Tip #1: Your assignment should match your course goals/objectives. Don't "do" writing just to say you've done it.
Make sure it's going to help you with your bigger objectives in the course.
Tip #2: You don't need to be an expert yourself. No one expects you to be a grammarian. (In fact, plenty of English
teachers are stumped by our language at times.) If you need an expert, see tip #6, but really, just concentrate on what you need
from the paper. Give kids guidelines for the format, but don't make it your primary focus.
This is a pretty sweet collection of resources for teachers to cruise through and glean nuggets of cool for their students. All kinds of sites to support each stage of the writing process, as well as content from MI, OWL, and the like. As well as ways for students to get published, watch videos, and get creative.
I'm not a huge fan of lists, but this is a nice collection.
