School Spirit

This is something that still baffles me. Being a student, I can’t say that I had very much of this. Being a teacher, I see now why this can be important. The students I teach who have it take pride in their work, in their appearance and are concerned with their results. They are just all-around more pleasant to teach.
I had classmates who had a lot of school spirit at my school and friends at other schools who did as well. I didn’t understand it then and still do not. Now, however, I see it as beneficial to the kids in this school. How can one instill school spirit? Can one instill a sense of pride? It’s on my mind and if the few people who read this have any thoughts, I’d love to hear them.
