Find your route through this guide
This volume solves one precise learner problem: the learner reads “on the strength of” as physical power or treats it as a guarantee that a decision is correct, instead of identifying the stated evidence, merit, record or reputation used as its basis. The goal is durable control, not a remembered slogan. A Primary 6 learner should be able to identify the trigger, explain the mechanism, perform the decision under time pressure and reject an attractive answer that exceeds the evidence.
- Start with the exact mistake and the evidence boundary.
- Build the mechanism before memorising a shortcut.
- Study worked contrasts and name why the near-miss fails.
- Repair misconceptions with one targeted check each.
- Attempt graded independent practice before reading the explanations.
- Return after a delay and prove that the method transfers.
- Use the parent and tutor notes after the learner has attempted the work.
The problem beneath the mistake
“Maya was chosen on the strength of her clear presentation and careful research” means those qualities supported the choice. Nobody measured the power of her muscles.
The expression normally follows a decision, belief, opportunity or action and introduces the basis that made it possible or persuasive.
The noun after “of” often names evidence, a result, a record, a recommendation, a reputation or a demonstrated ability. Context tells us which kind of support matters.
Strength is figurative here: the supporting basis is treated as having persuasive force. That force can be strong without being physical.
The phrase does not automatically mean the named factor was the only consideration. Words such as “solely” or “alone” are needed to establish exclusivity.
It also does not prove the decision was wise. A passage may later show that the evidence was incomplete, the reputation outdated or the judgement mistaken.
A strong comprehension answer identifies both sides of the relation: what happened and what supported it. Quoting only the phrase leaves the mechanism unstated.
The expression is different from “with all her strength”, which describes effort or physical force, and from “strengthen”, which names an action that makes something stronger.
It can be used for favourable and unfavourable outcomes. A claim may be accepted on the strength of reliable records, or a weak decision may be criticised because it rested on one untested report.
The relevant support must be local to the sentence or passage. Do not import a different achievement merely because it also sounds impressive.
In cloze work, the grammar is useful: “on the strength of” is followed by a noun phrase, while the surrounding clause usually contains the action or judgement it supports.
The reliable routine is action, supporting basis, support type, scope and evidence audit.
Core decision: Read “on the strength of” as “because of the supporting evidence, merit, record or reputation named next”. Identify the supported action and its basis, then keep separate questions about exclusivity, reliability and correctness.
Figurative prepositional phrases compress relationships. Accurate reading expands the phrase into a complete causal or evidential link without adding claims the wording does not contain.
Mechanism: why the rule works
1. Locate the supported action
Find the decision, belief, selection or opportunity in the main clause.
The phrase cannot be interpreted safely without knowing what received support.
Diagnostic check. What happened on this basis?
2. Name the basis
Read the noun phrase after “of” and state it precisely.
A vague answer such as “because it was strong” hides the evidence.
Diagnostic check. Which result, record, quality or testimony is named?
3. Classify the support
Decide whether the basis is direct evidence, demonstrated merit, past performance, recommendation or reputation.
Different support types deserve different checks.
Diagnostic check. What kind of reason is doing the work?
4. Test the figurative sense
Replace the phrase with “because of the persuasive support provided by”.
If the sentence remains coherent, physical force is not intended.
Diagnostic check. Would muscles or applied force make sense here?
5. Protect scope
Keep the basis attached only to the named decision or claim.
One strong performance does not establish every ability or future result.
Diagnostic check. Exactly what conclusion does this support reach?
6. Check exclusivity
Look for “solely”, “alone” or another limiter before claiming there was only one reason.
The phrase can foreground a basis without excluding others.
Diagnostic check. Does the text say this was the only factor?
7. Audit reliability
Ask whether the supporting material is current, relevant, sufficient and independently checked.
A phrase can report a decision without endorsing it.
Diagnostic check. Is the basis trustworthy enough for the conclusion?
Worked examples: make the decision visible
Pause before each answer. State the controlling evidence in one line, then complete the operation. The explanations deliberately contrast a valid route with a plausible but invalid one, because transfer grows when the learner can say why a tempting route does not apply.
Worked example 1: Selection
Task. Interpret: “Ravi joined the team on the strength of his trial performance.”
Reasoning. The trial performance supplied demonstrated evidence relevant to selection.
Answer. Ravi was selected because his trial performance supported the decision.
Independent check. Do not claim it was the only criterion unless the passage says so.
Contrast-and-transfer pass. Keep the governing principle from “Selection”, but change one surface detail in the task: Interpret: “Ravi joined the team on the strength of his trial performance.” Before recalculating or rewriting, name which evidence remains controlling and which detail has changed. The original conclusion—Ravi was selected because his trial performance supported the decision.—may remain valid only if the changed detail does not alter the trigger, relationship or scope. Use the independent check again rather than trusting visual similarity. This second pass trains selection: the learner must decide whether the same method still applies, adapt one step when a condition changes, and refuse the method when its trigger disappears.
Worked example 2: Scholarship
Task. A pupil receives an interview on the strength of a thoughtful portfolio.
Reasoning. The portfolio displays merit and earns the next opportunity; it does not guarantee the scholarship.
Answer. The portfolio supported the invitation to interview.
Independent check. Keep the conclusion at interview, not final award.
Contrast-and-transfer pass. Keep the governing principle from “Scholarship”, but change one surface detail in the task: A pupil receives an interview on the strength of a thoughtful portfolio. Before recalculating or rewriting, name which evidence remains controlling and which detail has changed. The original conclusion—The portfolio supported the invitation to interview.—may remain valid only if the changed detail does not alter the trigger, relationship or scope. Use the independent check again rather than trusting visual similarity. This second pass trains selection: the learner must decide whether the same method still applies, adapt one step when a condition changes, and refuse the method when its trigger disappears.
Worked example 3: Recommendation
Task. The committee shortlists a project on the strength of two expert recommendations.
Reasoning. The recommendations are reported support, not the project itself.
Answer. They helped justify shortlisting.
Independent check. Expert status does not remove the need to inspect the project.
Contrast-and-transfer pass. Keep the governing principle from “Recommendation”, but change one surface detail in the task: The committee shortlists a project on the strength of two expert recommendations. Before recalculating or rewriting, name which evidence remains controlling and which detail has changed. The original conclusion—They helped justify shortlisting.—may remain valid only if the changed detail does not alter the trigger, relationship or scope. Use the independent check again rather than trusting visual similarity. This second pass trains selection: the learner must decide whether the same method still applies, adapt one step when a condition changes, and refuse the method when its trigger disappears.
Worked example 4: Reputation
Task. Customers visit a shop on the strength of its reputation.
Reasoning. Reputation influences their action even before personal experience.
Answer. The shop’s reputation motivates the visit.
Independent check. A good reputation does not guarantee every visit will be good.
Contrast-and-transfer pass. Keep the governing principle from “Reputation”, but change one surface detail in the task: Customers visit a shop on the strength of its reputation. Before recalculating or rewriting, name which evidence remains controlling and which detail has changed. The original conclusion—The shop’s reputation motivates the visit.—may remain valid only if the changed detail does not alter the trigger, relationship or scope. Use the independent check again rather than trusting visual similarity. This second pass trains selection: the learner must decide whether the same method still applies, adapt one step when a condition changes, and refuse the method when its trigger disappears.
Worked example 5: Evidence
Task. A conclusion is drawn on the strength of repeated measurements.
Reasoning. The measurements are empirical support for that specific conclusion.
Answer. The conclusion rests on the repeated data.
Independent check. Check that the measurements actually address the variable in question.
Contrast-and-transfer pass. Keep the governing principle from “Evidence”, but change one surface detail in the task: A conclusion is drawn on the strength of repeated measurements. Before recalculating or rewriting, name which evidence remains controlling and which detail has changed. The original conclusion—The conclusion rests on the repeated data.—may remain valid only if the changed detail does not alter the trigger, relationship or scope. Use the independent check again rather than trusting visual similarity. This second pass trains selection: the learner must decide whether the same method still applies, adapt one step when a condition changes, and refuse the method when its trigger disappears.
Worked example 6: Physical near-miss
Task. “The climber pulled with all her strength.”
Reasoning. This describes effort and force, not an evidential basis.
Answer. Do not replace it with “on the strength of”.
Independent check. Grammar and meaning both differ.
Contrast-and-transfer pass. Keep the governing principle from “Physical near-miss”, but change one surface detail in the task: “The climber pulled with all her strength.” Before recalculating or rewriting, name which evidence remains controlling and which detail has changed. The original conclusion—Do not replace it with “on the strength of”.—may remain valid only if the changed detail does not alter the trigger, relationship or scope. Use the independent check again rather than trusting visual similarity. This second pass trains selection: the learner must decide whether the same method still applies, adapt one step when a condition changes, and refuse the method when its trigger disappears.
Worked example 7: Weak support
Task. A rumour is accepted on the strength of one anonymous message.
Reasoning. The sentence reports the basis but also reveals its weakness.
Answer. The claim was accepted because of a single unverified message.
Independent check. Reporting a basis is not approving it.
Contrast-and-transfer pass. Keep the governing principle from “Weak support”, but change one surface detail in the task: A rumour is accepted on the strength of one anonymous message. Before recalculating or rewriting, name which evidence remains controlling and which detail has changed. The original conclusion—The claim was accepted because of a single unverified message.—may remain valid only if the changed detail does not alter the trigger, relationship or scope. Use the independent check again rather than trusting visual similarity. This second pass trains selection: the learner must decide whether the same method still applies, adapt one step when a condition changes, and refuse the method when its trigger disappears.
Worked example 8: Not exclusive
Task. A school chooses a venue on the strength of safety records and later mentions price and location.
Reasoning. Safety records are important, but the later factors show the decision was multi-causal.
Answer. Do not paraphrase with “only because”.
Independent check. Search the wider passage for other reasons.
Contrast-and-transfer pass. Keep the governing principle from “Not exclusive”, but change one surface detail in the task: A school chooses a venue on the strength of safety records and later mentions price and location. Before recalculating or rewriting, name which evidence remains controlling and which detail has changed. The original conclusion—Do not paraphrase with “only because”.—may remain valid only if the changed detail does not alter the trigger, relationship or scope. Use the independent check again rather than trusting visual similarity. This second pass trains selection: the learner must decide whether the same method still applies, adapt one step when a condition changes, and refuse the method when its trigger disappears.
Worked example 9: Scope
Task. A writer is invited to speak on the strength of one well-researched article.
Reasoning. The article supports the invitation to speak about the relevant topic.
Answer. It does not prove expertise in every subject.
Independent check. Match the support to the bounded conclusion.
Contrast-and-transfer pass. Keep the governing principle from “Scope”, but change one surface detail in the task: A writer is invited to speak on the strength of one well-researched article. Before recalculating or rewriting, name which evidence remains controlling and which detail has changed. The original conclusion—It does not prove expertise in every subject.—may remain valid only if the changed detail does not alter the trigger, relationship or scope. Use the independent check again rather than trusting visual similarity. This second pass trains selection: the learner must decide whether the same method still applies, adapt one step when a condition changes, and refuse the method when its trigger disappears.
Worked example 10: Outdated record
Task. A choice is made on the strength of results from ten years earlier.
Reasoning. The results are the stated basis, but currency is doubtful.
Answer. The phrase explains the choice while allowing criticism of its evidence.
Independent check. Separate meaning from evaluation.
Contrast-and-transfer pass. Keep the governing principle from “Outdated record”, but change one surface detail in the task: A choice is made on the strength of results from ten years earlier. Before recalculating or rewriting, name which evidence remains controlling and which detail has changed. The original conclusion—The phrase explains the choice while allowing criticism of its evidence.—may remain valid only if the changed detail does not alter the trigger, relationship or scope. Use the independent check again rather than trusting visual similarity. This second pass trains selection: the learner must decide whether the same method still applies, adapt one step when a condition changes, and refuse the method when its trigger disappears.
Worked example 11: Paraphrase
Task. Rewrite: “The plan proceeded on the strength of the pilot results.”
Reasoning. Expand the relationship without changing its certainty.
Answer. “The plan proceeded because the pilot results provided support for it.”
Independent check. Do not upgrade support into proof.
Contrast-and-transfer pass. Keep the governing principle from “Paraphrase”, but change one surface detail in the task: Rewrite: “The plan proceeded on the strength of the pilot results.” Before recalculating or rewriting, name which evidence remains controlling and which detail has changed. The original conclusion—“The plan proceeded because the pilot results provided support for it.”—may remain valid only if the changed detail does not alter the trigger, relationship or scope. Use the independent check again rather than trusting visual similarity. This second pass trains selection: the learner must decide whether the same method still applies, adapt one step when a condition changes, and refuse the method when its trigger disappears.
Worked example 12: Cloze control
Task. Complete: “She earned a place ___ her consistent work.”
Reasoning. The sentence needs a phrase linking the place to a demonstrated basis.
Answer. “On the strength of” fits.
Independent check. The following noun phrase supplies the support.
Contrast-and-transfer pass. Keep the governing principle from “Cloze control”, but change one surface detail in the task: Complete: “She earned a place ___ her consistent work.” Before recalculating or rewriting, name which evidence remains controlling and which detail has changed. The original conclusion—“On the strength of” fits.—may remain valid only if the changed detail does not alter the trigger, relationship or scope. Use the independent check again rather than trusting visual similarity. This second pass trains selection: the learner must decide whether the same method still applies, adapt one step when a condition changes, and refuse the method when its trigger disappears.
The method lab: change one condition at a time
Build a controlled comparison around this problem: the learner reads “on the strength of” as physical power or treats it as a guarantee that a decision is correct, instead of identifying the stated evidence, merit, record or reputation used as its basis. Write one clear case, one near-miss and one neighbouring case. Change only one decisive condition between adjacent examples. Predict first, then name the evidence that would reverse the decision. The boundary should become visible rather than remaining a memorised slogan.
Turn the central claim into a decision card: Read “on the strength of” as “because of the supporting evidence, merit, record or reputation named next”. Identify the supported action and its basis, then keep separate questions about exclusivity, reliability and correctness. Put the trigger question on the front. On the back, write the mechanism, one worked example, one near-miss and the limit. Test both directions: rule to example and example to rule.
Make an evidence ladder with four rungs: observation or given information, interpreted relationship, conclusion and independent check. If two rungs repeat the same idea, rewrite one so it performs a distinct job. Strong reasoning moves forward rather than echoing the question.
Construct two tempting wrong answers. Identify the exact decision where each fails, explain why it looks plausible and write the smallest repair. Change the surface details and repeat so the correction transfers beyond one familiar item.
Teach the idea aloud in ninety seconds without notes. Include the controlling condition, mechanism, example, near-miss and one sentence beginning “This does not mean…”. Repair only the missing link, then teach the complete chain again more concisely.
After two days, attempt one direct item, one disguised item and one item where the rule should not be used. Write the method choice before solving. After one week, rebuild the rule on a blank page and verify it by a different route.
Common misconceptions and targeted repairs
Misconception 1: Physical strength
What the learner may think. The phrase describes muscle power.
Why it fails. In decision and evidence contexts, strength is figurative persuasive force.
Targeted repair. Replace it with “because of the support provided by”.
Misconception 2: Proof guaranteed
What the learner may think. A strong basis makes the conclusion certainly true.
Why it fails. Support can be relevant yet incomplete or misleading.
Targeted repair. Audit sufficiency and reliability separately.
Misconception 3: Only reason
What the learner may think. The named factor excludes every other consideration.
Why it fails. Exclusivity needs explicit wording.
Targeted repair. Look for “solely”, “only” or wider reasons.
Misconception 4: Any achievement
What the learner may think. One success supports any later opportunity.
Why it fails. The basis must be relevant to the decision.
Targeted repair. State the exact ability or conclusion supported.
Misconception 5: Always praise
What the learner may think. The phrase approves the basis.
Why it fails. It can report a weak or criticised decision.
Targeted repair. Read the writer’s evaluation around it.
Misconception 6: Reputation equals evidence
What the learner may think. What people believe is direct proof.
Why it fails. Reputation is one support type and may need checking.
Targeted repair. Classify the basis before judging it.
Misconception 7: Effect omitted
What the learner may think. The learner names the evidence but not what it supported.
Why it fails. A complete relation needs both sides.
Targeted repair. Write “X happened because Y supported it”.
Misconception 8: Strengthen confusion
What the learner may think. The phrase and the verb “strengthen” do the same grammatical job.
Why it fails. One introduces a basis; the other describes change.
Targeted repair. Check sentence structure and time.
Graded independent practice with explained answers
Attempt each item without looking ahead. Write the evidence or relationship before the final response. Early items check recognition; middle items require explanation; later items change the surface form so that copying a worked example is insufficient.
Practice 1: Meaning
Question. What does the phrase usually introduce?
Explained answer. The evidence, merit, record or reputation supporting an action or judgement.
Why this earns trust. The figurative relationship is explicit.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat “The evidence, merit, record or reputation supporting an action or judgement.” from memory, but to recreate a justified answer from the new evidence.
Practice 2: Action
Question. In “selected on the strength of her trial”, what is supported?
Explained answer. Her selection.
Why this earns trust. The main-clause outcome is identified.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat “Her selection.” from memory, but to recreate a justified answer from the new evidence.
Practice 3: Basis
Question. What supplies support in that sentence?
Explained answer. Her trial performance.
Why this earns trust. The noun phrase after “of” is used.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat “Her trial performance.” from memory, but to recreate a justified answer from the new evidence.
Practice 4: Physical contrast
Question. Is “lifted it with all his strength” the same expression?
Explained answer. No.
Why this earns trust. That sentence concerns physical effort.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat “No.” from memory, but to recreate a justified answer from the new evidence.
Practice 5: Exclusivity
Question. Does the phrase mean “only because of”?
Explained answer. Not by itself.
Why this earns trust. Exclusivity requires extra wording.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat “Not by itself.” from memory, but to recreate a justified answer from the new evidence.
Practice 6: Reliability
Question. Can a decision be made on weak support?
Explained answer. Yes.
Why this earns trust. The phrase reports the basis without certifying it.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat “Yes.” from memory, but to recreate a justified answer from the new evidence.
Practice 7: Reputation
Question. Is reputation identical to direct evidence?
Explained answer. No.
Why this earns trust. It is a different type of support.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat “No.” from memory, but to recreate a justified answer from the new evidence.
Practice 8: Scope
Question. A strong art portfolio proves excellence in every subject. True?
Explained answer. No.
Why this earns trust. Keep the conclusion relevant and bounded.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat “No.” from memory, but to recreate a justified answer from the new evidence.
Practice 9: Paraphrase
Question. Give a safe replacement.
Explained answer. “Because of the supporting force of” or simply “because of”.
Why this earns trust. The action-to-basis relation remains.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat ““Because of the supporting force of” or simply “because of”.” from memory, but to recreate a justified answer from the new evidence.
Practice 10: Cloze
Question. Complete: “The experiment was repeated ___ the surprising first result.”
Explained answer. “On the strength of” can fit if the result supplied the reason to repeat.
Why this earns trust. Grammar and relation are coherent.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat ““On the strength of” can fit if the result supplied the reason to repeat.” from memory, but to recreate a justified answer from the new evidence.
Practice 11: Evaluation
Question. What four checks test the basis?
Explained answer. Currency, relevance, sufficiency and independent verification.
Why this earns trust. Meaning and evidence quality are separated.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat “Currency, relevance, sufficiency and independent verification.” from memory, but to recreate a justified answer from the new evidence.
Practice 12: Inference
Question. Can we infer the choice succeeded later?
Explained answer. No.
Why this earns trust. The phrase explains a basis, not the future outcome.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat “No.” from memory, but to recreate a justified answer from the new evidence.
Practice 13: Tone
Question. Is the phrase always positive?
Explained answer. No.
Why this earns trust. Context may praise or criticise the decision.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat “No.” from memory, but to recreate a justified answer from the new evidence.
Practice 14: Routine
Question. State the audit.
Explained answer. Action, basis, support type, scope and reliability.
Why this earns trust. Every hidden assumption becomes visible.
Transfer variation. Close the answer, wait several minutes, and rebuild the reasoning with different names, values or wording while preserving the same decision. Start by stating the evidence that activates the method; then produce the response and a separate check. If the new surface detail changes the governing condition, explain why the earlier answer pattern must not be copied. The aim is not to repeat “Action, basis, support type, scope and reliability.” from memory, but to recreate a justified answer from the new evidence.
A four-session mastery cycle
Session 1: construct. Read the mechanism once, cover it and write a three-line model containing the trigger, the operation and the check. Add one example and one near-miss. Compare only after the model is complete. If the operation is right but the trigger is missing, the knowledge is unsafe because it may be applied in the wrong place.
Session 2: discriminate. Mix six items: two that clearly require this method, two that tempt the method but violate a condition, and two that require another skill. For every item, write “use” or “do not use” before answering. Accuracy in method selection matters more than speed at this stage.
Session 3: explain. Give a complete answer to an imagined classmate. Include the smallest sufficient evidence, the mechanism and the independent check. Remove any sentence that merely repeats the question or adds an unsupported claim. A concise causal explanation is stronger than a longer collection of familiar words.
Session 4: perform. Attempt a timed mixed set without notes. Mark uncertain decisions, but continue. During review, classify each error as trigger, evidence, operation, scope, unit or check. Reattempt one changed version after a delay. Mastery is shown when the learner chooses and adapts the method without needing the original example beside it.
Delayed transfer: prove that the learning lasts
Transfer test 1: Changed context
Apply the idea in a fresh context after two days.
Success criterion. Trigger, mechanism and limit are stated.
Transfer test 2: Near-miss audit
Explain why a tempting example fails.
Success criterion. The exact failed condition is named.
Transfer test 3: Independent check
Verify by a second route.
Success criterion. The check does not repeat the same mistake.
Transfer test 4: Blank recall
Rebuild the idea after one week.
Success criterion. Definition, example, near-miss and boundary appear.
Examination control
1. Find the main-clause action. State what was selected, believed, offered or continued.
2. Underline the noun after “of”. That phrase names the support.
3. Classify the support. Evidence, merit and reputation require different checks.
4. Protect scope and exclusivity. Do not add “only” or widen the conclusion.
5. Evaluate separately. Explaining why a decision occurred is not endorsing it.
Under time pressure, compress the method to undefined. The compressed routine is useful only after the full reasoning is understood. If it produces uncertainty, expand the step instead of guessing.
A compact error log
Label the failed decision rather than writing “careless”. A precise error label makes the next practice item useful.
Reattempt one changed version after a delay. Mastery requires method selection, not recognition of the original wording.
Notes for parents and tutors
Ask for controlling evidence before accepting the answer.
Let the learner attempt a near-miss before explaining again.
Praise precise limits and checks, not speed alone.
Use fresh contexts so the decision transfers.
