More practice with the language you're learning
Supplementary support — grammar, vocabulary, speaking and review — built from language already taught in the course. Not a lesson, and never a test.
1.Transformation: express the same meaning without repeating the original wording — "**Scope**: On the measures used and within the age cohorts observed, the AI-tutor effect is positive and stable."
2.Transformation: express the same meaning without repeating the original wording — "**Strength**: The effect is small but stable across replications; we are not yet in a position to call it large."
3.Transformation: express the same meaning without repeating the original wording — "**Mechanism**: The pattern is consistent with the engagement hypothesis but does not yet diagnose engagement as the mechanism; alternative explanations remain live."
4.SCOPE hedge: 'Reading fiction improves empathy.'
Show answer
'On the short-term measures used in this literature, and in the populations sampled, reading fiction is associated with improvements in perspective-taking.'
5.MECHANISM hedge: 'Density causes loneliness.'
Show answer
'Density is consistently correlated with loneliness in our data, but the design does not allow us to identify density as the mechanism rather than a marker of other features of dense neighbourhoods.'
6.Mini-context: someone disagrees with you in a meeting. Reply in two turns, using this structure at least once.
Show answer
Calibrated hedging at C2: (a) SCOPE HEDGE ('within the limits of the sample…' / 'on the measures used…' / 'for the cohorts observed'); (b) STRENGTH HEDGE ('robust at conventional levels' / 'a small but stable effect'); (c) MECHANISM HEDGE ('consistent with X, but not yet diagnostic of X' / 'we observe the pattern, not the mechanism'); (d) GENERALISABILITY HEDGE ('we hesitate to extend this to populations not represented in the sample'). Each hedge adds information about WHY the claim is uncertain.
1.Sort these into "positive", "neutral" and "critical" in tone, and be ready to defend a borderline case: epistemic hedge, to overclaim (the result), scope condition(s), to under-power (a study), preregistered (analysis / hypothesis), boundary condition
Show answer
epistemic hedge — a hedge about what is known | to overclaim (the result) — to state more than the evidence supports | scope condition(s) — the boundaries within which a claim is meant to hold | to under-power (a study) — to design a study with too few observations to detect the effect | preregistered (analysis / hypothesis) — specified in advance to prevent post-hoc cherry-picking | boundary condition — the specific case where a claim stops holding
2.Odd one out: which of these is least like "epistemic hedge" in meaning or use — to overclaim (the result) / scope condition(s) / to under-power (a study)? Explain why.
Show answer
Compare against: a hedge about what is known
3.Odd one out: which of these is least like "to overclaim (the result)" in meaning or use — scope condition(s) / to under-power (a study) / preregistered (analysis / hypothesis)? Explain why.
Show answer
Compare against: to state more than the evidence supports
4.Odd one out: which of these is least like "scope condition(s)" in meaning or use — to under-power (a study) / preregistered (analysis / hypothesis) / boundary condition? Explain why.
Show answer
Compare against: the boundaries within which a claim is meant to hold
5.Odd one out: which of these is least like "to under-power (a study)" in meaning or use — preregistered (analysis / hypothesis) / boundary condition / epistemic hedge? Explain why.
Show answer
Compare against: to design a study with too few observations to detect the effect
6.Semantic map: place "epistemic hedge" on a scale from mild to strong against two other words you know. Then use the strongest one.
7.Semantic map: place "to overclaim (the result)" on a scale from mild to strong against two other words you know. Then use the strongest one.
8.Semantic map: place "scope condition(s)" on a scale from mild to strong against two other words you know. Then use the strongest one.
9.Mini-dialogue: write four lines in which two of this lesson's words appear naturally.
1.Word family: give the noun, verb, adjective and adverb forms linked to "epistemic hedge" where they exist, then use the form that is hardest for you.
2.Word family: give the noun, verb, adjective and adverb forms linked to "to overclaim (the result)" where they exist, then use the form that is hardest for you.
3.Word family: give the noun, verb, adjective and adverb forms linked to "scope condition(s)" where they exist, then use the form that is hardest for you.
4.Word family: give the noun, verb, adjective and adverb forms linked to "to under-power (a study)" where they exist, then use the form that is hardest for you.
5.Spot the mismatch: which partner does NOT work with "epistemic hedge" — and what would a proficient speaker say instead?
Show answer
Natural model: An epistemic hedge restricts the claim; an interactional hedge softens the tone.
6.Spot the mismatch: which partner does NOT work with "to overclaim (the result)" — and what would a proficient speaker say instead?
Show answer
Natural model: The headline overclaims; the paper itself is more careful.
7.Spot the mismatch: which partner does NOT work with "scope condition(s)" — and what would a proficient speaker say instead?
Show answer
Natural model: The paper specifies three scope conditions for the claim.
8.Rewrite one sentence from your last piece of writing, swapping a weak combination for a precise one from this lesson.
1.Shift the register twice: make this markedly formal, then markedly conversational — "**Scope**: On the measures used and within the age cohorts observed, the AI-tutor effect is positive and stable."
2.Shift the register twice: make this markedly formal, then markedly conversational — "**Strength**: The effect is small but stable across replications; we are not yet in a position to call it large."
3.Shift the register twice: make this markedly formal, then markedly conversational — "**Mechanism**: The pattern is consistent with the engagement hypothesis but does not yet diagnose engagement as the mechanism; alternative explanations remain live."
4.Diplomatic vs direct: soften this, then sharpen it. Which version would you actually use, and to whom? "Where does the original hedge ADD information?"
5.Compress: express the idea behind "An epistemic hedge restricts the claim; an interactional hedge softens the tone." in six words or fewer without losing the nuance.
Show answer
a hedge about what is known
6.Compress: express the idea behind "The headline overclaims; the paper itself is more careful." in six words or fewer without losing the nuance.
Show answer
to state more than the evidence supports
7.Compress: express the idea behind "The paper specifies three scope conditions for the claim." in six words or fewer without losing the nuance.
Show answer
the boundaries within which a claim is meant to hold
8.Read one of your own paraphrases aloud. Which word choice is doing the most work? Replace everything around it.
1.Rank and justify: order the ideas in Where does the original hedge ADD information? / Which hedge could be cut without loss? / What does the over-claim risk that the over-hedge does not — and vice versa? from most to least convincing. Defend your top choice.
2.Role-play: Three minutes prep on your strongest position + your strongest concession. Take the position you least agree with.
3.Decision task: you have two minutes to reach a single recommendation on An 80-word joint statement + one note on the hedge each side called theatre.. State it in one sentence.
4.Now switch sides and argue the opposite for 60 seconds. Which language had to change?
5.Follow-up — push further: Claim: a four-day-week trial improved measured wellbeing. Add a counter-example.
6.Follow-up — push further: Claim: an app intervention reduced reported anxiety. Add a counter-example.
1.Paragraph ordering: draft your four topic sentences only, then decide their best order and say why.
2.Partial writing: write only the concession paragraph of Write a 250–280-word discussion section for a paper (real or invented). You MUST: (a) state your finding cleanly BEFORE hedging, (b) include at least one scope, one mechanism and one generalisability hedge, (c) avoid 'may possibly' entirely, (d) name one next step, (e) use at least three target items. — 60–80 words.
3.Editing pass: cut 15% of your words without losing content. What went first?
4.Audience switch: rewrite your opening for a hostile reader, then for a sympathetic one.
5.Self-check: underline every repeated word and replace two with precise choices from this lesson.
1.Imagine an academic talk on AI literacy in schools. Draft and read aloud ONE scope hedge that would change a multiple-choice answer.
Show answer
Listen for SCOPE hedges as anchor points for which answer is right.
2.Find the evidence: which exact words in the text/script support this — Why does the writer state the findings BEFORE hedging?
Show answer
To force the hedges to be about the findings, not to bury them — and to keep the reader from confusing caution with absence of claim.
3.Find the evidence: which exact words in the text/script support this — Identify ONE SCOPE hedge.
Show answer
'The panel is restricted to consolidated democracies and we do not extend the claim to mixed regimes.'
4.Find the evidence: which exact words in the text/script support this — Identify ONE MECHANISM hedge.
Show answer
'the mechanism for asymmetry is not identified in the present design; we read the result as consistent with a loss-aversion account, without claiming to demonstrate it.'
5.Key word transformation: rewrite "**Scope**: On the measures used and within the age cohorts observed, the AI-tutor effect is positive and stable." using the structure from Methodological hedging: honest, not evasive, in 3–8 words.
Show answer
Calibrated hedging at C2: (a) SCOPE HEDGE ('within the limits of the sample…' / 'on the measures used…' / 'for the cohorts observed'); (b) STRENGTH HEDGE ('robust at conventional levels' / 'a small but stable effect'); (c) MECHANISM HEDGE ('consistent with X, but not yet diagnostic of X' / 'we observe the pattern, not the mechanism'); (d) GENERALISABILITY HEDGE ('we hesitate to extend this to populations not represented in the sample'). Each hedge adds information about WHY the claim is uncertain.
6.Reflection: which part of this task type costs you most time, and what will you do differently next time?
1.True, false or not stated? Decide for each, then correct the false ones: "To force the hedges to be about the findings, not to bury them — and to keep the reader from confusing caution with absence of claim." · "'The panel is restricted to consolidated democracies and we do not extend the claim to mixed regimes.'" · "'the mechanism for asymmetry is not identified in the present design; we read the result as consistent with a loss-aversion account, without claiming to demonstrate it.'"
Show answer
Why does the writer state the findings BEFORE hedging? → To force the hedges to be about the findings, not to bury them — and to keep the reader from confusing caution with absence of claim. | Identify ONE SCOPE hedge. → 'The panel is restricted to consolidated democracies and we do not extend the claim to mixed regimes.' | Identify ONE MECHANISM hedge. → 'the mechanism for asymmetry is not identified in the present design; we read the result as consistent with a loss-aversion account, without claiming to demonstrate it.'
2.Retrieval race: in 60 seconds, list every word from this lesson you can remember, then check what you missed.
Show answer
epistemic hedge, to overclaim (the result), scope condition(s), to under-power (a study), preregistered (analysis / hypothesis), boundary condition
3.Use "epistemic hedge" in a sentence about a completely different topic from the lesson.

Show answer
to state more than the evidence supports
5.Use "scope condition(s)" in a sentence about a completely different topic from the lesson.

the boundaries within which a claim is meant to hold
6.Teach it back: explain Methodological hedging: honest, not evasive to someone who has never met it, in under 45 seconds.
Show answer
Calibrated hedging at C2: (a) SCOPE HEDGE ('within the limits of the sample…' / 'on the measures used…' / 'for the cohorts observed'); (b) STRENGTH HEDGE ('robust at conventional levels' / 'a small but stable effect'); (c) MECHANISM HEDGE ('consistent with X, but not yet diagnostic of X' / 'we observe the pattern, not the mechanism'); (d) GENERALISABILITY HEDGE ('we hesitate to extend this to populations not represented in the sample'). Each hedge adds information about WHY the claim is uncertain.
7.Where in your past writing have you hedged with theatre rather than information?
