Or comprehension and generation deviate
May fabricate sources, facts, or conclusions
Check evidence and specific results
Hallucination: AI may generate content that appears credible but is actually incorrect or unsubstantiated, such as citing sources that don't exist.
Confident Tone, Unsubstantiated Content
Imagine a lesson plan cites a specific page from a book, but you haven't provided that book and the system didn't actually find it. The complete book title and page number look credible, but they don't prove the citation is real.
Hallucinations can manifest as fabricated citations, incorrect facts, or judgments not supported by the materials. Not every unsuitable result is a hallucination: if a lesson plan's time arrangement deviates from requirements, it may primarily be a task understanding issue.
First Check Key Facts and Sources
For important names, dates, numbers, and quotations, go back to the original source to confirm. Check not only that the source itself exists, but also whether it supports the current claim. Even real webpages can be misread or cited for irrelevant content.
| Content in the Response | Helpful Checks |
|---|---|
| Specific historical citations | Find the original text, confirm wording and context |
| Textbook page numbers | Verify the edition of the textbook being used and the corresponding page |
| Judgments derived from materials | Distinguish between facts from the original text, reasonable inferences, and unverified speculation |
Improve Conditions, Keep Verifying
Providing relevant, reliable materials and asking the model to distinguish between supported claims and items to be checked can reduce certain sources of errors. Allowing "I'm not sure" is more appropriate than demanding a definite answer for every question when evidence is lacking.
But having materials, using tools, or providing lengthy prompts cannot guarantee zero errors. Searches can mismatch, materials can be outdated, and the model can also misinterpret.
Don't Attribute All Problems to the Model
If a file hasn't been generated, first check the tool results; if the time arrangement exceeds 40 minutes, first compare against the requirements; if a citation doesn't exist, go back to the source. Accurately identifying the problem is key to choosing the right fix.

Reflect
When AI provides seemingly complete reference book titles and page numbers, what's your next step?
Reference judgment: Actually look up the corresponding source and confirm it supports the claim; the completeness of the source format does not prove the source is real.
