We study same-sex role model effects of teachers with a meta-analysis and our own study of three million students in 90 countries. Both approaches show that role model effects on performance are, on average, small: 0.030 SD in the meta-analysis and 0.015 SD in our multi-country study. Going...

The idea that students benefit from same-sex teachers has motivated policies around the world aimed at reducing gender inequalities. However, we do not know the size or generalizability of such same-sex teacher effects. We fill this gap by conducting a meta-analysis and our own study using data...

The Dunning–Kruger effect states that low performers vastly overestimate their performance while high performers more accurately assess their performance. Researchers usually interpret this empirical pattern as evidence that the low skilled are vastly overconfident while the high skilled are...
