EDUF4044 Chap.3 Finding and Reading Research Evidence
Finding and Reading Research Evidence
This chapter builds a transparent route from concepts and search terms to screened, appraised evidence. It distinguishes primary empirical research, reviews, theoretical work and policy material, then reads an empirical paper through its question, participants, method, analysis, findings and limitations.
Relevance, credibility and transfer are treated as separate judgements so a useful source can be included with an appropriately bounded interpretation.

Key terms
- Search string
- A documented combination of concepts, synonyms and operators used to retrieve sources.
- Primary research
- A study reporting original evidence produced through a stated design and analysis.
- Peer review
- Evaluation of scholarly work by relevant experts before publication.
- Transferability
- A reasoned judgement about how insight may apply beyond the original study context.
Finding and Reading Research Evidence FAQ
How do I know when to stop searching?
Stop when new searches mainly repeat established themes, key disagreements are represented and central studies have been followed through references and citations. Record the route so the stopping point is transparent rather than arbitrary.
Is a systematic review always better than a primary study?
They answer different needs. A review maps or synthesises a body of evidence, while a primary study exposes participants, context and original methods. Appraise both and use each for the claim it can support.
Can I reject every small qualitative study as weak?
No. Small samples may be appropriate for depth and meaning. The problem arises when conclusions generalise beyond the design or when the analytic trail is unclear. Judge fitness for the question rather than sample size alone.
Assessment move
Keep a search log with databases, terms, dates and filters. For every included source, write four sentences: why it is relevant, what supports its claim, what limits confidence and what it can inform in your context. Read the full paper when abstracts omit measurement, attrition or analytic detail, and verify every citation before it enters the review. Build the search in concept blocks.
Give each block several synonyms, spelling variants and disciplinary terms, then test combinations rather than writing one enormous query. Save useful subject headings from strong records because author vocabulary may differ from your initial wording. After the first search, sample both relevant and irrelevant results and diagnose why the query retrieved them. Add or remove terms for a reason and record the effect on coverage.
Screen titles and abstracts against written inclusion criteria, but retain a note when information is unclear so that uncertainty is not silently treated as exclusion. For close reading, use the empirical-paper template to record the research problem, prior literature, question, participants, design, evidence, analysis, findings and limitations.
Add your own judgement in a separate field so author claims are never confused with appraisal. Follow references backward from central studies and citations forward to replications and critiques. Compare publication date, context and methodological development rather than assuming newer means stronger. Once themes begin to repeat, search specifically for disagreement, negative findings and underrepresented contexts.
Finally, conduct a citation audit by opening every source used in the draft. Check that page details, digital identifiers and author names match the original, and confirm that each citation supports the exact nearby clause. Remove plausible but unverified references regardless of how well they fit the argument. Create a weekly appraisal comparison using two papers that address a similar topic through different methods.
Write what each design makes visible, what remains inaccessible and how the authors word their conclusions. Check whether the abstract is more confident than the discussion and whether limitations actually change the stated claim. Add one sentence on transfer to your setting without treating contextual similarity as proof.
Review the pair with a classmate and defend inclusion using relevance and credibility rather than journal reputation alone. This routine develops the judgement needed to select a compact evidence base for the literature review. At the end of each search session, save one strong source, one excluded source and the reason for each decision. Revisit those decisions after the question changes.
A source excluded for population mismatch may become useful for a mechanism claim, while a formerly central source may no longer answer the refined question. This keeps selection responsive without becoming arbitrary. Close by verifying one central citation from the original publication and restating exactly what its design can support.
