In our previous blog on vocabulary, we explored why vocabulary sits at the heart of reading comprehension, curriculum access and academic success. We considered how differences in pupils’ word knowledge can quickly become differences in opportunity, and why explicit, intentional vocabulary instruction is a matter of equity as much as attainment.
For busy teachers a question that often follows such discussions is ‘But what does this actually look like in classrooms?’
This blog shifts from theory to practice. Drawing on the EEF’s “Vocabulary in action classroom strategies for vocabulary and language (adapted from Beck & McKeown, 2013), we explore six practical strategies from Vocabulary in Action and what they can look like in KS2 and mixed-age classrooms. Together, these strategies will help teachers move from simply introducing new words to building deep, durable word knowledge that pupils can use independently.
Why “Robust” Vocabulary Instruction?
Not all vocabulary teaching is equal. Copying definitions, matching words to meanings, or highlighting unfamiliar words in a text may increase exposure, but often does little to secure understanding or long-term retention. Research suggests that pupils learn words best when they meet them in meaningful contexts and are required to think hard about their meanings and how to use them.
Robust vocabulary instruction is therefore less about how many words we teach, and more about how deeply pupils come to know them.
1. Bespoke Definitions: Explaining Words in Everyday Language
Rather than relying on dictionary definitions, teachers introduce new words through explanations in connected, everyday language.
In a Year 3/4 mixed-age class encountering the word reluctant, a dictionary definition might say: Reluctant: unwilling or hesitant.
A bespoke definition might sound like: “Reluctant is when you don’t really want to do something, even though you know you probably should – like when you’re reluctant to step out of your comfort zone and try a harder maths challenge.
This anchors the word in a familiar experience and models how it works in real speech. For pupils with limited vocabulary, this is often far more powerful than a formal definition.
2. Purposeful Variation: Using Words Across Contexts
Pupils rarely learn a word fully from a single encounter. They need to meet it in varied, purposeful contexts that refine and extend its meaning.
In a Year 6 class learning the word significant, a teacher might use it:
● In history: “A significant moment in Shackleton’s journey was the open-boat voyage to seek rescue.”
● In maths: “That’s a significant change in the total”
● In discussion: “Why is this moment significant for the character?”
Across these examples, pupils begin to see that significant relates not just to “important”, but to importance with consequences.
3. Immediate Interaction: Thinking About Words Straight Away
New words should not be used only by teachers. Pupils need early opportunities to interact with meanings, however briefly.
In a history lesson introducing heptarchy, a teacher might ask: “What does the suffix ‑archy mean? What about the prefix hept-? Talk to your partner.”
These short partner-talks require pupils to process meaning, encourage oral rehearsal, and allow misconceptions to surface early. Small, frequent interactions are often enough to help new words begin to stick.
4. Deep Processing: Thinking Hard About Meaning Alongside brief interactions, pupils also need opportunities for deeper processing
Examples include: ● Sorting examples and non-examples ● Choosing the best word for a sentence and justifying why ● Explaining why a word does not fit
In a Year 6 writing lesson, pupils might be asked “Which word best describes this character – brave, reckless or confident? Which one doesn’t fit, and why?”
Here, pupils are comparing related concepts and articulating fine distinctions. This kind of demanding thinking is central to long-term retention.
5. Active Interest: Creating Discussion Around Words
Vocabulary teaching is most powerful when it sparks curiosity and discussion.
A Y3/4 teacher might ask “Which word better describes this setting: gloomy or mysterious?”
In primary classrooms, these prompts allow younger pupils to contribute orally while older pupils refine and extend their thinking. Vocabulary becomes something to explore and play with, not simply something to memorise.
6. Repetition, Repetition, Repetition: Planning for Revisiting
Perhaps the most overlooked aspect of vocabulary instruction is systematic revisiting. Most pupils do not learn a word securely after one or two encounters. They need multiple exposures across lessons, subjects and time.
In practice, this might include: ● Revisiting last week’s words in a starter ● Deliberately reusing target vocabulary in explanations ● Including words in retrieval quizzes ● Noticing and celebrating independent use
Repetition is most effective when it is planned, varied and embedded in everyday teaching.
A Final Thought:
Start Small, Build Consistency
Improving vocabulary instruction does not require a huge curriculum reform. Small changes in how we explain, revisit and discuss words can make a significant difference, particularly for disadvantaged pupils. A question to ask ourselves is “What small changes could I make in how I explain, revisit and discuss words in my everyday teaching that would make a real difference for the pupils who need it most?”
