CHAPTER 01 · Inquiry & Evidence: A Practical Guide

Start with a question

Key idea

A useful inquiry begins with a question narrow enough to answer and important enough to examine. Separate the topic from the question; specify population or setting, concept, comparison when relevant, and time. Then ask what evidence could change your mind.

Worked example

Example: “How do digital tools affect learning?” is broad. “What changes when a course adds weekly low-stakes practice, compared with the same course without it?” names an intervention and a comparison, while still leaving context and outcome to define.

Check your understanding

A question is not a hypothesis. A hypothesis is a, testable expectation; exploratory work may appropriately begin without one.

Self-check: Which part is observation, which is interpretation, and what evidence would change the conclusion?

Reasoning: Name the claim’s scope, supporting source and one limitation before deciding how far it travels.

Limit: A question is not a hypothesis. A hypothesis is a, testable expectation; exploratory work may appropriately begin without one.

CHAPTER 02 · Inquiry & Evidence: A Practical Guide

Choose a design that fits

Key idea

Descriptive, comparative, qualitative, experimental and mixed-method designs answer different questions. Choose the design after deciding what must be known. A design is a plan for producing evidence, not a badge of rigor by itself.

Worked example

If the aim is to understand how learners describe barriers, interviews may help. If the aim is to estimate a difference under specified conditions, a comparison design may help. Neither design automatically explains every cause.

Check your understanding

Do not infer causality from a simple before-and-after difference without examining alternative explanations.

CHAPTER 03 · Inquiry & Evidence: A Practical Guide

Define measures and concepts

Key idea

Operational definitions explain how an abstract idea becomes an observable indicator. A measure should match the concept, be understandable to its users, and include known limits. Record who provides the data, when, and under what conditions.

Worked example

For “participation,” possible indicators include attendance, submitted work, discussion contributions, or a learner’s own account. These are not interchangeable; each captures a different part of the concept.

Check your understanding

A numerical measure can look precise while representing a narrow or biased proxy.

CHAPTER 04 · Inquiry & Evidence: A Practical Guide

Read evidence in context

Key idea

Assess source purpose, method, population, comparison, uncertainty and limits. One study rarely settles a broad question. Look for convergence across methods and for meaningful disagreement, not only a headline result.

Worked example

A reported average difference should be read with the scale, spread, missing data, sample and comparison group. Ask whether the observed difference is meaningful in context, not only whether a threshold was crossed.

Check your understanding

An abstract or press release is not a substitute for checking the full methods and limitations when available.

Reasoning: Name the claim’s scope, supporting source and one limitation before deciding how far it travels.

Limit: An abstract or press release is not a substitute for checking the full methods and limitations when available.

CHAPTER 05 · Inquiry & Evidence: A Practical Guide

Make an interpretation traceable

Key idea

Separate observation from interpretation. Keep a claim-evidence-reasoning chain: state what was observed, cite its source, explain the inference, and label the uncertainty. List plausible alternatives.

Worked example

Observation: responses differed between two groups in this dataset. Interpretation: the groups may have experienced different conditions. Further evidence is required before attributing the difference to one cause.

Check your understanding

Do not turn association, an illustrative example, or a scenario into a verified institutional finding.

CHAPTER 06 · Inquiry & Evidence: A Practical Guide

Report limits and next steps

Key idea

A good conclusion states what the evidence supports, what remains uncertain, who or what was not represented, and what would be useful next. Share enough method detail for another reader to follow the reasoning.

Worked example

A small classroom exercise can reveal confusing instructions in that class. It cannot establish a universal effect for all learners. A next step might compare multiple settings using a transparent protocol.

Check your understanding

These learning notes are not a research protocol, ethics approval or formal review.
