Core Ideas about Thinking Skills
Six core critical thinking skills
| Skill | What it does |
|---|---|
| Interpretation | Understand and communicate the meaning of information |
| Analysis | Connect pieces of information to determine their meaning |
| Inference | Identify what is needed to reach an accurate conclusion |
| Evaluation | Judge the credibility of statements and the validity of information |
| Explanation | Communicate ideas clearly to specific audiences |
| Self-regulation | Monitor one’s own thinking and adjust as needed |
In teaching
Each skill maps to a regular teaching task: reading student work, analysing classroom dynamics, drawing fair conclusions, evaluating evidence, explaining ideas, and noticing one’s own thinking.
A reflective practitioner who wants to think more clearly needs to know what the components of clear thinking are. Critical thinking is not a single skill. It is a set of related skills, each of which can be named, practised, and improved. Six core skills cover most of the ground.
The six core skills
The skills are interpretation, analysis, inference, evaluation, explanation, and self-regulation. Each one does specific work that the others do not do as well.
Interpretation
Interpretation is the ability to understand the information being presented and to communicate the meaning of that information to others.
A teacher faces interpretation tasks daily. Reading a student’s written response and working out what the student actually meant. Reading a colleague’s comment and understanding what they are saying. Reading a curriculum document and grasping what it requires.
Interpretation skills let the teacher decode information accurately and add clarity. The clearer the interpretation, the better the teacher can understand her students and respond to them. A teacher who misreads a student’s question or comment ends up answering a different question than the one being asked.
A short example. A student asks, “Why are we learning this?” Different interpretations:
- The student is bored and wants to be heard.
- The student is genuinely curious about the connection between the topic and other things they care about.
- The student is challenging the teacher’s authority.
- The student is asking for a more concrete example.
Each interpretation suggests a different response. A teacher who interprets accurately responds usefully.
Analysis
Analysis is the ability to connect pieces of information together to determine the intended meaning.
If interpretation is about understanding one piece of information, analysis is about making sense of how several pieces fit together. The teacher reads between the lines.
A worked example. A student’s recent assignments show a pattern: she scored well on the first two, dropped to a poor score on the third, and improved slightly on the fourth. Analysis connects these data points and asks what is going on. Was the third assignment harder? Did something change for the student between assignments? Is the dip a response to a specific topic, or to a wider pattern? Each connection produces a possible explanation that interpretation alone would not surface.
Inference
Inference is the ability to identify the elements needed to reach an accurate conclusion or hypothesis from the information available.
Inference asks a particular question: what additional information would I need to be confident in my conclusion? The teacher recognises both what she has and what is missing.
The skill matters because most situations in teaching do not present complete information. The teacher has fragments. Inference is the discipline of working with the fragments while staying alert to the gaps.
A teacher who concludes “the student is unmotivated” from a single missed assignment is making an inference with insufficient evidence. A teacher who notes “this student missed one assignment; I do not yet know why; I will check before drawing any conclusion” is exercising the inference skill carefully.
Evaluation
Evaluation is the ability to assess the credibility of statements and the validity of information being presented.
A teacher evaluates constantly. Student responses, colleagues’ opinions, the claims in a textbook, the recommendations of a training session. Some of what comes in is well-supported. Some is not. Evaluation is the discipline of distinguishing the two.
The skill matters when evaluating student responses. The teacher asks whether the information she is receiving is valid and whether it needs further checking. A confident-sounding answer is not the same as a correct answer. A hesitant answer is not the same as a wrong answer. Evaluation looks past the surface delivery to the substance underneath.
Explanation
Explanation is the ability to communicate ideas clearly, with attention to the audience.
A teacher’s explanation skill shapes whether her students understand the lesson. Two teachers can know the same content equally well, and the one who explains better produces more learning.
The skill is more than knowing the content. It includes:
- Choosing the right level of detail for the audience
- Picking examples that connect to what the audience already knows
- Using language the audience can follow
- Checking whether the explanation is being understood and adjusting if not
A teacher who explains a concept the same way to a first-year B.Ed. class as to a fellow expert is not exercising the explanation skill well. The skill includes the ability to vary the explanation by audience.
Self-regulation
Self-regulation is the ability to monitor one’s own thinking and adjust as needed.
This is the meta-skill. The other five skills can be applied without self-regulation, but they will be applied less well. Self-regulation lets the thinker notice when her own analysis is incomplete, when her interpretation might be biased, when her evaluation is letting fatigue or social pressure shape it.
For a reflective practitioner, self-regulation overlaps closely with the self-awareness that reflective practice models like Atkins and Murphy emphasise. The thinker watches her own thinking and corrects course when needed.
It governs the use of the other five core skills
Interpretation, analysis, inference, evaluation, and explanation can each be done without self-regulation, but the work tends to be weaker. Self-regulation lets the thinker notice when her interpretation is biased, when her evidence is incomplete, when her explanation is missing the audience. Without it, the other skills run unsupervised and produce errors that go uncorrected.
How the six skills work together
The six skills do not run in isolation. A typical reflective task uses several at once.
A teacher reading a student’s essay:
- Interprets what the student is trying to say
- Analyses how the parts of the essay connect
- Infers what the essay tells her about the student’s understanding
- Evaluates the credibility of the student’s reasoning
- Explains her response in a way the student can use
- Self-regulates by checking whether her own response is fair and accurate
The skill set is integrated. A teacher who is strong in interpretation and weak in self-regulation may still misread the situation, because her own biases are unmonitored. A teacher who is strong in self-regulation but weak in inference may notice her gaps without filling them.
The point of naming the skills separately is not to suggest they run separately. It is to make each one nameable, practisable, and improvable.
Building the skills
A teacher who wants to build these skills can work on them in three ways.
Practice in low-stakes settings
Reading a newspaper editorial with the six skills in mind. Watching a documentary and naming where each skill is being used or where one is missing.
Practice in teaching tasks
Reading student work with the six skills explicit. Marking an assignment and noticing which skills were used and which could have been used.
Practice through teaching the skills
Teaching the skills to students requires the teacher to use them with new clarity. The classroom itself becomes a place where the skills are sharpened.
A teacher who works on the skills over a year tends to find that her thinking gets more disciplined across all parts of her work, not only in critical thinking explicitly.
