Health inquiry and action research for QCE Health Unit 3
“Apply the QCAA health inquiry process and the action research approach to investigate a community health priority and recommend evidence-based action”
The QCAA health inquiry process structures an investigation into a community health priority through stages of recognising and explaining, analysing and applying, and planning and evaluating. Action research adds a cyclical plan, act, observe and reflect loop that works with a community to build resilience as a community resource. Strong work uses high-authority evidence, weighs reliability and validity, triangulates sources, and treats inquiry as an iterative cycle. This process underpins the IA1 action research instrument.

What this dot point is asking
QCAA wants you to use the health inquiry process as your method for investigating a real community health priority and recommending action. Health is an inquiry-based subject, so the process is not background, it is the skill being assessed, especially in the IA1 action research. You need to know the stages, apply them in order, and justify your decisions with evidence. A strong response treats inquiry as a disciplined cycle with feedback, not a one-off report.
The answer
The health inquiry process
The QCAA health inquiry model gives you a structured way to investigate a priority issue. The stages are:
- Recognise and explain. Identify the priority health issue and explain why it matters using data and the determinants of health.
- Analyse and apply. Break the issue down, apply relevant frameworks (determinants, the Ottawa Charter, diffusion of innovations), and analyse the evidence to understand causes and protective factors.
- Plan and evaluate. Design action that is feasible and targeted, then evaluate its likely or actual effectiveness against criteria.
Each stage feeds the next, and you cycle back when new evidence changes your understanding.
Action research
Action research is a cyclical, participatory approach where you plan, act, observe and reflect, then refine and repeat. It is "research with" a community rather than "research on" it, which fits the salutogenic, strengths-based aim of building resilience as a community resource. The cycle has four phases:
- Plan. Identify the issue, set a question, and design an action strategy grounded in evidence.
- Act. Implement the strategy (or a model of it within the scope of school assessment).
- Observe. Gather data on what happened, using surveys, observation or existing population data.
- Reflect. Judge what worked, what did not, and what to change, then loop back into a refined plan.
The cyclical nature is the point: action research expects you to refine based on feedback rather than deliver a single fixed answer.
Evidence, reliability and validity
An inquiry is only as strong as its evidence. You weigh sources for currency, authority and bias. Population data from the Australian Institute of Health and Welfare or Queensland Health is high-authority; a single social-media post is not. You consider reliability (would the same method give the same result again) and validity (does the method actually measure what you claim). Triangulating several sources strengthens your conclusions and is rewarded in the criteria.
Action research is a cyclical approach of plan, act, observe and reflect, repeated to refine the strategy. It is participatory, working with a community rather than on it, which suits Unit 3's strengths-based goal of building resilience as a community resource.
Weighing sources for authority and bias
Not all evidence carries equal weight, and the criteria reward students who can justify their source choices. High-authority sources include the Australian Institute of Health and Welfare, Queensland Health, the World Health Organization and peer-reviewed research, because they are produced by expert bodies using rigorous methods and are regularly updated. Lower-authority sources, such as a single blog post, an opinion piece or an advocacy group with a vested interest, may be biased, out of date or unrepresentative. For each source, ask who produced it, when, why, and whether it has been checked. Currency matters because health data changes; authority matters because expertise and method affect accuracy; and bias matters because a source with a commercial or political stake may present a skewed picture. Documenting these judgements, rather than simply citing a source, is what lifts the evidence criterion.
Plan
Select a community health priority (for example low help-seeking for anxiety among Year 11 students), set a focused inquiry question, and design an evidence-based action strategy grounded in the determinants and the Ottawa Charter.
Act
Implement or model the strategy within the scope of the assessment, such as a peer-led wellbeing session and a promotion of a low-barrier service.
Observe
Gather data on what happened using a mix of methods (a pre and post survey, observation, and existing AIHW or school data), triangulating sources so the findings are not reliant on one measure.
Reflect and loop
Judge the strategy against clear criteria (reach, equity, sustainability), honestly identify limitations such as a small sample or self-report bias, and specify the refined plan for the next cycle, demonstrating the iterative nature the IA1 instrument assesses.
Connecting inquiry to assessment
The IA1 action research instrument assesses exactly this process. You select a priority issue, work through the inquiry stages, design and model an action strategy, and evaluate it through the action research cycle. The recommendations must be evidence-based and feasible, and your evaluation must use clear criteria. Examiners reward a clear question, justified method choices, triangulated evidence, and an evaluation that honestly identifies limitations and next steps in the cycle.
- Treating action research as a one-off report
- The cycle is plan, act, observe, reflect, then loop. Responses that never refine or revisit miss the defining feature.
- Weak or single-source evidence
- Conclusions built on one unverified source lose marks. Triangulate high-authority data and weigh reliability and validity.
- Vague or unfeasible action
- Recommendations must be specific, evidence-based and realistic within the community's resources, not aspirational slogans.
Exam-style questions
Questions in the style of QCAA exam questions on this dot point, each with a worked answer. They are written by ExamExplained unless tagged "Past paper"; the year shows the paper a question is modelled on.
Practice6 marksExplain the four phases of the action research cycle and justify why a cyclical approach is more appropriate than a one-off report for building community resilience.Show worked answer →
Six marks: the four phases described, then the justification.
The cycle (4 marks). Plan (identify the issue, set a question, design an evidence-based strategy); act (implement or model the strategy); observe (gather data through surveys, observation or population data); reflect (judge what worked and refine).
Why cyclical (2 marks). Community health issues are complex and conditions change, so refining the strategy based on feedback produces more effective, responsive action than a single fixed plan. The participatory, "research with" approach also builds the community's own capacity, fitting the salutogenic aim.
Markers reward all four phases plus a justification tied to responsiveness and community capacity.
Practice7 marksA student plans a health inquiry using only a single online article as evidence. Analyse the limitations of this approach and explain how triangulation, reliability and validity would strengthen the inquiry.Show worked answer →
Seven marks: the limitations, then the improvements.
- Limitations (3 marks)
- A single source may be biased, out of date or low-authority, so conclusions are weak and not defensible; there is no cross-check on accuracy.
- Triangulation (2 marks)
- Using several independent high-authority sources (AIHW, Queensland Health, peer-reviewed research) that agree strengthens confidence in the findings.
- Reliability and validity (2 marks)
- Reliability asks whether the same method would give the same result again; validity asks whether the method measures what it claims. Choosing methods that are both reliable and valid makes the evidence trustworthy.
Markers reward the named weaknesses of single-source evidence and a clear explanation of triangulation, reliability and validity.
