Module 5: AI Tools for Detecting Plagiarism & Academic Integrity

Lesson 5.3: How to Read and Interpret AI Detection Reports

Learning Objectives

By the end of this lesson, educators will be able to:

• Understand how AI detection scores are generated.
• Interpret similarity and AI probability ratings accurately.
• Distinguish between plagiarism detection and AI-generated text detection.
• Use detection reports as supporting evidence, not automatic proof.
• Communicate findings fairly and transparently with students.

1. Detection Reports: What They Actually Measure

AI detection tools do not determine guilt—they identify patterns.

There are two types of detection reports:

2. Understanding Similarity Scores

A similarity score measures how much of a submission matches existing texts.

Important: Similarity ≠ cheating.

Quotes, references, and templates can raise similarity scores legitimately.

3.Understanding AI-Generation Probability Scores

AI detection reports often provide:

• Perplexity Score: Measures how predictable the text is.
• Burstiness Score: Measures variation in sentence style.

AI writing tends to be even, polished, and pattern-consistent, while human writing shows variation and irregularity.

4. Best Practices for Interpretation

1. Never rely solely on the detection score.
2. Compare writing style to the student’s previous work.
3. Ask the student to explain their work (verbal or short written reflection).
4. Use reports as conversation starters, not accusations.

5. Common Misinterpretations to Avoid

6.Key Takeaway

AI detection reports are supportive evidence, not final judgments.

Educators must interpret data thoughtfully, compare writing patterns, and combine AI tools with human evaluation and open communication.

Conclusion

AI detection reports are useful tools for monitoring academic integrity, but they are not absolute proof of plagiarism or AI misuse. Educators must interpret scores thoughtfully, compare against student writing history, and communicate openly before drawing conclusions. When combined with human judgment and ethical guidance, these tools help promote fairness, trust, and responsible use of AI in learning environments.
