CHAPTER 1 OF 12 · Back to contents
1. Separate the two truth checks
First decide whether the assertion is true. Then decide whether the reason is true. Do not let confidence in one statement spill automatically into the other.
Build the explanation by naming the assertion and proposed reason as separate claims and the truth of each claim and the link required between them. A remembered keyword is not enough: connect the observation to the mechanism and identify what would have to change for the conclusion to change.
Repair the nearest misconception by checking the because test mechanism equation textual evidence or controlled comparison and returning to relevance direction causation sufficiency hidden assumptions counterexamples units scope and alternative explanations. State why the tempting alternative is too strong, incomplete or about a different stage.

2. Test the explanatory link
After both claims pass, ask whether the reason answers why the assertion occurs. A related fact can be true without supplying the mechanism or logical step needed.

State why the tempting alternative is too strong, incomplete or about a different stage.
CHAPTER 3 OF 12 · Back to contents
3. Use the because sentence
Read assertion because reason. If the combined sentence changes direction, omits a necessary step or merely places two facts together, the explanation is invalid or incomplete.

4. Apply subject-specific bridges
English needs textual or grammatical connection, Mathematics needs a valid operation or theorem under its conditions, and Science needs a mechanism or controlled causal relation.

5. Check direction
A reason may be an effect rather than a cause, or a conclusion rather than a premise. Reverse-direction evidence does not become explanatory simply because both ends are true.

CHAPTER 6 OF 12 · Back to contents
6. Look for hidden assumptions
Write the missing bridge explicitly. If it requires an unstated fact, a changed variable or an unsupported universal rule, the proposed reason does not yet explain the assertion.

CHAPTER 7 OF 12 · Back to contents
7. Distinguish relevance from sufficiency
A reason can be relevant and still incomplete. State what it contributes, what remains missing and whether the final claim should be narrowed.

CHAPTER 8 OF 12 · Back to contents
8. Audit the final response
Label assertion, reason and link; test truth separately; run the because sentence; state the bridge; reject or qualify the explanation if alternatives remain.

9. Worked examples
Worked case 1: Assertion: 12 is even. Reason: 12 is greater than 10. Are both true?
Controlled answer. Yes. Each statement is independently true.
Mechanism. Identify the exact relationship, apply the relevant rule and preserve every stated condition. A surface clue may be compatible with several explanations, so the answer must show what makes this case decisive.
Misconception repair. Do not turn partial evidence into complete proof. Name the closest wrong answer, identify its missing condition and explain why the observed evidence supports the narrower conclusion.
Transfer. Now test whether the reason explains evenness. Solve the altered case from the mechanism rather than copying the previous wording.
Explanation standard. A complete explanation names the observation, connects it to the rule and limits the conclusion to what follows. It should remain valid if decorative details are removed. If the explanation depends on the story topic instead of the decisive relation, rebuild it.
Audit. Recheck the assertion and proposed reason as separate claims, the truth of each claim and the link required between them, the because test mechanism equation textual evidence or controlled comparison, relevance direction causation sufficiency hidden assumptions counterexamples units scope and alternative explanations. Decide whether the evidence proves the conclusion or only supports a limited statement.

10. Independent practice
Practice 1: In English, what usually supplies the bridge?
Explained answer. Grammar, word meaning, sentence structure or textual evidence. A quotation must be interpreted rather than merely copied.
Delayed transfer. Explain one verb choice. Cover the answer later and rebuild the chain.
Control question. Which exact condition does the nearest wrong answer miss? State it before checking.
Extension. Change one decisive feature while keeping the story similar. Explain why the conclusion now stays or changes.
Independent proof. Restate the answer without copying its wording. Your version must identify the evidence, the governing relationship and the boundary of the claim. Then write one fact that would be relevant but still insufficient on its own. This separates explanation from repetition.
Delayed comparison. Save this item beside the near-nonexample you created. On the next attempt, compare them before answering and point to the single feature that controls the difference. If more than one feature changed, revise the pair so the comparison stays fair.
Practice 2: A plant grew taller and received more water. Does extra water explain the growth?
Explained answer. Not by those facts alone. Other variables changed or the water may not be the decisive cause.
Delayed transfer. Design a fair comparison. Cover the answer later and rebuild the chain.
Control question. Which exact condition does the nearest wrong answer miss? State it before checking.
Extension. Change one decisive feature while keeping the story similar. Explain why the conclusion now stays or changes.
Independent proof. Restate the answer without copying its wording. Your version must identify the evidence, the governing relationship and the boundary of the claim. Then write one fact that would be relevant but still insufficient on its own. This separates explanation from repetition.
Delayed comparison. Save this item beside the near-nonexample you created. On the next attempt, compare them before answering and point to the single feature that controls the difference. If more than one feature changed, revise the pair so the comparison stays fair.
Practice 3: A learner got the right answer because the handwriting was neat. Valid explanation?
Explained answer. No. Neat handwriting may help communication but does not establish the mathematical reasoning.

Practice 4: What if the reason explains only part of the assertion?
Explained answer. Qualify the claim and name the missing part. Partial explanation should not be presented as complete.
Delayed transfer. Split a compound assertion. Cover the answer later and rebuild the chain.
Control question. Which exact condition does the nearest wrong answer miss? State it before checking.
Extension. Change one decisive feature while keeping the story similar. Explain why the conclusion now stays or changes.

Practice 5: Why check scope words such as all and always?
Explained answer. A reason that supports one case may not justify a universal assertion. Scope mismatch makes the link too strong.
Delayed transfer. Narrow all to some. Cover the answer later and rebuild the chain.
Control question. Which exact condition does the nearest wrong answer miss? State it before checking.
Extension. Change one decisive feature while keeping the story similar. Explain why the conclusion now stays or changes.

Practice 6: How can units expose a broken explanation?
Explained answer. Incompatible units can show that the proposed relation or equation is invalid. Dimensional consistency is one link check.
Delayed transfer. Audit a speed formula. Cover the answer later and rebuild the chain.
Control question. Which exact condition does the nearest wrong answer miss? State it before checking.
Extension. Change one decisive feature while keeping the story similar. Explain why the conclusion now stays or changes.

Delayed comparison. Save this item beside the near-nonexample you created. On the next attempt, compare them before answering and point to the single feature that controls the difference. If more than one feature changed, revise the pair so the comparison stays fair.
Practice 8: State the full method.
Explained answer. Separate assertion and reason, verify each independently, combine them with because, demand the subject-appropriate bridge, test direction conditions counterexamples and alternatives, then accept reject or qualify the explanation. The method turns two plausible sentences into a checkable reasoning chain.
Delayed transfer. Apply after a delayed mixed-subject set. Cover the answer later and rebuild the chain.

11. Delayed transfer
On day one, solve clear examples. On day three, mix examples, near-nonexamples and incomplete evidence. On day seven, solve without headings or a word bank. Delay reveals whether the method can be reconstructed independently.
Keep an error log for the first failed stage: reading, representation, rule, execution or checking. The earliest failure identifies the repair.
Interleave this skill with neighbouring ideas that share vocabulary. Classify each item only after naming the distinguishing condition.
In timed work, mark the relationship, apply the rule, write the conclusion and audit one condition. If checking changes the answer, record the overlooked feature.
Create a teach-back card with a near-nonexample on the front and the repaired mechanism on the back. Explain why the tempting answer fails.
Finish with one basic example, one boundary case and one transfer case. Supply explanations that a classmate can verify.
For a second delayed test, reverse the direction: start from a conclusion and invent evidence that would justify it, then evidence that would be insufficient. This exposes the boundary between relevance and proof.

12. Family guidance and FAQs
Guidance for parents and tutors
Ask for the decisive condition before confirming the answer. Use prompts such as “What exactly happened?”, “Which stage or meaning is this?” and “What would prove it?”
Fade support from labelled examples to mixed questions and delayed open response. Independent retrieval after time and topic change is the target.
Praise precise claim control. Narrowing an answer when evidence is incomplete is scientific and academic strength.
Frequently asked questions
Should I memorise the rule?
Memorise the compact rule, then practise examples and near-nonexamples so the conditions remain visible.
What if two answers seem possible?
Return to the exact relationship and choose the option satisfying every stated condition without adding facts.
Why delay practice?
Immediate repetition may depend on the recent explanation; delay tests reconstruction.
How should an error be corrected?
Name the first failed stage and practise it with a changed example.
When is the skill ready?
When the learner can explain, apply and transfer it after a delay.
What is the final audit?
Check relationship, mechanism, claim strength and whole-question fit.
