# Wiersma Jurs Education Research Methods

> Design, communicate, and critically evaluate educational research using Wiersma and Jurs's Research Methods in Education: An Introduction, ninth edition. Use when formulating variables, operational definitions, questions, and hypotheses; reviewing literature; preparing or reviewing proposals and reports; choosing experimental, quasi-experimental, nonexperimental quantitative, qualitative, historical, ethnographic, mixed, modeling, or Delphi designs; or planning sampling, measurement, descriptive statistics, and inferential statistics. Emphasize control of variation, validity and reliability, design diagrams, and a transparent chain from problem to conclusion; update all ethics, technology, and statistical guidance beyond the 2008/2010 edition.

# Wiersma–Jurs Education Research Methods

Treat research as an empirical, systematic, valid, reliable, and plural process. Use the recurring chain:

`identify problem → review literature → collect evidence → analyze → conclude and communicate`

The chain is organized but not mechanically linear. Design-specific iterations are expected; quality depends on execution, not a hierarchy in which one method is automatically more scientific.

## Workflow

1. **Determine the problem.** Specify variables or qualitative phenomena, units, setting, population/case, operational definitions, and whether the study asks a question or tests a directional/nondirectional/null hypothesis. Read [chapters/ch01-problem-literature-and-communication.md](chapters/ch01-problem-literature-and-communication.md).
2. **Build the evidence base.** Search, select, critically read, organize, and synthesize literature; show how it sharpens the question and design.
3. **Choose the design family.** Use experiment for randomized causal contrasts; quasi-experiment where assignment is constrained; nonexperimental design for description, association, survey, or ex post facto questions; qualitative design for contextualized meaning/process; historical research for evidence about the past; ethnography for culture and natural settings. Read [ch02](chapters/ch02-quantitative-designs.md) and [ch03](chapters/ch03-qualitative-historical-ethnographic.md).
4. **Control variation and bias.** Increase systematic variation relevant to the question, control extraneous variation, and reduce error variation. Draw the design and list threats.
5. **Select cases or participants.** Distinguish random selection from random assignment; match probability or purposive sampling to inference. Read [chapters/ch05-sampling-measurement-statistics.md](chapters/ch05-sampling-measurement-statistics.md).
6. **Measure or document.** Define evidence, instrument/protocol, scoring/coding, reliability/credibility, validity, administration, and data management.
7. **Analyze proportionately.** Begin with distributions and descriptive summaries; use inferential procedures only when design and assumptions support them; use contextual coding and deep description for qualitative material.
8. **Combine or model only for a purpose.** Read [chapters/ch04-mixed-modeling-delphi.md](chapters/ch04-mixed-modeling-delphi.md).
9. **Communicate.** Prepare a proposal or report with problem, literature, method, results, conclusion, implications, limitations, references, and relevant appendices.
10. **Evaluate the report.** Examine alignment, omissions, error, credibility, scope, ethics, and whether conclusions exceed results.

## Required output

Provide problem and rationale; variables/phenomena and definitions; question/hypothesis; literature strategy and synthesis; design diagram; sample and assignment; data/measurement plan; threats to validity/reliability; analysis; ethics; reporting plan; and conclusion boundaries.

Use [patterns.md](patterns.md), [cheatsheet.md](cheatsheet.md), and [glossary.md](glossary.md).

## Guardrails

- Do not confuse random sampling with random assignment.
- Do not infer causation from ex post facto, correlational, or cross-sectional survey evidence.
- Do not call non-equivalent groups equivalent because their pretest means are similar.
- Do not interpret gain scores, repeated measures, single-case reversals, or time series without their design-specific assumptions.
- Do not treat reliability as validity, or validity as a permanent property detached from interpretation and use.
- Do not infer representativeness from response rate alone; analyze coverage and nonresponse.
- Do not use p-values without effect estimates, uncertainty, assumptions, and design context.
- Do not treat qualitative coding software as analysis or deep description as unbounded anecdote.
- Do not use Delphi consensus as truth; report panel selection, attrition, iteration, feedback, and disagreement.
- Follow current ethics review, safeguarding, privacy, data-security, statistical, and reporting standards.
