Thinking about the process of writing

Here's a literary magazine devoted to the process of writing. It's probably not for students, but it could certainly be helpful for teachers as they write.

Welcome to 
draft: The Journal of Process

Featuring stories, first drafts, and interviews with authors of note, draft is a unique print publication emphasizing the importance and diversity of the creative process. We’re interested in mechanics, techniques, approaches, triumphs, failures, concussive frustration — everything that goes into crafting a great piece of creative writing.
