A Vocabulary Riddle

To comprehend what we read, at least 95% of the words must be recognized

automatically.

How is this possible given the number of words in English?

Oral vocabulary at the end of first grade is a significant predictor of comprehension ten years later.

Cunningham, A.E., & Stanovich, K.E. (1997). Early reading acquisition and its relation to experience and ability 10 years later. Developmental Psychology, 33, 934-945.

Why is a large vocabulary associated with good

comprehension?

The Instrumental Hypothesis

Vocabulary aids comprehension by providing the reader with a tool, or instrument.

The Knowledge Hypothesis

It’s not so much the words themselves that help, but the knowledge they represent.

The Aptitude Hypothesis

Comprehension and vocabulary are correlated “not because one causes the other, but because both reflect a more general underlying verbal aptitude.” – Stahl & Nagy (2005)

The Access Hypothesis

A larger vocabulary means

a deeper understanding of words (including nuances of meaning)

quicker access to words in the lexicon

flexibility in deciding among multiple meanings

The Reciprocal Hypothesis

Being a better reader makes it possible for

you to read more

Reading more gives you a bigger

vocabulary

Having a bigger vocabulary makes you a better reader.

Four Obstacles to Acquiring a Large Vocabulary

1. The number of words in English is very large.

2. Academic English differs from the kind of English used at home.

3. Word knowledge involves far more than learning definitions.

4. Sources of information about words are often hard to use or unhelpful.

– Stahl & Nagy (2005)

How do we learn words from experiences?

gavagai

An aborigine points to a running rabbit and says “Gavagai.” Can you infer the word’s meaning?

Each encounter with a word helps a child narrow its meaning. For example, if he next hears the word gavagai used to refer to a sitting rabbit, the child will infer that running is not connected with the meaning.

Young children learn word meanings from one-on-one interactions with parents and siblings. These interactions may be rich or poor. Consider two examples based on Hart and Risley’s (1995) comparison of families of different socioeconomic levels.

Do I have to eat these?

Yeah.

Do I have to eat these?

Yes, because they have vitamins that will help you grow and get stronger.

“Motherese”

What does it mean to know a word?

A Continuum of Word Knowledge

No knowledge

A vague sense of the meaning

Narrow knowledge with aid of context

Good knowledge but shaky recall

Rich, decontextualized knowledge,connected to other word meanings

Dual Coding Theory

Two systems are involved in learning words. One contains verbal information, the other non-verbal (images). When we learn a word, real-world images that we associate with the concept are also stored. Accessing a word in the lexicon therefore involves both the verbal system and non-verbal (imagery) system.

~ Moral ~When teaching new words, use pictures and other images where possible.

New meanings and even new pronunciations of a word may be added to a child’s lexicon over time.

Is wide reading enough?

Why Wide Reading Why Wide Reading Is Enough Is Not Enough

Vocabulary size andthe amount a child reads are correlated.

Direct instruction cannot possibly account for the number of word meanings children acquire.

Context is generally unreliable as a means of inferring word meanings.

Most words occur too infrequently to provide the number of exposures needed to learn them.

Marzano, R.J. (2004). The developing vision of vocabulary instruction. In J.F. Baumann & E.J. Kame’enui (Eds.), Vocabulary instruction: Research to practice (pp. 100-117). New York: Guilford.

“There is no obvious reason why direct vocabulary instruction and wide reading cannot work in tandem.”

– Marzano (2004, p. 112)

RobertMarzano

The Vocabulary Catch-22

Children need to learn more words to read well, but they need to read well to

learn more words.

McKenna, M.C. (2004). Teaching vocabulary to struggling older readers. Perspectives, 30(1), 13-16.

What are some of the guiding principles of

teaching vocabulary?

Preteach key words to improve comprehension.

Guiding Principle

In 1367, Marain and the settlements ended a seven-year war with the Langurians and Pitoks. As a result of this war, Languria was driven out of East Bacol. Marain would now rule Laman and the other lands that once belonged to Languria. This brought peace to the Bacolean settlements. The settlers no longer had to worry about attacks from Laman. The Bacoleans were happy to be part of Marain in 1367. Yet a dozen years later, these same people would be fighting the Marish for independence, or freedom from United Marain’s rule.

In 1763, Britain and the colonies ended a seven-year war with the French and Indians. As a result of this war, France was driven out of North America. Britain would now rule Canada and the other lands that once belonged to France. This brought peace to the American colonies. The settlers no longer had to worry about attacks from Canada. The Americans were happy to be part of Britain in 1763. Yet a dozen years later, these same people would be fighting the British for independence, or freedom from Great Britain’s rule.

Provide more than definitions.

Guiding Principle

WORD = DEFINITION

Stimulus Response

“She truncated the lights.”

Combine definitions and contextual examples.

Guiding Principle

Minimize rote copying of definitions.

Guiding Principle

Introduce new words in related clusters.

In content areas, clustering words is natural!

But general vocabulary words can be clustered if you work at

it!

Provide brief, periodic review.

Guiding Principle

A Thought Experiment

Group 1

• Receives 1 hour of direct instruction on 20 new words

• Spends 1 full hour of intense review on all 20 words

• This hour is uninterrupted.

Group 2

Group 2

• Receives 1 hour of direct instruction on 20 new words

• Spends 1 full hour of intense review on all 20 words

Group 2

• Receives 1 hour of direct instruction on 20 new words

• Spends 1 full hour of intense review on all 20 words

• This hour is broken into 6 10-minute sessions, 1 per month for 6 months.

Assuming that no one encountered any of the 20 words again, which group would do better on a test after a delay of 10 years?

What did the National Reading Panel conclude

about teaching vocabulary?

NRP Findings on Vocabulary

Teaching vocabulary improves general comprehension ability.

Preteaching vocabulary helps both word learning and comprehension of a selection.

Much vocabulary is acquired through incidental exposure.

Repeated exposures in a variety of contexts are important.

NRP Findings on Vocabulary

A combination of definitions and contextual examples works better than either one alone.

Many instructional methods can be effective in teaching vocabulary.

Instructional methods should result in active engagement.

Both direct and indirect methods should be used.

NRP Findings on Vocabulary

The more connections that are made to a word, the better the word tends to be learned.

Computer applications can be effective. The effectiveness of some instructional

methods depends on the age or ability of the children.

What the NRP said they didn’t know about vocabulary instruction

Which methods work best with students of different ages and abilities?

How can technology best be used to teach vocabulary? How is vocabulary best integrated with comprehension

instruction? What combinations of instructional methods tend to work

best? What are the best ways to assess vocabulary?

To what extent do you see these findings reflected in your core materials?

What are some of the most effective ways of teaching vocabulary?

Some Research-Based Techniques

Read-Alouds Semantic Feature Analysis Graphic Organizers List-Group-Label Semantic Maps (word webs) Word Lines Word Sorts Possible Sentences

Read-Alouds

Planning a Read-Aloud Choose engaging, well-illustrated books. A number of words should be unknown to about

half the students. Choose 3 target words that are important for

comprehension but likely to be unfamiliar. Keep track of the words you choose. Plan to repeat the read-aloud. Plan multiple exposures in the days following.

Conducting a Read-Aloud Be “performance oriented”; read with expression. Include “rich, dialogic discussion.”

Activate prior knowledge. Link the story to experiences of students. Elicit responses from students.

Give direct, clear, and simple instruction in word meanings before the read-aloud.

Give a sentence context from the story in advance.

Discuss words before and after the story. Embed quick definitions while reading. (Biemiller) Do not display pictures while reading (Beck et al.)

Warning!

Spending too much time discussing read-alouds may detract from valuable reading practice.

– Stahl (1998).
