I had a nightmare once.  I had just given birth to my second son and as wonderful as my boys are the nightmare started with them.  In this dream, I came home to a house full of boys.  Fifteen of them.  All mine.  I think I woke up screaming.  Although this scenario sends chills up and down my spine, it is exactly the direction that some schools are heading.  A new look at an old idea: single-gender classrooms.  In an article by Katherine Bradley, the description of an all-boy classroom seem pretty appealling.  Bradley describes this particular classroom as running "like a well-oiled machine".  I have never had the "pleasure" of teaching an all-boy class but I have come close.  In my experience, the dynamics are notably different when there are few females in the classroom, although not always in a positive way.  It is not a matter of like or dislike, I love my boys and some of my favorite students have been boys, but it comes down to being able to relate to your students and understand their motivation.   In the scenario described by Bradley there was a male teacher at the helm, steering the boys in the appropriate direction.  Perhaps that is the difference.  In a classroom where boys can openly relate to their male teacher the relationships are less strained and pressured.  I have had the pleasure of teaching an all-girl class.  Where the other instance strikes fear in my heart, I delight in the opportunity to teach a room full of girls.  In an atmosphere where there is no one to impress, girls are free to be themselves and to enjoy learning for the sake of learning.  Don't misunderstand.  I love my boys and I enjoy teaching both genders as they bring excitement and energy to the classroom.  However, I think that single-gender classrooms are best left up to a teacher of that same gender.
