To put it simply, based on the current research... No.
Boys and girls do not actually learn in different ways, and there is no evidence to support the idea that students are "more distracted" around members of the opposite sex. Things like the number of students to teacher ratio and method of instruction are so much more important.
If anyone's interested, I'd suggest reading
Pink Brain, Blue Brain by Lise Eliot for an excellent summary of gender differences in development.
