Study Notes
Action Research: Data Collection Considerations
- Validity is crucial in action research, encompassing both external and internal aspects to ensure data integrity.
- External criticism involves evaluating the authenticity and genuineness of data before use, helping to eliminate false evidence and malpractice.
- Key elements of external criticism include:
- Clarification of the date an event occurred and when the source was written.
- Identification of the place where the data was produced.
- Determination of authorship to understand who created the documents.
- Analysis of pre-existing material that may have influenced the data's production.
- Verification of the integrity of the data's original form.
External Validity and Generalizability
- The robustness of findings across varying contexts enhances external validity; the more diverse the case study samples, the more generalizable the results.
- Three threats potentially affect generalizability:
- Interaction of selection and treatment can limit applicability across different demographic groups.
- Interaction of setting and treatment restricts generalization from the experimental setting to different environments.
- Interaction of history and treatment diminishes the ability to apply findings to future or past scenarios.
Internal Validity
- Internal validity gauges how confidently a causal relationship can be inferred between independent and dependent variables, with true experiments achieving higher internal validity through randomization and control.
- Internal criticism focuses on the accuracy of data post-authentication, assessing the credibility of the source content.
- Understanding credibility involves evaluating content for truthfulness and worth, leading to informed judgments on data accuracy.
- Key elements of internal criticism include:
- Historical events affecting subjects and data.
- Subject maturation, which may sway responses over time.
- Testing effects from participants becoming accustomed to the study.
- Instrument accuracy, ensuring standardized procedures are used.
- Subject selection methods, emphasizing the risks of nonrandom, biased samples.
- Mortality rates of participants dropping out of studies.
- Diffusion of treatment effects when control groups inadvertently receive treatment.
- Compensatory equalization, ensuring both groups receive equivalent treatment.
