Fourth installment of blog series, "Turnitin Strategies in the Writing Process" by Mary Lawson, Professor of English at Houston Community College
In the previous two blogs, I discussed using the ETS e-rater for editing and using PeerMark to guide revision. After all of this work, students need to actually revise their essays. I have found a way using the Turnitin.com plagiarism detection software to check for amount of revision.
By this point, students will have submitted a rough draft. I usually require rough drafts to be 75% of the final essay count, so for an essay with 1000 words, the rough draft has to be 750 words. That shows them from the beginning that for the potential for full credit, they will have to do some work between the rough and the final drafts. In my classes, students originally enroll in a rough draft course and a final draft course, with drafts being submitted to the corresponding courses.
