Why?

What we’ve known for a long timeWhat we’ve known for a long time
Vocabulary knowledge is a powerful predictor of reading comprehension.
By 4th grade, many children experience a slump in reading comprehension caused by below-grade vocabulary.
IRA, 2008
And more recently . . .And more recently . . .
Evidence of how strongly early vocabulary relates to later literacy
Growing awareness of individual differences--and how they stick around
IRA, 2008
Specifically -- Specifically -- Studies have shown Studies have shown
• Vocabulary size in kindergarten predicts reading comprehension in the middle elementary years.
• Orally-tested vocabulary at the end of 1st grade predicts reading comprehension 10 years later.
IRA, 2008
Little attention is given to vocabulary knowledge in schools. (Biemiller, 1999; Blachowicz, Fisher, Ogle, & Watts-Taffe, 2006)
WHAT?
Classrooms are full of words! Students are faced with oodles of words.
However . . . However . . .

Teachers spend “little time discussing the meanings of words” (Scott, Jamieson-Noel and Asselin (2003, p. 282).
Words introduced with a reading selection rarely followed up (Walsh, 2003).

Cautions on Learning from Context Cautions on Learning from Context
• oral vs. written• wide reading • individual differences • not all contexts are created equal
IRA, 2008
Use of Context Use of Context
High ability readers are better able to use context clues to gain meaning:
54% vs. 40%
Even high ability readers in a situation with strong context support don’t always get the meaning:
82% vs. 69%

Contexts are not Created EqualContexts are not Created EqualElla watched as Nora got smaller and smaller and finally ________.

3. Learning is incremental3. Learning is incremental
A word is not learned the first time it is encountered.
A learner needs:
• various facets of information about a word
• practice in use of a word
• to integrate a word into existing knowledge

What is the result of "mentioning" and "assigning" instruction?
Students may learn words as measured by multiple choice tests.
No effect on comprehension (Bauman, Kame’enui & Ash, 2003; Stahl & Fairbanks, 1986).
IRA, 2008
Why Lack of Effect?Why Lack of Effect?
Comprehension requires rapid and rich access to word meanings.
Instruction needs to go beyond associating words with definitions.
IRA, 2008
Instruction, Yes, But Which Words?Instruction, Yes, But Which Words?
Surprisingly little attention
Selection in most studies: “words judged unfamiliar.”
Careful selection is important because we can’t teach all words.
Word Tiers

Choosing Words to Teach: Choosing Words to Teach: Three Tiers Three Tiers
Starting point: words in the language have different levels of utility.
Tier One: • the most basic words • clock, baby, happy • rarely require instruction in school

Tier Three:• words whose frequency of use is
quite low, often limited to specific domains • isotope, lathe, peninsula • probably best learned when
needed in a content area

Why Teach Tier 2 Words?Why Teach Tier 2 Words?Consider the gulf between:
Everyday language• highly frequent corpus• Redundancy with context
and
Language for literacy• rarer vocabulary• building ideas from words alone
Lexical bar: Students must cross it for academic success (Corson)

Crossing the Lexical BarCrossing the Lexical Bar
Students need to master the kinds of words that provide entrée into the world of texts.
These are the words literate language users need for comprehending texts that express new ideas: Tier 2 words

The inhabitants of Framboisy are worried. The bridge across the River Clarinette is near collapse, and without it they will lose touch with the rest of France. The innkeeper, grocer, and teacher gather as the mayor approaches to report that there are no funds to rebuild the bridge.
The Bridge on the River Clarinette by Pierre Gamarra
“We’re ruined. No one dares to venture across our dilapidated old bridge.”
A stranger appears, coming across the bridge.
“What an odd person . . . Look at his uncanny smile, and the glint in his eyes,” the teacher says.
IRA, 2008
To the astonishment of his audience, the stranger explained, “Give me your words, and I will build you a magnificent bridge in five seconds. I will leave you a few words for your daily needs—drink, eat, sleep, bread, butter, coffee…”
“So you’re a magician?” asked the innkeeper.
“I have a very advanced technique at my disposal,” the stranger replied modestly.
“We could at least give it a try,” said the grocer.
“You agree?” said the stranger with a malicious swiftness.
IRA, 2008
“Agreed,” said the mayor, the innkeeper, and the grocer.
“I object!” cried the teacher. “We should never give up our words. And it’s crazy. Who could build a bridge in five seconds?”
The stranger pointed -- and there arose a beautiful three-arched bridge.
The mayor nudged the innkeeper, “Bread, butter, eat, drink.”
The innkeeper replied, “Drink, sleep, house, chair.”

Rationale for the words selectedRationale for the words selected
• Inhabitants defines the characters of the story, and the word has a rich morphological family—habitat, habit, inhabit.
• Dilapidated is the state of the bridge that provides the central problem of the story—and it is a great word to say, and makes for good images.

Rationale for the words selected, cont.Rationale for the words selected, cont.
• Malicious is key to the motives of the stranger, and is a delicious word.
• Uncanny is the essence of the character of the stranger, and it has a strong, unique meaning.

“He was devious on his bike.”
students frequently interpreted one or two words as the entire meaning (Scott & Nagy, 1989)

What Kind of Instruction?What Kind of Instruction?
Considering the goal is to affect student’s ability to comprehend text
• Both definitional and contextual information
• Multiple exposures in different contexts• Depth of processing • Frequent encounters
(Stahl & Fairbanks, 1986)

Say inhabitant if I describe a place that you would want to inhabit--if you would want to live there. Why?
• The North Pole
• A tropical island

Describe the most malicious character you’ve ever read about or seen. Use astonished and uncanny in the description.
“On its last legs” = dilapidated
How else can we say that?
Think of 3 things you could describe that way.
