Due Date Information for Turnitin Assignments

This post will provide you with important information related to due dates within a Turnitin-enabled assignment.

When you add or change a due date on a Turnitin-enabled assignment by clicking, you can only add or change the due date for the entire assignment. When a due date is added to an assignment, the date is transferred from Canvas to the Turnitin LTI tool. Turnitin settings only allow one due date while Canvas allows multiple due dates. In addition, if you edit an assignment’s due date, it will transfer to the Turnitin LTI tool.

You won’t be able assign a different due date to an individual student. Turnitin only allows one due date on an assignment, so additional due dates for individual students won’t transfer to the Turnitin LTI tool. This can only be done on non-Turnitin-enabled assignments.

Turnitin File Type and Size Requirements

If you’re enabling Turnitin on an assignment, it will be helpful to know its file size and type requirements.

File Size

If your assignment allows any file type, the following sizes will be accepted by Turnitin in order to generate an Originality Report.

  • Less than 40mb.
  • Has a minimum of 25 words.
  • Is less than 400 pages in length.

File Type

The following files types will be accepted by Turnitin in order to generate an Originality Report.

  • Microsoft Word documents (.doc / .docx)
  • Adobe PDFs (.pdf) – PDF image files, fillable forms, files that don’t contain highlightable text (i.e., scanned file), or files created with software other than Adobe Acrobat are not accepted.
  • Microsoft PowerPoint files (.ppt, .pptx, .ppsx, .pps) – Turnitin will convert a PowerPoint file into a static PDF, leaving all text and images in their original format. Features such as presenter notes, embedded video, and animations will not be visible. In addition, any visual effects (i.e., shadows and 3D) should be removed prior to submitting the file.
  • Microsoft Excel spreadsheets (.xls / .xlsx)
  • HTML files
  • Rich Text Format files (.rtf)
  • Plain Text files (.txt)
  • Google Docs from Google Drive – Third-party cookies must be allowed by your Internet browser; otherwise, Google sign-in attempts will fail.
  • OpenOffice Text documents (.odt)
  • WordPerfect files (.wpd)
  • PostScript files (.ps / .eps)
  • Hangul Word Processor files (.hwp)

The following file types are not acceptable and will not generate an Originality Report from Turntiin.

  • Password protected files
  • Microsoft Works files (.wps)
  • Microsoft Word 2007 macro-enabled files (.docm)
  • OpenOffice text files created and downloaded from Google Docs (.odt)
  • Documents created using OpenOffice (.doc) – These documents are not 100% Microsoft Word equivalent.
  • Apple Pages
  • Spreadsheets created outside Microsoft Excel (e.g., .ods)
  • Text with visual effects

If your student must convert a file to a new file format (extension), he / she should rename the file with a name other than that of the original file. This helps prevent loss of the original formatting or image content of a file.

Please contact us if you have any questions about enabling Turnitin on an assignment.

Update to Grades Page in Canvas

Quick Tip: Submitting Multiple Files to an Assignment

Do you have an assignment that requires students to submit multiple files? This is not an issue if the assignment doesn’t have Turnitin enabled. By default, Turnitin doesn’t accept multiple file. When Turnitin is enabled, only one file is able to be submitted to an assignment by a student. We don’t want to discourage you from using Turnitin for assignments, so we’re providing you with a couple recommendations when your assignment requires the submission of multiple files.

  • Create an assignment with Turnitin enabled for each file the student needs to submit.
  • Ask students to combine their files into one file to submit.

Please contact LDT with questions about Turnitin and/or Canvas.

Previewing Quizzes in Canvas

You can preview quizzes in the Canvas desktop version. Previewing a quiz allows you to take a quiz as if you were the student, including submitting the quiz. Don’t worry, an official quiz submission isn’t created in Canvas.

Using Firefox for Grading

You can absolutely use Firefox to grade items in SpeedGrader. Chrome is preferred, but there are plenty of faculty who use Firefox without any issues. There are a couple things to keep in mind when using Firefox for grading.

  • To avoid losing any annotations, click off the comment and onto the screen before moving to the next student.
  • When entering a grade, make sure you see the page refresh before moving to the next student.

Coming Soon: Turnitin Similarity Scoring Improvements

Beginning in March, Turnitin will make some improvements to bring you a more reliable matches and a comprehensive Originality Report.

The improvement includes when bibliographic material is excluded from an Originality Report, Turnitin recalculates the Similarity Score based on the remaining content only. This will provide you with a more accurate score. When you select the option to exclude bibliographic materials from Similarity Index for all papers in an assignment, you are choosing to exclude text appearing in the bibliography, works cited, or references sections of student papers from being checked for matches when generating Originality Reports.

For example, opting to exclude a bibliography that constitutes 10% of a paper will generate a report according to 90% of that paper, rather than calculating reports out of 100%.

For assignments that have not yet passed their due dates, all reports will automatically regenerate in line with the improvement. Reports for closed assignments will not be updated. If you extend a closed assignment’s due date, you are reopening the assignment, and all reports in the assignment will regenerate to align with the update. If you have open assignments, log in to check regenerated reports, as the update may cause a slight increase to a paper’s Similarity Score.
