Primary and Secondary Research
Selecting research methods, interpreting user and product evidence, and recognising bias, validity and practical limitations.
How to prepare for the GCSE Design and Technology written exam
Move from requirement to evidence, technical principle, comparison and justified decision. Use current board materials separately for the NEA and for full timed-paper rehearsal.
Core concepts
Concept 1
Primary research creates new evidence for the project through methods such as interviews, observation, questionnaires or testing; secondary research uses existing evidence.
Exam cue: Name the design decision the research must support before choosing a method.
Concept 2
A method is chosen for the decision it must inform: observation can reveal behaviour, interviews can explore reasons, and product analysis can reveal existing solutions.
Exam cue: Separate what the data shows from the design inference drawn from it.
Concept 3
Evidence quality depends on relevant participants, fair questions, sufficient data, reliable measurement and acknowledgement of missing voices or constraints.
Exam cue: Suggest an improvement that addresses a specific weakness in sampling, wording or measurement.
Risk pitfalls and guardrails
Calling internet research primary because the learner collected it personally.
Guardrail: Do not substitute one board's specialist route or current product claim for the multi-board core, and do not turn written process knowledge into NEA or practical submission material.
Assuming a large response count automatically removes selection bias.
Guardrail: Do not substitute one board's specialist route or current product claim for the multi-board core, and do not turn written process knowledge into NEA or practical submission material.
Reporting a percentage without considering the sample or question wording.
Guardrail: Do not substitute one board's specialist route or current product claim for the multi-board core, and do not turn written process knowledge into NEA or practical submission material.
Memory anchors
Primary research
New evidence collected directly for a particular investigation.
Secondary research
Existing evidence created by another source or for another purpose.
Sample
The people, products or observations selected to provide data.
Bias
A systematic influence that makes evidence unrepresentative or unfair.
Evidence triangulation
Comparing different evidence sources to test whether a conclusion is supported.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
