Using Originality Checking in D2L

D2L refers to plagiarism detection as "originality checking." If you select this option within a dropbox folder's settings, D2L will check all files that students submit for matches in TurnItIn's database of Internet sources, academic journals and publications, and student papers. TurnIt​In works for the following document types: MS Word, WordPerfect, PostScript, PDF, HTML, RTF, and plain text.

TurnItIn provides an overall originality score, which counts all matched text in a document, even if it is properly cited. Always look at the full originality report to verify plagiarism. It will highlight match text and provide a link to the original source.

  1. Click the dropdown arrow next to a dropbox folder's name, then select Edit Folder. The Edit Folder page will open.

  5. View Plagiarism Reports

    Originality reports can take time to generate after a file has been submitted to TurnItIn. Usually it only takes a few minutes, but sometimes it can take up to 24 hours.

    1. Click the name of a Dropbox folder to view the files submitted to it.
    2. Look at the list of submissions on the lower part of the page. The percentage in the “TurnItIn Similarity” column indicates the percent of the paper that TurnItIn matched in its database. Please know that if you enable plagiarism detection after students have already submitted files, you will need to click the icon in this column to submit the file to TurnItIn manually.
    3. Click the colored box to the right of the percentage in the “TurnItIn Similarity” column  to see the full originality report.

    If your report indicates that one of your student's files matches another student's file in TurnItIn's database, you will need to ask FITS  to obtain a copy of the file.
