Turnitin updated last week, bringing a number of bug fixes and new features.
Grading without submission
Use Turnitin to give feedback to a student without them submitting a file. For example, you could use this to give feedback for a presentation in class – you could even grade on your iPad as the student was giving their presentation.
Submit any file type
The document viewer will contain a link to download the file, and an empty page – called a grading template – where you can use the regular Turnitin features to feedback.
