Does teacher gender affect student learning?

A recent study slated for publication in the quarterly journal Education Next has generated headlines nationwide. "The Why Chromosome: How a Teacher's Gender Affects Boys and Girls," by Thomas Dee, associate professor at Swarthmore College and visiting scholar at Stanford University, suggests that a significant correlation exists between the gender of the teacher and the success of the student -- that is, girls learn more from women and boys learn more from men.

Though the study's author warns against jumping to conclusions based on his findings, they've nevertheless stirred up concern and provoked discussion. Have you seen evidence during your career as an educator, or when you were a student, that supports the findings of Dee's study? We're interested in your opinion.
