All our sons' school teachers have been women, which is typical. In our experience, the best teachers have been women who are raising, or have raised, sons. The experience of raising little boys is the best way to learn what makes them tick and what is normal boy behavior. These teachers tend to adapt their teaching styles to support boys to a greater extent. They're also less likely to get upset over normal boyish behavior.
Even though I grew up with a brother, I really didn't understand the depth of differences between boys and girls. Until I had sons of my own, I didn't fully appreciate the hard-wired differences in the brains and bodies of boys and girls. My husband has had the last laugh hearing me admit that!
