In the latest Turnitin LTI 1.3<\/strong> update, the traditional “Match Overview” has been replaced by a more sophisticated system called Match Groups<\/strong>. Instead of just showing you a list of sources, Turnitin now automatically categorizes matching text based on how the student has used citations and quotation marks.<\/p>\n\n\n\n

This allows you to quickly distinguish between accidental plagiarism, poor paraphrasing, and correctly cited work.<\/p>\n\n\n\n

Understanding the 4 Match Groups<\/h2>\n\n\n\n

When you open the Similarity Report in the Next-Gen Feedback Studio, the right-hand panel (red icon) will display the Match Groups<\/strong> tab. The overall similarity score is now broken down into four distinct categories:<\/p>\n\n\n\n

    \n
  1. Not Cited or Quoted (Red):<\/strong> The most critical group. This highlights text that matches a source but has no citation and no quotation marks<\/strong>. These are high-priority areas to review for potential plagiarism.<\/li>\n\n\n\n
  2. Missing Quotation (Orange):<\/strong> Text that has an in-text citation but is not<\/strong> enclosed in quotation marks. This often indicates a student who has copied verbatim but forgot the quotes, or who has paraphrased too closely to the original.<\/li>\n\n\n\n
  3. Missing Citation (Yellow):<\/strong> Text that is enclosed in quotation marks but lacks an in-text citation<\/strong>. This is usually a formatting error where the student attributed the words but forgot the source reference.<\/li>\n\n\n\n
  4. Cited and Quoted (Blue):<\/strong> The “Safe” group. This highlights text that is correctly enclosed in quotes and has a corresponding citation.<\/li>\n<\/ol>\n\n\n\n

    Refining the Similarity Score<\/h2>\n\n\n\n

    The most powerful feature of Match Groups is the ability to “clean up” the similarity score to see the true area of concern.<\/p>\n\n\n\n

    How to refine the report:<\/strong><\/p>\n\n\n\n

      \n
    • In the Match Groups panel, you will see a percentage<\/strong> next to each of the four categories.<\/li>\n\n\n\n
    • Click the Eye Icon<\/strong> (Hide\/Show) next to the Cited and Quoted<\/strong> group.<\/li>\n\n\n\n
    • The overall similarity percentage at the top of the screen will instantly recalculate, excluding the correctly cited material.<\/li>\n<\/ul>\n\n\n\n
      \n

      Tip:<\/strong> By hiding the “Cited and Quoted” and “Bibliography” groups, the remaining percentage reflects only the problematic areas (Not Cited or Missing Quotes), giving you a much more accurate “integrity score” at a glance.<\/p>\n<\/blockquote>\n\n\n\n

      Navigating Source Cards<\/h2>\n\n\n\n

      Clicking on any of the Match Groups will open a list of Source Cards<\/strong> related to that specific category.<\/p>\n\n\n\n

        \n
      • Ranked List:<\/strong> Sources are ranked by the amount of matching text within that specific group.<\/li>\n\n\n\n
      • Navigation Arrows:<\/strong> Use the <<\/code> and ><\/code> arrows on a source card to jump directly to each instance of that match within the student's paper.<\/li>\n\n\n\n
      • Match Details:<\/strong> Each card tells you the total word count and the percentage of the paper that matches that specific source.<\/li>\n<\/ul>\n\n\n\n

        Match Groups vs. The \"Sources\" Tab<\/h2>\n\n\n\n

        While Match Groups<\/strong> is the best tool for checking integrity and finding teachable moments, you can still access the traditional view:<\/p>\n\n\n\n

          \n
        • The Sources Tab:<\/strong> Located next to the Match Groups tab at the top of the sidebar.<\/li>\n\n\n\n
        • What it does:<\/strong> It provides a simple, descending list of every source found in the paper, regardless of how it was cited. Use this if you want to see if a student has over-relied on a single source (e.g., if one source accounts for 40% of the entire paper).<\/li>\n<\/ul>\n\n\n\n
