In this video, Philip Baron, Associate Professor at the University of Johannesburg demonstrates Turnitin’s limitations by testing its ability to detect paraphrased and rephrased content created using QuillBot, raising concerns about potential academic misconduct.

Key Points for Educators

• Turnitin Detection Gaps: While Turnitin initially flagged the directly copied text at 94% similarity, QuillBot-paraphrased content dropped the similarity score significantly, showing only 31% similarity.

• Effectiveness of Rephrasing: After an additional rephrase, Turnitin no longer recognized the original source, revealing a gap in detecting extensively paraphrased content.

• Academic Integrity Concerns: The video highlights how rephrasing tools can help students bypass plagiarism detection, suggesting a need for new strategies to uphold academic integrity
