Are teachers *generally* better at teaching students of their own sex?

NO in primary education,
YES in secondary education.

A 🧵generalizability and same-sex teacher effects

New working paper! We ran a field experiment with >1,300 university students randomly assigned to online vs in-person lectures in first-semester courses. What happens? Online instruction hurts performance, but only for women♀️📉

New research alert! Our study investigates the effectiveness of human-only, AI-assisted, and AI-led teams in assessing the reproducibility of quantitative social science research. We've got some surprising findings!

[Düsseldorf Institute for Competition Economics @DICEHHU]

We are very excited to welcome @EconFeld to our #ResearchSeminar today. He will give a talk on “On the generalizability of sex-differences in risk-attitudes”. The seminar takes place from 14:15 to 15:30 in room S3/4 in the Oeconomicum (building 24.31).

Better scientific writing causes better evaluations, and is associated with more citations

We had games in Munich earlier this week. 60+ participants reproducing 15 studies (3 econ, 4 poli sci and 8 psych articles)!

Some papers did not reproduce, missing data/codes, 2x revealed identity of participants, errors, etc.

A couple of thoughts from our chair (AB). 🧵

I’m very happy to introduce our new WP with @yveszenou1, @BhagyaGunaward5 and @sofoklis_goulas! We study the impact of being randomly assigned to a classroom with a same-gender top-performing student on short- & long-term educational outcomes. #EconTwitter @MonashBusiness

Job-market candidates:

- Download 10 JMPs in your field, read them in ≤5 hours, and rank them from best to worst. Now you know why recruiting committees value readability.

- Editing improves paper quality. See RCT: https://t.co/MUtlvXcr4b

🌞 Summer's heating up at IZA! 🔥 A huge welcome to our fantastic visiting researchers this month! Special shoutout to @EconFeld who's joining us for the rest of the year! We're excited to have you all! ✨

[Jan Feld @EconFeld]

really important work!

[Doug Campbell @TradeandMoney]

How credible was the "credibility revolution"? How robust is empirical research in economics? We just replicated a year's worth of the American Economic Review & had economists predict robustness. Here's what we learned. https://t.co/kOWJvSa6vJ

[NBER @nberpubs]

In Taiwan, disadvantaged minorities lower student effort, parental investments, and teacher engagement in classrooms to which they are randomly assigned, and this lowers student test scores, from @adegendre, @chriskarbownik, @nsalamancaa, and @yveszenou1 https://t.co/PMYzemxz9g

[David Evans @DaveEvansPhD]

It's great to see a meta-analysis and multi-country study verify more robustly what @ALeNestour & I observed in our quick @CGDev look at whether women teachers are better for girls' education (yes in secondary; no in primary): https://t.co/cBrakkvhMf

[Giuseppe Sorrenti @giu_sorrenti]

Very thought-provoking paper by an amazing team of economists! A must read... (independently of your sex😜)

[Nathan Kettlewell @NathanKettlewe1]

Very impressive research by Jan and the team, which they just keep improving (I discussed a version of this paper two years ago and it was an epic then).

[Ruben C. Arslan @rubenarslan]

Very impressive online supplement and not just because the Shiny app actually responds quickly.

[Nicolas Salamanca @nsalamancaa]

Our work with @AdeGendre, @chriskarbownik and @yveszenou1 combines a simple model and awesome data to show how and why disadvantaged minorities in the classroom to affect behaviors of students, parents and teachers, and ultimately test scores. Check it out!

[Nicolas Salamanca @nsalamancaa]

New work with awesome coauthors @AdeGendre, @EconFeld and @uZoelitz exploring the generalizability of same-sex teacher effects by combining existing multi-country data and met analysis tools. Check out the thread below!

[Jan Feld @EconFeld]

In secondary education, same-sex teacher effects are generally positive for all outcomes.

For test scores, effects even appear constant (and tiny) across all included countries.

[Jan Feld @EconFeld]

Taken together, our paper allows us to provide evidence for the following phenomenon:

Same-sex teacher effects are positive in secondary education.

“In secondary education” is a boundary condition of the phenomenon. It tells us where we should expect it to hold.
