Action research

A research approach in which researchers and practitioners work together to investigate a practical problem and develop solutions through iterative cycles of planning, action, observation and reflection.

Examples

Worked examples

  • Is an instance

    A teacher-researcher conducts an action-research cycle to test a new feedback practice in their classroom.

  • Is an instance

    A community organisation and university partner conduct PAR cycles to improve a service iteratively.

Counter-examples

Looks similar, but isn't

  • Not an instance

    A single-cycle pilot study labelled 'action research' without iterative learning cycles.

  • Not an instance

    Action research framing without practitioner co-investigators or shared reflection.

Editorial commentary

Action research traces to Kurt Lewin’s work in the 1940s and has developed multiple traditions: technical action research (focused on improving practice), practical action research (involving practitioner reflection), and emancipatory or critical action research (focused on social transformation). It is widely used in education (teacher inquiry), nursing, organisational development, and community development. Action research emphasises iterative cycles, participation of stakeholders as co-researchers, and integration of theory and practice. It overlaps with participatory action research (PAR), which emphasises power-sharing more strongly.

The cycle structure

Most accounts of action research describe a recurring cycle rather than a single linear study: plan, act, observe, reflect, then re-plan based on what the previous cycle revealed. A project may run several such cycles over its funded period, with each cycle’s findings feeding directly into the design of the next intervention. This is the feature that most distinguishes action research from a conventional applied study: the research design is expected to change as the project learns, rather than being fixed at the proposal stage and executed unchanged.

Why this matters for research administration

Action research’s iterative, stakeholder-driven design creates specific administrative and ethics-review considerations that a conventional fixed-protocol study does not:

  • Ethics review and protocol amendments: because the intervention itself may change between cycles in response to what participants and practitioners learn, an IRB or REC reviewing an action-research protocol often needs to approve a general iterative framework plus a lighter-weight amendment pathway for cycle-to-cycle adjustments, rather than reviewing each change as a full protocol resubmission.
  • Co-investigator and community-partner roles: where practitioners or community members function as co-researchers rather than only as subjects, institutions need to decide how those roles are documented (authorship, compensation, data access) and whether the co-researchers themselves require training or oversight typically reserved for study personnel.
  • Funder framing: funders that support participatory or community-engaged research (a category several public and philanthropic funders now name explicitly in solicitations) often ask proposals to describe the cycle structure and stakeholder-participation plan directly, rather than accepting a conventional methods section written for a fixed-design study.

Distinguishing action research from adjacent approaches

Action research is frequently confused with, or loosely equated to, several related but distinct approaches:

  • Participatory action research (PAR) is a strand of action research that specifically foregrounds shared power between researchers and community co-researchers in setting the research question, not only in executing it.
  • Community-based participatory research (CBPR) is closely related to PAR, with a stronger tradition in public-health and clinical research and an explicit emphasis on equitable partnership throughout the research process.
  • Implementation science shares action research’s applied, iterative orientation but is typically organised around formal implementation frameworks and outcome measures (adoption, fidelity, sustainability) rather than around researcher-practitioner cycles of reflection.
  • Translational research is a broader category concerned with moving findings from bench to practice across any methodology, of which action research is one possible design choice, not a synonym.

Frequently asked questions

Is action research qualitative or quantitative?

Either, or both. Action research is defined by its iterative, practitioner-involved cycle structure, not by a specific data-collection method; a cycle can use surveys, interviews, administrative data, or a mixture, depending on the practical problem being addressed.

Does action research require IRB or REC approval?

In most jurisdictions, yes, if it involves human participants and meets the local definition of research (as opposed to internal quality-improvement activity that some institutions exempt). Because the design is iterative, institutions commonly review it under a protocol structure that anticipates and streamlines cycle-to-cycle amendments rather than treating each cycle as an entirely new study.

How is action research different from a case study?

A case study is an in-depth examination of one or a small number of instances, typically without the researcher intervening in the setting. Action research specifically involves the researcher (often jointly with practitioners) deliberately intervening and then studying the effect of that intervention, repeated across cycles.
