Using the Writing Program Website
There are a few different resources on the Writing Program website that I think can be useful for students who are approaching or working on a draft.

For starters, you might have students visit particular Tutorama's. I find this especially useful around the third or fourth papers. By then, I have a sense of what each student needs to work on, so I can send them to a particular tutorama: one that will help feed them directly into their drafts.

The Gradatorium is useful in a similar way. Not only does it provide students with an introduction to grading, but it also serves to model the kinds of writing they should be doing in their drafts. I might ask them to look at a particular paper for a quick discussion of what makes it (or its project or a paragraph) strong or weak. Then I might ask them (in class or in the computer classroom) to produce writing based on that model.

Finally, the different questions located in the Link-O-Mat's are a great way to get students brainstorming and working on connections, projects, and paragraphs that can build into a draft.
