Peer review is an editorial and expert assessment process, not a guarantee that a published claim is true. Students should understand the difference between a preprint, peer-reviewed paper, correction and retraction.
This is a practical guide for Punggol families from Primary Science through secondary, JC, diploma and university study. The Singapore national curriculum and each university’s current programme rules govern formal assessment, eligibility and supervised research.
What peer review actually examines
Reviewers may evaluate study design, reporting, novelty, analysis and fit for a journal. Review processes differ, and publication cannot replace independent replication.
A useful teaching check asks the learner to name the observation, select the relevant model, show the calculation or reasoning, and state one meaningful limitation. The teacher should correct the first mistaken assumption and then test the same principle using a different example without prompts.
Why corrections matter
An error in a table, unit or figure may be corrected transparently. Whether conclusions change depends on the error’s role in the analysis.
A useful teaching check asks the learner to name the observation, select the relevant model, show the calculation or reasoning, and state one meaningful limitation. The teacher should correct the first mistaken assumption and then test the same principle using a different example without prompts.
What a retraction signals
A retraction warns readers that a paper should not be relied on in the same way. Reasons vary and do not automatically prove intentional misconduct.
A useful teaching check asks the learner to name the observation, select the relevant model, show the calculation or reasoning, and state one meaningful limitation. The teacher should correct the first mistaken assumption and then test the same principle using a different example without prompts.
How to check a cited study
Verify authors, journal, date, DOI, methods and any editorial notices. AI-generated references should be checked against real sources.

The school-to-university pathway
Primary learners separate observation and inference; secondary learners assess controls; JC and university learners interpret uncertainty and research literature.

Worked example
A hypothetical report states 0.50 mol/L but a documented original instrument record supports 0.050 mol/L. The correction is tenfold, and the scientific impact must be evaluated rather than silently editing the published record.

Four-stage learning progression
Primary: recognise and describe evidence. Secondary: control variables and read measurements. JC or diploma: calculate, model and explain uncertainty. University: assess published methods, specialist evidence and the ethical limits of an actual project.
Frequently asked questions
Does this guarantee a university place? No. Academic admission and research selection follow the institution’s requirements.
Can a pupil use simulated results? Yes, if explicitly labelled hypothetical and not presented as actual measurements.
How is improvement assessed? By explaining a new problem independently, rather than copying a worked solution.
