- 2Locate a limit
- 3Add a qualifier that names that limit
- 4Compare with vague hedging and keep the more informative wording
“The results suggest a relationship in these trials, but the small sample limits how confidently we can generalise.” This is more useful than repeatedly adding maybe.

EAL upgrade
Remove the qualifier list; learners decide whether and how the evidence needs qualification.
Keep the subject challenge. Offer one model, visual or language prompt where needed, then check a fresh independent response.

Teacher language
Adapt these prompts to the task and your learners.
Our purpose is: Use scientific hedging to name the limits of a result, rather than adding vague uncertainty everywhere.
What does the evidence establish, and where is its limit?
Try the new case on your own. Show the detail or reasoning that supports your answer.
Which support do you still need, and which part can you now do independently?
Across subjects
Science: distinguish a supported result from a general law. Humanities: qualify what one source can establish.
Adjust language support
Use a small word bank, visuals and partner rehearsal when needed. Extend with precise explanations and qualifications. Judge the support from the response to this task.
