They have opportunities to interact (group projects) without the pressure of being "on a date." b) Disadvantage is that less learning is going on. They distract each other and take focus off education. In a single-gender situation, the teaching style can be tailored to the gender. One example of this, depending on the individual students, is that boys tend to like action, girls like workbooks, that kind of thing. More learning is going on in single-gender classes, more focusing, less showing off, less socializing. Best to you.
