I'm also teaching a newspaper course next semester. I bought a textbook called "High School Journalism" by Homer L. Hall; I'll probably use it as a guide/resource as I teach (there is no journalism textbook for students in my school). Also, try looking at past issues of the school newspaper, if there is one. My school newspaper is more of a newsletter - photocopied on 8x10 sheets with no color - rather than an actual newspaper. Anyway, good luck with your course!
