We are phasing in a long-awaited ‘originality checking’ function to TurnitinUK marking of coursework. This checks if the content of a piece of coursework matches other sources.
TurnitinUK produces a Similarity Report for the piece of coursework.
A typical submission made to an assignment in Turnitin generates a Similarity Report. The Similarity Report is the result of comparison between the text of the submission against the search targets selected for the assignment; this may include billions of pages of active and archived internet information, a repository of works previously submitted to Turnitin, and a repository of tens of thousands of periodicals, journals, and publications. Any matching or highly similar text discovered is detailed in the Similarity Report that is available in the Assignment Inbox.
The similarity score is a percentage of a paper’s content that matches to Turnitin’s databases; it is not an assessment of whether the paper includes plagiarized material. Both students and markers can run this report. It does not indicate whether plagiarism has occurred, but you can use it as an assistive tool to check work.
Below is a link to a very useful video for instructors, on how to view the similarity report in Feedback Studio, which is the improved version of Turnitin , going live on 1st August 2017.
‘How to View Similarity Reports (instructor)’:
Understanding the Report
Once the report is complete, the ‘Similarity’ column will show a percentage and a corresponding colour – see the screenshot below:
• Blue = no matching words
• Green = one matching word – 24% similarity index
• Yellow = 25 – 49% similarity index
• Orange = 50 – 74% similarity index
• Red = 75 – 100% similarity index
The higher the percentage, the greater the amount of text that matches content in Turnitin’s database. There is no ‘magic number’ for what percentage match the work should have. It is highly likely that some content in an assignment will match a small portion of Turnitin’s database.
For example, this could be as a result of
• bibliographical information
• common phrases such as ‘on the other hand’
• wording we expect you to use – such as on the coversheet, which every student uses.
Turnitin – New name
Turnitin has made some improvements, and is now being renamed ‘Feedback Studio’.
On 1 August 2017, Feedback Studio will become the marking interface for all Turnitin users. After this date, the Classic version of Turnitin will be retired.
All changes are to the feedback section of Turnitin, not to the page set up, or student submission area. The improvements provide a unified design for all feedback, without the need to swap between screens for information on similarity and student comments. It is possible to see similarity, ‘quick marks’, individual comments and even write directly onto the students paper, all on the same page.
We are really pleased about these changes which will make it much easier to use. For students, there will be no change to their submission process, only to the feedback they see.
