What if vocabulary instruction helped students make meaning in a subject rather than simply memorize definitions?
There are so many words students need to learn, and so many obstacles to teaching them well. As a teacher, I have found two challenges particularly difficult:
- Choosing which words to teach explicitly. How do we select words that strengthen content learning without taking valuable time away from the content itself? Students enter our classrooms with different vocabularies and prior knowledge, so not every student needs the same instruction. And with so many important words and so little time, vocabulary instruction can easily feel like an interruption to a lesson rather than an essential part of learning.
- Helping students retain and apply what they learn. Even after a great vocabulary lesson, students may forget the words or struggle to use them independently. Planning meaningful opportunities for students to revisit words while continuing to introduce new ones can feel overwhelming.
Vocabulary instruction is challenging, but I believe it is worth the time and effort it takes to get it right. Vocabulary knowledge plays an important role in reading comprehension and students’ ability to access and learn disciplinary content (Brabham et al., 2012).
As a former high school English teacher and current secondary reading interventionist, I have spent years experimenting with vocabulary instructional strategies and tools. Some were helpful; others felt like a waste of time. Too often, the strategies that looked promising on paper felt disconnected from my instruction, required too many steps, or demanded more planning and instructional time than I could sustainably give.
That changed when I learned about disciplinary literacy and began rethinking my overarching instructional goal.
My goal isn’t simply to teach students a list of words—or even to cover a list of learning objectives. My goal is to help students develop the knowledge and strategies they need to become independent learners and active participants in their academic disciplines.
Vocabulary instruction becomes much more powerful when we keep that goal in mind. Our job is to help bridge the gap between the knowledge, experiences, and language students bring to the classroom and the ways of thinking, communicating, and making meaning valued within the disciplines they are learning.
So, what does that look like in practice?
Strategic, Student- and Content-Centered Word Selection
Choosing the right words to teach, and knowing when to teach them, is challenging regardless of the instructional strategy we use. I love words and believe they all have something to offer, but I’ve learned that I can’t teach them all and still keep content learning at the center.
I’ve found that I get the most out of my vocabulary instruction when I prioritize words that students will encounter in an upcoming text, concept, or learning objective and that offer opportunities for connections beyond a single lesson. These words might include those with common roots and multiple meanings and are essential words for understanding instructional content.
The key is to select words that do more than help students get through a single lesson. Vocabulary instruction should be integrated within and across content areas, and it should be comprehensive (Blachowicz et al., 2006; Nagy & Townsend, 2012). We want students to recognize connections between the words they learn in class and the words they encounter elsewhere, gradually expanding their knowledge of language and their ability to learn new words independently.
My frustration with spending so much time on vocabulary without seeing a meaningful impact on students’ content learning began to ease when I gave myself permission to respond flexibly to student needs and let go of the expectation that I had to plan every learning experience in advance.
Now, I begin with the content I want students to learn. Vocabulary instruction supports that goal; it doesn’t compete with it.
At the beginning of a lesson, I typically introduce one to three words as a hook or gateway into the learning ahead. As we explore those words, students know to consider a bigger question: How do these words connect to the content we’re learning today?
Students make predictions about those connections, then revisit them at the end of the lesson to confirm or revise their thinking. Inferencing is an important skill in any field, but especially in reading and language learning (Blachowicz et al., 2006), and it’s a core skill students practice as part of my vocabulary instruction.
Words I preteach: These words are central to understanding the upcoming text or concept. They might come directly from the text, or they might be words that help students encapsulate the main idea or topic they’ll be learning about.
Of course, this is only a small part of vocabulary instruction. Much of the learning happens in context, and the words we address—and the time and strategies we use—depend on students’ needs.
That requires preparation, but it also requires flexibility. When previewing instructional materials, I try to put myself in my students’ shoes and anticipate which words or concepts might cause difficulty. I prepare possible ways to address those challenges, then adjust as I see what students actually know.
When we encounter an unfamiliar word, I ask students what they already know. If they understand it, we move on. If they don’t, I’m ready to help.
Words we discover in context: These include words that students find interesting and words I notice they are struggling to understand. As we encounter them, I teach them about the word and draw attention to previously taught words and roots that are relevant, helping students connect new learning to what they already know. Along with inferencing, building students’ morphological awareness and teaching students to think about words across contexts are two other central aspects of my vocabulary instruction. There is a significant correlation between morphological awareness and reading comprehension (Liu et al., 2024). Likewise, helping students create connections between words and contexts promotes the ability to think flexibility about words in order to generalize vocabulary and apply word knowledge in new contexts (Norman et al., 2023).
At first, letting go of rigid vocabulary routines made me anxious. I worried that students would study fewer words and miss opportunities for deeper word study. But I’ve found that when vocabulary instruction is grounded in content learning and responds to students’ needs, my students largely retain vocabulary learning and apply practiced vocabulary strategies independently.
My students don’t complain about vocabulary anymore. More often than not, they’re excited to share connections between words with common roots and words they’ve encountered in other classes.
For my students and me, vocabulary has become a tool for understanding content rather than a disruption to it.
Keeping Vocabulary Visible & In-Use
We’ve all heard about the importance of repeated encounters with words. Research explores how often students need to encounter a word, the kinds of encounters that support learning, and the intervals at which those encounters should occur (Uchihara et al., 2019; Nakata & Elgort, 2021). We also know that understanding a word isn’t an all-or-nothing proposition. A student might recognize a word without being able to define it, understand a word’s meaning without knowing how to use it appropriately, or recognize a familiar word in one context without understanding its meaning in another (Monster et al., 2021).
These are important considerations, but I found myself making vocabulary instruction unnecessarily complicated as I tried to plan and manufacture every encounter with every word. I felt as though I was failing my students whenever I couldn’t keep up.
When I refocused on content learning and meeting students where they were, I realized that many of these encounters began to happen naturally. I just needed to recognize and take advantage of them.
By selecting fewer, more purposeful words and letting student needs guide the rest of our word study, I’ve made vocabulary instruction more manageable. Words reappear naturally throughout lessons and across units. I make a point of highlighting them in texts, using them in my own speech, and encouraging students to use them in theirs. Keeping previously taught words visible in the classroom also reminds us to notice and revisit them.
Opportunities to retrieve words, elaborate on their meanings, and connect them to new contexts can help strengthen word knowledge (Rice & Tokowicz, 2020). This more flexible approach has helped me create these opportunities for students without having to engineer every interaction. It has also made word study more enjoyable and encouraged students to become curious about language.
Rather than treating vocabulary as a separate task to complete, we make it part of how we learn, talk, read, and think.
Classroom Example: An Expedition for Meaning
This week, my students read a short text of about 600 words titled Lewis and Clark Go West. The lesson had three goals:
- Use knowledge of social studies values and goals to analyze the genre and structure of a social science text.
- Practice identifying main idea.
- Build background knowledge about a topic students are studying in their history course.
Here’s how vocabulary instruction fits into that lesson.
Vocabulary Pre-Teach: Expedition
I chose expedition because it appears several times in the text, captures an important idea, and offers opportunities to explore word parts, morphology, and how knowledge of roots can help us learn unfamiliar words.
I began by writing the word on the whiteboard. Students copied it into their vocabulary notes using a graphic organizer I had provided.
Then I asked them to look closely at the word. Could they identify any familiar words or word parts?
They identified ex- and -ion, and we discussed their meanings and explored other words containing those elements. I then introduced ped-/pod-, a root associated with the foot, and students considered how that connection might help us think about the meaning of expedition. We discussed how word parts can provide clues to meaning without always giving us the complete definition.
Next, I shared the definition of expedition and gave examples of the word in use. The students then wrote their own example sentences using the newly learned word.
Before moving on, I gave them the opportunity to practice using their new understanding of the vocabulary word and its roots by exploring the word expedite. Students identified familiar word parts and used them to make an initial inference about the word’s meaning. After I shared the definition—to speed up a process—they compared the definition with their predictions and discussed the connection.
With our word study complete, we turned to the bigger question: How might expedition connect to our learning objective or today’s text?
Our learning objective was: “We will analyze the genre and structure of a social science text so that I can make inferences about the purpose of the text and identify the main idea.”
Some students suggested that we were going on an expedition to learn more about social studies or to discover how to identify a main idea. Others noticed the title of the text and used their background knowledge of Lewis and Clark to infer that the word referred to their journey.
Students had made an initial prediction, and they now had a reason to pay attention to how the word connected to the content.
This has become a familiar routine in my classroom, so students know what to expect. The entire activity took about 10 minutes.
Vocabulary In-Context: Responding to Student Needs
Before the lesson, I anticipated that students might struggle with the words intrepid, keelboat, adequate, and impede in the text.
For intrepid, adequate, and impede, I considered how students might break down the words, which familiar word parts might help them, what context clues were available, and where they might encounter the words again. I was especially excited that impede offered an opportunity to revisit a word part we’d discussed during our study of expedition.
Because keelboat was a specialized term that wasn’t central to the lesson’s learning goals, I planned to explain it briefly in context and point out the clues in the text that helped establish its meaning.
I was correct in my assumption that students would struggle with those words, and I taught them as planned. However, when we encountered adequate, and I paused to ask students what it meant, students demonstrated that they already understood the word, so we moved on.
This is an important part of responsive instruction: I can prepare to teach a word without assuming that I need to teach it. The goal isn’t to teach every word students might encounter. It’s to identify the words that might interfere with learning and determine what support students actually need.
As we moved through the text, other words and phrases needed attention, including confirmation, catalogued, and blind-devotion.
Several students seemed unsure about confirmation, so rather than immediately giving them the definition, I used a few questions to help them draw on what they already knew.
Me: “What other word does this look like?”
Students: “Confirm.” “Firm.” “Does it use com-?”
Me: “Yes!” “What does con-, com-, col-, cor-, co– mean?”
Students: “Together!”
Me: “Yes! What does it mean if something is described as firm?”
Students: “To be hard.” “To be strong.” “Like, solid.”
Me: “Right. So, remind me, what does it mean when you confirm something to be true?”
Students: “You give evidence to make something more legit.”
Me: “Exactly. And confirmation is a noun representing that act.”
Students: “So confirmation means proving something is real?”
Me: “You got it! It’s the act of proving that an idea or statement is true. One last question, why does the author write that this was a ‘voyage of confirmation’?”
Students: (looking at the text) “Um, because they had to see if what other people said before was true.”
Me: “So they had to…what?”
Students: “Confirm it.”
This conversation took less than a minute, but it gave students an opportunity to connect familiar language to a new word and use the text to deepen their understanding. Rather than supplying the definition immediately, I used questions to help students activate prior knowledge, examine meaningful word parts, and test their developing understanding against the context. My questioning also helped scaffold understanding of the word, which helped prevent students from giving an inaccurate definition of the word that could create misunderstanding of the word among their peers.
If students hadn’t already learned about the con-/com- word family, I could have simply explained the meaning and asked them for a few examples of other words containing that word part. The point isn’t to force a particular strategy into every interaction; it’s to use what students know to help them make meaning.
We approached catalogued differently. Students already knew catalogue as a noun, such as a list of products in a shopping catalogue. I quickly pointed out that the word was being used as a verb in this text, meaning to record or organize information in a document.
Then we encountered blind-devotion. Students understood both words individually but were curious about what the phrase meant in context. I let them discuss their interpretations and build on one another’s ideas. I was ready to step in if they needed clarification, but they didn’t. Their examples demonstrated a strong understanding of the phrase.
The additional vocabulary conversations took no more than four minutes. Some words needed explicit explanation, some called for a quick reminder, and others provided opportunities for students to reason through meaning together.
Wrapping Up: Connecting Words to Learning
After we finished the lesson, students returned to their vocabulary notes. They added a second sentence, using expedition to describe something they had learned from the text and our lesson that day.
Then they shared with a partner whether they had confirmed or revised their initial prediction about how the word connected to the lesson.
This final activity took about two minutes.
Altogether, we spent approximately 15–20 minutes on vocabulary during the lesson. But those weren’t 15–20 minutes taken away from content learning. They were minutes spent deepening students’ understanding of the content, strengthening their knowledge of language, and practicing strategies they can use when they encounter unfamiliar words in the future.
That’s the difference I want vocabulary instruction to make.
Key Takeaways for Educators
- Keep content and students at the center.
Choose words because they help students understand what they’re learning, not simply because they appear on a vocabulary list. Consider what students already know before deciding what they need to be taught.
- Stay flexible and responsive
Prepare for the words students might struggle with, but be willing to adjust. Some words deserve explicit instruction; others need only a quick explanation, and some don’t need instruction at all.
- Keep vocabulary instruction simple and purposeful.
You don’t need an elaborate activity for every word or a rigid plan for every encounter. A well-chosen word and a few thoughtful questions can go a long way.
- Make words part of everyday learning.
Revisit previously taught words, point out connections, and use new vocabulary in your own speech. Encourage students to notice words, ask questions, and experiment with language themselves.
Reflection Questions for Readers
- How could I embed vocabulary instruction more naturally into my content-area teaching?
- What opportunities could I create for students to interact with, revisit, and make connections between the words they encounter in class?
