Turnitin helps develops your skills as a writer as well as using information effectively and ethically. It helps you to use 'your own words' and to reference other authors' work in your writing. These are important skills in developing critical literacy and to avoid plagiarism.
Your teacher will direct you to submit assignments to Turnitin via Canvas. The submitted work is then compared to a enormous database of web, journal and academic content to assess similarities to other works.
You can submit work to Turnitin more than once, however, second and subsequent submissions may take 24 hours to be processed.
