I’m excited to share a new EdWorkingPaper with @andydebarros.bsky.social. Evaluations are an increasingly common way school systems globally are trying to help teachers improve, but is more always better? A 🧵 doi.org/10.26300/ms3...

Evaluation Scores and Student Learning under Compulsory Teacher Re-Evaluation

We examine how lower-performing public school teachers respond to more frequent formative evaluations. A 2011 reform in Chile required teachers rated "basic" (the second-lowest category) to be re-eval...

Our education policy group at BU Wheelock is accepting PhD applications this cycle. I'm particularly excited about synergies with the economics department that allow our students to do "economics of education" coursework. Spread the word and e-mail me if you're interested in learning more.

🧵 New DP from I4R co-director Lester Lusher, with Sonia Ale, Md Shafiqui Islam, Huda Osman & Jacob Stenstrom (Pitt): "When Samples Shape Significance." What happens when you re-estimate published results using fresh draws of the same data? Some evidence from Google Trends!

Excellent post. The “reflective” vs “formative” distinction is one I’ve tried to make in the past but not nearly as eloquently. And the fact that Anderson’s ICW index can dampen power by upweighting noise is an important problem that should be better understood.

Excited to see our study on four-day school weeks and teacher retention out at Education Finance & Policy! Using 18 years of data from Oregon, we find that switching to a four-day week actually increased teacher turnover by about 2 percentage points. direct.mit.edu/edfp/article... 1/4

Less Is More? The Causal Effect of Four-Day School Weeks on Teacher Turnover

Abstract. The use of four-day school weeks (4dsw) in the United States has expanded rapidly over the past two decades. Previous work examines the impact of 4dsw on student outcomes, but less research ...

Forthcoming in the AER: "The Effect of Omitted Variables on the Sign of Regression Coefficients" by Matthew A. Masten and Alexandre Poirier.

The Effect of Omitted Variables on the Sign of Regression Coefficients

(Forthcoming Article) - We show that, depending on how the impact of omitted variables is measured, it can be substantially easier for omitted variables to flip coefficient signs than to drive them to zero. This behavior occurs with “Oster’s delta” (Oster 2019b), a widely reported robustness measure. Consequently, any time this measure is large—suggesting that omitted variables may be unimportant—a much smaller value reverses the sign of the parameter of interest. We propose a modified measure of robustness to address this concern. We illustrate our results in four empirical applications and two meta-analyses. We implement our methods in the companion Stata module regsensitivity.

New research alert! Here’s the big idea: Will giving students the tools to master foundational math and reading skills serve as a building block for broader learning? @andydebarros.bsky.social & Theresa Lubozha set out to answer this by examining Zambia’s national “Catch Up” program.

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

It must be very hard to publish null results Publication practices in the social sciences act as a filter that favors statistically significant results over null findings. While the problem of selection on significance (SoS) is well-known in theory, it has been difficult to measure its scope empirically, and it has been challenging to determine how selection varies across contexts. In this article, we use large language models to extract granular and validated data on about 100,000 articles published in over 150 political science journals from 2010 to 2024. We show that fewer than 2% of articles that rely on statistical methods report null-only findings in their abstracts, while over 90% of papers highlight significant results. To put these findings in perspective, we develop and calibrate a simple model of publication bias. Across a range of plausible assumptions, we find that statistically significant results are estimated to be one to two orders of magnitude more likely to enter the published record than null results. Leveraging metadata extracted from individual articles, we show that the pattern of strong SoS holds across subfields, journals, methods, and time periods. However, a few factors such as pre-registration and randomized experiments correlate with greater acceptance of null results. We conclude by discussing implications for the field and the potential of our new dataset for investigating other questions about political science.

You're right, one does not necessarily imply the other; was running out of characters. Here'a link to my JMP, which I framed as being about school choice and sorting, but is also about tracking (across schools). We don't have a WP for the classroom tracking yet. Link to my JMP (accepted at ReStat):
