I've heard that girls learn better in an all-girl classroom setting, but that boys learn better in a mixed boy/girl classroom composition. Is there any statistical evidence that this lends merit to this argument? What factors were measured, and what is the psychological explanation behind the findings?

    Boys in same-sex settings do not feel the need for aggressive and showy behavior to impress girls, and girls do not feel the need to behave cute and stupid. That's why in some cases both genders do better. Single-gender classes is a bad idea for other reasons though, it's better to have one class and sometimes split it. However I can't find the research that is the source for these statements, so it's not an answer but a comment. Apr 9, 2011 at 7:48

    And "ratio"? Wouldn't "mixed vs same-gender education" be a better title? It's not like 35% girls is gonna make a difference vs 45% girls. :) Apr 9, 2011 at 7:49
  • @Lennart - Good point, I changed the title..

  • One day, I hope we will see classes with kids that learn the same way. Some kid can sit down for hours and some must move and touch. It's not about gender, but personality. These personality trait tend to be generalized by gender.

The answer depends a lot on the culture the children are raised in. For example, when working with children raised in a culture where strict gender roles are the norm, and boys and girls aren't normally allowed to socialize with one another, I found that children performed considerably better when segregated by sex. Boys and girls just weren't sure how to act one another, and they were wasting processor cycles on that instead of their schoolwork.

On the other hand, when working with children raised in a culture where sex roles were not so divided (boys and girls might favor different toys, but they socialized freely and didn't see one another as foreign and confusing), I found no difference in the performance of same-sex and mixed classroom in aggregate.

However this isn't great anecdotal evidence, because I never experienced a case where classrooms segregated by sex were taught the same material the same way. In every case, girls' classes centered around language skills and promoted conservative strategies, while boys' classes emphasized math and science and promoted risk-taking. This could be interpreted to mean that girls and boys raised in strict sex roles have different educational needs, or it could be interpreted to mean that girls and boys raised that way appear to perform better when the subjects and strategies stereotypically associated with the other gender (and bearing a stigma for their own gender) are de-emphasized.

As a side note, though the question only addressed educational performance, I felt the need to address the impact on socialization between the sexes as well. In both settings, children educated in same-sex settings had trouble working with the opposite sex in a professional setting as adults (some got over it with experience, some didn't, and it was far more pronounced in cultures with strict sex roles). Additionally, teenagers who spent their entire childhoods in same-sex education tended to have more stereotypical views of the opposite sex: this was adaptive in a society where those stereotypes were the only permitted behavior, it was like learning a script you would have to perform later, but was maladaptive in a more varied society where both boys' and girls' real behavior was more individual.

    Good answer. If you can cite references or be more specific about where your findings come from, how the study was conducted, and what the sample size was (particularly in the 4th paragraph) I'll vote you up.

  • @Javid I'm sorry if I was unclear: these are not the results of a formal study, but of my observations working in several different schools. The studies I have seen fall equally often on either side -- in favor of segregation or in favor of mixing -- in my opinion, because to my knowledge none of them look at the cultural aspect.

  • Interesting to see this come up today, because I read an article just this week about how "separate but equal" classrooms may not be such a good idea. If I can find it again I'll post a link.

  • +1 For the fourth paragraph! I was raised in a conservative society and went to a all-girls school. I found it real hard to interact with boys/men when I went on for course work and then work in Engineering. There was nothing malicious from the boys, its just the awkwardness of spending all day in a male-dominated environment. Fortunately, my family pushed me to go for advanced degree, otherwise, who knows, I might have dropped out at undergratuate level.

Most of my queries on Google Scholar returned results for a very specific age group (grade school, college, etc), subject (science, computer skills, etc), or learning approaches/settings (in-class instruction, small group projects, etc). Finding a more broadly-scoped experiment or observational study on this topic would require quite a bit of digging, and perhaps some help from a subject librarian at your local library or college/university.

HedgeMage mentioned the distinction between academic learning and social learning, and I would like to underscore this distinction. The answer to your question will likely be different if you only care about academic performance vs if you only care about social development vs if you care about overall performance/development. Complicating the matter further, both academic performance and social development can be broken down into multiple categories (exposure to facts/ideas, development of important technical skills, ability to work with others, respect for other people, respect for other cultures, etc). And there are probably other aspects of the educational process that I'm not even considering now!

This is probably why it will be difficult to find any statistical evidence for a broadly-scoped study of this topic, and why so many of the studies focus on specifics. It might be worth looking at a few different studies that approach the topic from different angles.


The earlier answers are way too complicated for a parent in the U.S. seeking practical advice. So here goes:

I taught in mixed, all-girls, and all-boys high schools, and substituted in middle schools, and I can say categorically, at least at the middle and high-school level, that for the vast majority of students, the best classroom is the one with the highest possible number of girls.

For boys in virtually any subculture in the U.S., the presence of girls is a moderating/civilizing influence, making the classroom easier to manage and thus to learn in.

For girls, the absence of boys increases civility with the aforementioned benefits, with the added benefit that they are dramatically more likely to get the teacher's attention and high expectations.

It's really that simple. I have little doubt that my observations apply equally to college undergrad. I'm less sure about elementary.

Full disclosure: not atypically for public school teachers, who send their own children to private schools at twice the rate of the general population (think about that before you send your precious little one to public school, please), I spend a large percentage of my after-tax income to send my daughter to an all-girls school. I believe she's worth it.


I went to an all-boys elementary school and a mixed high school, so I have very personal experience with both.

IMO, the main downside of an all-boys school is that it makes you unfamiliar with the ways of the female gender. If you're a male geek (like myself), going to an all-boys school doesn't exactly help make you feel less socially awkard among girls... quite the contrary!

On the other hand, being in the same class with peers of the opposite gender can be very distracting, especially during puberty. Also, boys and girls tend to learn very differently and mature at a different rate. This can complicate matters significantly when putting boys and girls in the same class.

So what is better? If your kid has siblings of the opposite gender and feels comfortable around peers of the opposite gender, I would recommend same-gender classroom. However, if your kid has no siblings of the opposite gender and/or is known to feel uncomfortable around peers of the opposite gender, it may be better to send him/her to a mixed classroom.

In the end, I don't believe there's a "one-size-fits-all" solution.
