Turnitin tracking how students turn in assignments to combat AI

Greetings from the ASCILITE 2024 conference at University of Melbourne. I had intended to go to a research talk, but I couldn't find the "Light Green Room", so I stumbled into a presentation from Turnitin on their AI detection tool (this is in a room with check green carpet & mould coloured roundell patterned wallpaper, so I don;t know what it is called). 

Last year Turnitin released an AI writing report with paraphrase detection. This did not appear to work well and ANU decided to switch it off. But perhaps it is time to look at the product again and see if now works acceptable. One aspect I had difficulty understanding is Turnitin is addressing paper based assessment (are universities really returning to paper based assessment.

Turnitin are building a student composition space. The idea is the student writes their assignment within Turnitin. This is an implementation of the "show your work" approach. The tool will have a word processing function. With this approach you can see when the student did what. 

Turnitin are also building an offline digital exam system. This is similar to standalone products already in use. 

A new similarity report is al in the works for Turnitin. One small example is allowing for margin comments.
