#99: You Can’t Teach Every Vocabulary Word—So Teach This Instead with Dr. Trina Spencer
You know that feeling when you’ve carefully taught a handful of new words… and then a student opens a book and immediately runs into five more they don’t know? It can make you want to work harder, add more word lists, and squeeze in “just a few more” vocabulary activities.
But here’s the honest truth: there are simply too many words for us to directly teach them all.
So the real goal can’t be “teach every word.” The goal has to be this:
Teach students how to learn words.
The shift: from “teaching words” to “teaching word-learning”
Most vocabulary instruction lives in the “one-and-done” world:
- Here’s a word.
- Here’s a definition.
- Now write a sentence.
- Move on.
That approach isn’t wrong—it’s just incomplete.
What students really need (especially in K–2, and especially for kids who come to school with less language exposure) are transferable language skills they can use later, when you’re not there to pre-teach every term in science, social studies, or a chapter book.
That means building three big abilities:
- Noticing when a word matters (This word is important to understand the sentence.)
- Using clues to guess what it means (context, the situation, examples, contrasts)
- Checking and refining meaning (Does my guess fit? What else could it mean?)
That’s how kids become independent word learners.
What to teach instead of endless vocabulary lists
If you only have time for one “instead,” make it a repeatable routine that builds word-learning muscles.
Here are the highest-impact targets from the episode—because they create the most transfer:
Teach Tier 2 “everywhere words”
These are words kids will meet across subjects and texts (compare, estimate, categorize, explain, result). They’re often the hidden reason comprehension falls apart, even when decoding is solid.
Instead of: teaching 15 random words from one story
Teach: 2–3 Tier 2 words you’ll reuse all week—in read-alouds, directions, math talk, and writing
Teach multiple-meaning words (because they trip kids up constantly)
In early grades, students run into words like play, ground, table, light, bat. If they only know one meaning, entire sentences get misread.
Instead of: assuming kids “already know that word”
Teach: “This word can mean more than one thing. Let’s figure out which meaning fits here.”
Teach sentence-level meaning (not just single-word meaning)
A lot of “vocabulary problems” are actually sentence comprehension problems. Kids may know the words, but not the relationship between them.
So part of word-learning is teaching students to pay attention to:
- who is doing what
- cause/effect language (because, so, therefore)
- compare/contrast language (but, however, instead)
- time/order (first, next, finally)
When students track sentence meaning, they get better at figuring out unfamiliar words inside that sentence.
A simple classroom routine: “Word Detective” (5–7 minutes)
This is the practical swap for vocabulary lists: a quick routine you can use during read-aloud, shared reading, or content lessons.
Step 1: Stop at a “juicy word”
Choose a word that:
- matters for meaning,
- will show up again, or
- has multiple meanings.
Step 2: Put the word back into the sentence
Read the whole sentence again (not just the word). Ask:
- “What’s happening here?”
- “What’s the author trying to tell us?”
Step 3: Hunt for clues
Give kids types of clues to look for:
- Example clues: “like,” “such as,” a list of examples
- Contrast clues: “but,” “however,” “instead”
- Cause/effect clues: “because,” “so,” “therefore”
- Restatement clues: “in other words,” “that means”
Step 4: Try a meaning and test it
Have students say:
“I think ___ means ___ because ___.”
Then test it:
- “Does that meaning make the sentence make sense?”
- “What other meaning could fit?”
Step 5: Lock it in with quick use
Do one fast practice move:
- Turn and talk: “Use the word in a new sentence.”
- Either/or: “Does it mean ___ or ___ here?”
- Quick sketch: “Show me the meaning.”
- Tiny rewrite: “Replace the word with a simpler word.”
This is how you move from memorizing words to learning how words work.
How to make this doable in real life (without adding “one more thing”)
Here are three ways to fit it into your existing day:
Use your read-aloud as your language block
Pick 2–3 words each day and do the Word Detective routine. Over a week, you’ve built deep knowledge of 10–15 high-value words and taught students how to infer meaning.
Reuse the same words all week
The magic is repetition in different contexts:
- morning message
- directions (“Compare your answer…”)
- math talk
- partner shares
- writing conferences
When kids see a word repeatedly, it sticks—and they start using it.
Create a “multiple-meaning word moment”
Any time a word has more than one meaning, make it a 30-second spotlight:
- “What are two meanings of this word?”
- “Which one fits here? How do you know?”
You’ll be shocked how often this clears up confusion that looks like “comprehension issues.”
In This Episode, You’ll Discover
- Why it’s impossible to directly teach all the words students will need
- What “academic language” really includes (beyond vocabulary lists)
- Why Tier 2 words are a hidden driver of comprehension
- How multiple-meaning words quietly derail understanding in K–2
- A simple routine that teaches kids to figure out word meanings in context
- How to build word-learning skills that transfer to every subject
Bringing It All Together
Vocabulary instruction isn’t the enemy. But vocabulary lists alone can’t carry comprehension—not when students will meet thousands of new words across their school years.
The win is teaching students to become the kind of readers who can say:
- “I don’t know this word… but I can figure it out.”
- “Let me look at the sentence again.”
- “Let me test what makes sense.”
That’s the long game. That’s the skill that scales.
