Single-sex = Pseudoscience

Joanne's on a roll today:

Single-sex education is based on “pseudoscience,” charge a team of neuroscience and child development experts in a Science article. There is “no empirical evidence” that segregating students by sex improves education, they argue. There’s plenty of evidence it can increase gender stereotyping among students and adults.

Short-term gains are attributed to the Hawthorne Effect, or to "motivate" evaluators. Commenters on Joanne's post question the bias of the study's authors.
