At the start of each school year, I spend time introducing my students to Turnitin.com, a program that I use to allow students to upload and submit their work. In addition to being a plagiarism checker, the program itself has some interesting features, including commenting, checking for grammar/usage and peer revision. There is also a way to link common core rubrics to an assignment for assessment purposes. Although I have dabbled in using most of its features, I would have to say that within the context of my classroom, Turnitin.com serves two primary purposes: it is a plagiarism checker and a database for storing student papers.
I am pretty excited about this multimodal tutorial because it is definitely something that I will use during the first week of school. In it, I teach students how to create a new account and upload an assignment. My primary audience is ninth graders who are new to Turnitin.com.
