Vanderbilt in October 2015. Scaling up essentially uses knowledge gained in one context or several related contexts and casts it more broadly to other and larger contexts. There’s more to it of course, but the question is whether what works in one locale, for […]
I posted this piece in March 2017 as part of the Brookings ‘Evidence Speaks’ series. The piece contrasts the negligible results of a massive Federal infusion of funds for school improvement and recent studies that have measured how equalizing spending within states affected student outcomes.
The upshot is that money does matter, but going the […]
I posted this back in December 2016 as part of the ‘Evidence Speaks’ series for Brookings. Teacher observations take a lot of time and energy, but as I argue in the piece, what we’ve measured to date suggests we are observing teaching in ways that do not connect to student learning. Enjoy.
My recent post on comparability and Title I is here. Researchers have cautioned that correlations at high levels of aggregation do not need to be true at lower levels of aggregation, and can even reverse, Simpson’s paradox. And so we found with spending on teachers. When data are analyzed in the aggregate, it appears […]
My post on the Brookings Chalkboard about adding more research to the Elementary and Secondary Education Act.
It’s been years since No Child Left Behind pushed for more ‘scientifically based research.’ The world has moved on, of course. Now, lots of people are thinking about how to use big data, the web is everywhere, […]
My post here on the Brookings Chalkboard forum about the $1.2 billion program that doesn’t do anything for student outcomes.
Reactions were easily predicted. The afterschool program community trotted out its standard lines about kids needing to be safe, about how programs reduced exposure to crime and participation in delinquent activities, about kids […]
My post on the Bush Institute web site about annual testing. Looking at the numbers, annual testing does not take a lot of time away from classroom activities. But periodic benchmark testing, which a lot of districts are doing thinking they are preparing students for the annual test, may be taking a lot of […]
My post on the Brookings chalkboard about teacher preparation, an institution for which research and evidence are hurdles that test scores need to get over before programs will use them.
Which seems backward: why would test scores have to pass muster to be used as outcomes? Scores already are used as outcomes by teachers and schools. […]
