Halpern's Framework for Critical Thinking

A teacher can be a careful thinker about argument analysis and a careless thinker about probability. The two are different skills. Diane Halpern’s framework takes this seriously and breaks critical thinking into domains, each with its own techniques. Treating critical thinking as a single general skill, in this view, hides the fact that someone can be sharp in one domain and weak in another.

What Halpern proposed

Halpern proposed a framework based on different kinds of critical thinking. Each kind covers a domain of thinking that benefits from its own set of techniques.

The domains are:

1. Thinking and language
2. Argument analysis
3. Hypothesis testing
4. Dealing with probability and uncertainty
5. Decision-making
6. Problem-solving
7. Creative thinking
8. Memory skills

(Some accounts of Halpern’s framework treat memory skills as a supporting domain rather than as a domain of critical thinking in its own right.)

Thinking and language

This domain covers how language shapes thinking. Specific techniques include:

1. Recognising persuasive language. Words that carry emotional charge (“crisis”, “obvious”, “everyone knows”) can shape a reader’s response without arguing for it.
2. Misuse of definitions. A word defined one way in one context and another in another can support contradictory conclusions if the shift goes unnoticed.
3. Leading questions. A question phrased to suggest its answer is not a question; it is a guided conclusion.
4. Paraphrasing. Restating a claim in different words to test whether the original was clear.
5. Using multiple representations. Examining a claim in different forms (verbal, written, visual) to test whether it holds across them.

A teacher who reads a textbook critically uses these techniques without naming them. Naming them sharpens the use.

Argument analysis

This domain covers the structure and quality of arguments.

1. Identifying premises, counter-arguments, and conclusions. What is being claimed, what supports it, and what argues against it.
2. Judging credibility. Who is making the claim, what is their evidence, what is their interest in the conclusion.
3. Difference between opinion, judgement, and fact. Each has a different status and requires different evaluation.
4. Avoiding common fallacies. A specific list of recurring reasoning errors.

A teacher who can identify a premise from a conclusion can teach students to do the same. A teacher who cannot tends to teach a flatter version of argumentation.

Hypothesis testing

This domain covers the empirical side of thinking.

1. Predicting and confirming hypotheses. What would the world look like if the hypothesis were true.
2. Operational definitions. Defining a term precisely enough to be measured.
3. Controlling variables. Holding other factors constant when testing one.
4. Sampling and generalisations. Whether the cases examined are typical of the wider group.
5. Limits of correlational reasoning. Two things changing together does not prove one causes the other.

This domain matters in education because much of the research teachers read involves these issues. A teacher who can tell a strong study from a weak one reads the literature differently from one who cannot.

Dealing with probability and uncertainty

This domain covers reasoning under conditions of incomplete information.

1. Estimating probabilities. Working out roughly how likely something is.
2. Risk assessments. Weighing the chance of an outcome against its severity.
3. Using baseline data. Knowing the base rate before evaluating a specific case.

A teacher reading that a particular method “improves outcomes” needs to ask, improves over what baseline? A teacher hearing that a particular intervention “rarely fails” needs to ask, rarely compared to what?

Decision-making

This domain covers how to make a choice well.

1. Framing a decision. Defining what is actually being decided.
2. Generating options. Going beyond the first two that come to mind.
3. Predicting consequences. Following each option out.
4. Weighing pros and cons. Honest accounting of each option’s costs.
5. Recognising bias. Noticing one’s own preferences and how they shape the analysis.

A teacher faces decisions constantly: which student to call on, which textbook to use, which complaint to address first. The same decision-making skills apply.

Problem-solving

This domain covers a specific class of decision: choosing a response to a defined problem.

The skills are similar to decision-making but with an emphasis on the structure of the problem itself: defining what the problem is, distinguishing the symptom from the cause, choosing a method that fits the kind of problem.

Creative thinking

This domain covers idea generation.

1. Redefining a problem. Stating it in a new way to open up options.
2. Generating possibilities. Producing many options before evaluating.
3. Seeing multiple perspectives. Looking at the problem from different angles.
4. Taking risks. Trying ideas that may fail.

Creative thinking sits inside critical thinking, in Halpern’s framework. The two are not opposed. Creative generation produces options; critical evaluation chooses among them.

Flashcard

Why does Halpern treat critical thinking as several distinct domains rather than one general skill?

Tap to reveal

Answer

Because someone can be sharp in one domain and weak in another

Argument analysis, hypothesis testing, probability reasoning, and decision-making each have their own techniques and their own typical failures. A thinker who is good at spotting fallacies may still be poor at understanding probability. Treating them as separate domains lets each one be developed deliberately. Treating them as one general skill hides the gaps.

Using Halpern’s framework

The framework’s strength is also its size. Eight domains, each with its own techniques, is more than a teacher can hold in mind at once. Practical use takes a few forms.

Self-audit

A teacher can read the domains and ask which she is comfortable with and which she is not. The uncomfortable ones are the next areas to work on.

Curriculum design

When designing a course on critical thinking, the framework helps to make sure the course covers the range of domains rather than focusing on one or two.

Diagnosing student difficulty

A student who struggles with a particular kind of question may have a gap in a specific Halpern domain. Naming the domain makes the gap addressable.

Reading research

When evaluating a published study, the framework helps to ask which kinds of critical thinking the study requires. A study heavy on statistics needs probability reasoning. A study based on argument needs argument analysis.

A teacher who gets familiar with the framework over a year tends to find her thinking about teaching itself becomes sharper, because she has the working vocabulary to name what kind of thinking is needed for which task.
