A marked paper is not merely a record of what went wrong. Read carefully, it is a map of decisions: where the learner selected the wrong evidence, overreached an inference, lost a reference chain, compressed the wrong point, built an example that proved nothing, or knew the English but could not retrieve it under pressure.
This Secondary English Diagnostic & Repair Handbook has one distinct job in the eduKateYishun library: turn completed work into the next useful teaching action. It complements the Secondary 1–4 Learning System rather than competing with it. The question here is: what failed, why might it have failed, what is the smallest useful repair, and what fresh task would show that the repair can travel?
The method is evidence-led: observe → describe → hypothesise → probe → teach → reconstruct → vary → delay → mix → retire or repeat. A wrong answer does not automatically prove carelessness, and a corrected answer does not prove independent control.
Start with the evidence
Preserve the first attempt. Describe the observable decision instead of labelling the learner. “Selected a true detail from the wrong event” is more useful than “careless.” “Added a plausible motive not supported by the passage” is more useful than “weak inference.” “Example shares the topic but does not prove the reason” is more useful than “poor writing.”
Test the suspected mechanism with two or three small fresh items before building a large intervention. If the predicted error repeats, confidence in the hypothesis increases. If it disappears, reconsider the original context.
Choose the first consequential bottleneck
A marked paper can contain many imperfections. Teach the mechanism that is frequent, consequential, foundational or likely to affect several components. Protect secure skills and move them into mixed work rather than continuing unnecessary drills.
Reading repair
Repair question boundaries before answer wording: identify person, time, event, relationship and scope. For inference, compare claims of different strength and ask what the text actually supports. For reference, replace pronouns or phrases such as this concern with their full referents. For vocabulary, use context, contrast and non-examples to establish boundaries.
Summary and language repair
Separate summary selection from compression. First decide what belongs to the requested scope; then merge overlap; then paraphrase without changing quantity, certainty or cause. For grammar, reduce complex sentences to their main relationships before restoring descriptive material. For editing, include correct sentences so “no change” remains a real decision.
Writing repair
Correcting a sentence is not the same as repairing a writer. Start with purpose, paragraph job and logic. In argument, require a mechanism between claim and example, then ask what the example actually proves. In narrative, reduce the story to goal, obstacle, decision and consequence; add believable cost before spectacle.
Performance repair
Compare untimed and timed performance. If accuracy falls only under pressure, investigate where time disappears: rereading, over-planning, repeated rewriting, indecision or checking without a target. Teach recovery from residual uncertainty: make the best evidence-based decision available, mark the item, continue and return if time remains.
Transfer is the real test
Immediate correction is not transfer. Change topic, names, order, mode or distractors. Then delay the retest and finally mix the repaired skill among secure work without announcing the strategy. Record modelled, prompted, independent, mixed-transfer and delayed-transfer success separately.
Retire dedicated practice when the learner can use the decision independently in unfamiliar mixed work and retain it after a delay. A diagnostic system improves by becoming more selective.
