Why Research Philosophy Matters
Before choosing a research method, a researcher makes assumptions about reality, knowledge and how claims can be justified. These assumptions form part of a research paradigm.
Positivism
Emphasises systematic observation, measurement, regularities and empirical testing of explanations.
Post-positivism
Retains empirical investigation but recognises that observations and conclusions are fallible, theory-influenced and open to revision.
In practice, both traditions have internal diversity; they should not be reduced to rigid lists of research methods.
Ontology, Epistemology and Methodology
Ontology — What exists?
Assumptions about the nature of reality: for example, whether educational achievement can be studied as a reality existing independently of any particular observer.
Epistemology — How do we know?
Assumptions about what counts as knowledge and how claims can be justified through observation, reasoning and criticism.
Methodology — How should we investigate?
The rationale and overall logic of inquiry, including decisions about designs, measurement, sampling and analysis.
Methods — What techniques do we use?
Specific tools such as experiments, questionnaires, observations, interviews or statistical models.
Origins of Positivism
Auguste Comte (1798–1857) is widely associated with the formulation of positivism as a philosophy emphasising knowledge grounded in observation and scientific inquiry.
Comte’s law of three stages
Comte developed this account in his Course of Positive Philosophy (1830–1842).
Core Assumptions of Positivism
- Scientific inquiry should be guided by observable evidence and systematic reasoning.
- Phenomena can be studied to identify regularities, relationships and possible explanatory laws.
- Researchers should strive to minimise personal bias through clear procedures.
- Hypotheses and theories should be evaluated against evidence.
- Measurement, comparison and replication can strengthen confidence in findings.
Positivism has multiple historical forms. The stronger claim that all meaningful statements must be directly verifiable is particularly associated with logical positivism, not every form of positivism.
Classical vs Logical Positivism
Classical positivism
Associated with Comte; promotes scientific understanding of natural and social phenomena through observation and identification of regularities.
Logical positivism
Associated with the Vienna Circle in the early twentieth century; emphasised logical analysis and empirical criteria for meaningful scientific statements.
The verification principle
In influential logical-positivist formulations, a statement’s cognitive meaningfulness was linked to its analytic status or empirical verifiability.
Positivism in Educational Research
Illustrative research question
Does a scheduled retrieval-practice programme improve science test performance?
Possible approach
- Define the learning outcome and the intervention clearly.
- Use a suitable, consistently administered assessment.
- Collect data under planned conditions.
- Analyse the results using appropriate statistical procedures.
- Report the findings, uncertainty and limitations.
These methods are compatible with positivist assumptions, but the use of statistics alone does not establish that a study follows positivism.
Critiques of Strong Positivist Claims
- Theory-laden observation: Researchers interpret observations through concepts, assumptions and prior knowledge.
- Measurement limitations: Instruments may not capture every aspect of a complex phenomenon.
- Social complexity: Human behaviour can be shaped by context, meaning and changing circumstances.
- Induction problem: A finite set of observations cannot logically guarantee a universal law.
- Value and ethics: Research questions and interpretations may involve choices that require ethical reflection.
Meaning of Post-Positivism
Post-positivism is a broad family of approaches that takes scientific investigation seriously while rejecting the idea that researchers can obtain perfectly certain, completely theory-free knowledge.
Central principles
- A reality may exist independently of our beliefs about it.
- Our knowledge of that reality remains incomplete and fallible.
- Observations and measurements can be affected by assumptions and error.
- Claims should be critically tested against evidence.
- Conclusions remain provisional and may be revised when better evidence emerges.
Karl Popper and Falsifiability
Karl Popper (1902–1994) argued that scientific theories should be open to potential refutation. A theory gains scientific standing by exposing itself to tests that could show it to be mistaken.
Falsifiability
A claim is falsifiable if some conceivable observation or result could count against it.
Falsifiable example
Under specified conditions, students receiving a particular intervention will score higher on a defined test than comparable students who do not receive it.
Not readily falsifiable as stated
“The intervention improves learning in an invisible way whenever results appear negative.” The claim is framed to evade counterevidence.
Popper’s influential work includes The Logic of Scientific Discovery.
Verification vs Falsification
| Issue | Verification-oriented view | Popper’s falsification emphasis |
|---|---|---|
| Central question | What evidence supports or verifies a claim? | What evidence could show the claim to be wrong? |
| Scientific testing | Seek confirming evidence. | Expose theories to demanding tests. |
| Positive result | May be treated as confirmation, depending on the framework. | May corroborate a theory, but does not prove it permanently true. |
| Negative result | May challenge a proposed claim. | May refute a prediction, though measurement and auxiliary assumptions must also be considered. |
Critical Realism and Post-Positivism
Many textbook descriptions of post-positivism use the phrase critical realism: reality is understood as existing independently of researchers, while knowledge of it is always imperfect.
Critical realism as a distinct tradition
Critical realism is also the name of a developed philosophical tradition associated particularly with Roy Bhaskar. It should not simply be treated as another name for every form of post-positivism.
Realism
Reality is not reduced entirely to what an individual thinks or observes.
Fallibility
Researchers’ accounts of reality may be incomplete, mistaken or affected by assumptions.
Critical inquiry
Claims are examined through evidence, reasoning, criticism and comparison with alternatives.
Fallibilism and Probabilistic Knowledge
Fallibilism
Even well-supported scientific claims can be mistaken. Research knowledge should therefore remain open to review and correction.
Probabilistic reasoning
Research findings often support conclusions to a degree rather than providing absolute certainty. Statistical estimates, confidence intervals and uncertainty assessments can help communicate this limitation.
Reflexivity and researcher bias
Researchers should consider how their assumptions, expectations, instruments and decisions might affect data collection and interpretation.
Post-Positivism in Practice
Research question
Does formative feedback improve student learning, and how confident can we be that the observed effect is attributable to feedback?
A post-positivist workflow
- State a clear research question and testable expectations.
- Choose an appropriate design and define the variables.
- Use valid measures and consider measurement error.
- Look for alternative explanations and possible confounders.
- Analyse the evidence and report uncertainty.
- Invite critical scrutiny and revise conclusions when necessary.
Positivism vs Post-Positivism
| Dimension | Positivism (common textbook emphasis) | Post-positivism |
|---|---|---|
| Reality | Often assumes an objective reality that can be investigated scientifically. | Generally retains realism but recognises limits in knowing reality. |
| Knowledge | Emphasises systematic observation, measurement and scientific explanation. | Knowledge is fallible, provisional and subject to revision. |
| Researcher | Seeks objectivity and distance from the object of study. | Seeks objectivity while acknowledging potential bias and theory influence. |
| Evidence | Observation and empirical testing are central. | Evidence is central, alongside critical testing and alternative explanations. |
| Theories | May aim to identify regularities or laws. | Theories remain open to criticism, testing and revision. |
| Conclusion | Depends on the particular positivist tradition. | Normally qualified by uncertainty and study limitations. |
Post-Positivism Is Not Interpretivism
Post-positivism
Typically examines a reality not reducible to personal beliefs, while recognising that knowledge of it is imperfect and theory-influenced.
Example: Testing a hypothesis about learning outcomes while accounting for uncertainty and confounding factors.
Interpretivism
Emphasises understanding the meanings people give to actions and experiences within social and cultural contexts.
Example: Exploring how students understand belonging and exclusion in a classroom.
Constructivism
Often examines how people construct meanings and understandings through experience, interaction and context.
Example: Studying how teachers and students develop shared interpretations of classroom rules.
One Educational Problem, Different Questions
Problem: Students participate less frequently in classroom discussions.
Positivist-oriented question
Is there a measurable relationship between structured discussion activities and participation frequency?
Post-positivist question
Does a structured discussion intervention change participation, and what alternative explanations or measurement limitations must be considered?
Interpretivist question
How do students understand classroom discussion, and what meanings or experiences shape their willingness to speak?
Constructivist question
How do students and teachers jointly develop expectations about speaking, listening and participation?
Objectivity, Validity and Triangulation
Objectivity as an aim
Make claims open to scrutiny, use transparent procedures and reduce avoidable bias.
Validity
Assess whether the evidence supports the intended interpretation and whether alternative explanations remain plausible.
Reliability
Examine the consistency of measurements or procedures under comparable conditions.
Triangulation
Use multiple sources, methods, investigators or theoretical perspectives to examine a question from different angles.
Five Common Misconceptions
- “Post-positivism rejects objective reality.” Not generally; many versions retain a realist assumption while acknowledging limits to knowledge.
- “Every quantitative study is positivist.” Incorrect. Methods alone do not determine a paradigm.
- “Falsifiable means false.” Incorrect. A falsifiable claim could be contradicted by possible evidence.
- “A successful test proves a theory forever.” Incorrect. Evidence can support a claim without making it permanently certain.
- “Post-positivism and interpretivism mean the same thing.” Incorrect. They commonly differ in their assumptions about reality, knowledge and inquiry.
