While working on my PhD, I sat in on an educational psychology course required of all education majors. It was there that I discovered just how important the subject was for teachers, and just how little the students understood the psychology of teaching. Each student in the class had to present a paper on the subject "The most important thing a teacher must have". Out of the 30+ presentations, not one mentioned respect. The sad thing was the professor didn't mention it in classroom lectures either.
In the years following that course, I have found respect missing in most public, private and christian schools, and sadly, most homes.
