Trang 13Four stages of knowing a word
Stage 1: I never saw it before.
Stage 2: I’ve heard of it, but I don’t know what it means.
Stage 3: I recognize it in context – it has
something to do with…
Stage 4: I know it.
(Stage 5: I can distinguish this word from others that are closely related to it.)
Dale (1965: 898)
Trang 14What is vocabulary ability?
The context of vocabulary use
generational usage
language variations
everyday usage/specialized terminology
Vocabulary knowledge and fundamental processes
vocabulary size
knowledge of word characteristics
lexical storage
fundamental vocabulary processes
Metacognitive stategies for vocabulary use
strategic competence (paraphrazing, avoiding, language
switching, appealing to authority, using general terms)
Trang 15Objective testing of vocabulary
“Tests in which the learning material is divided into small units, each of which can be assessed by means of a test item with a single correct answer that can be
specified in advance.”
Reed, J (2000) Assessing vocabulary Cambridge University Press
Words treated as independent linguistic units >
multiple-choice, matching test, discrete item testing etc.
Tests often based on word lists of frequency
Multiple-choice tests discriminate well among levels of ability and are highly reliable
Valid indicators of overall language ability
Trang 16Multiple-choice vocabulary items
Little ongoing research available, except for TOEFL
Difficult to construct; require field-testing, analysis, refinement
Learner may know an alternate meaning of the word, but not the one sought
25% chance of guessing correctly
Items may test knowledge of distractors instead of exact
meaning of target word
Wrong answer may result from lack of understanding of syntax
Permits only limited sampling of total vocabulary knowledge

Little research available on in-depth study
of word-knowledge, except in young
children
BUT: proposals to recognize
Partial vs precise knowledge
Depth of knowledge
Receptive vs productive knowledge

Trang 27Assessing vocabulary size
Native-speaker
Anderson (1996): the average 12 th
grader knows about 80,000
words in L1; children learn up to
4,000-6,000 new words each
year
Miller (1977): children between 6-8
pick up an average of 14 new
words a day
Nagy & Herman (1987): children
acquire 3,000 words per year
Nation (1990): a vocabulary of at least 3,000 word families is necessary to read an academic text with 95% comprehension
Nurweni & Read (1999): first-year university students in Indonesia (w/ 6 years of English) had a vocabulary of about 1,200 words.
Trang 28How to measure vocabulary
size?
Wide variation: students in U.S universities know 15,000 - 200,000 words!
Issues
What counts as a word?
How do we choose which words to test?
How do we find out whether the selected
words are known?
Trang 29The Vocabulary Levels Test
(Nation: 1983; 1990)
Test design
5 levels of word frequency: 2,000, 3,000, 5,000, University word level (5,000+), 10,000.
Word-definition matching (matching
the words to the definition)
Each level has 36 words and 18 definitions
Designed to involve as little reading as possible and to minimize chances of guessing correctly
Intended as a broad measure of word knowledge
Words selected from frequency list on a random basis
Often used as an informal diagnostic tool by teachers; little
research done

Many of the computing patterns used today in elementary
arithmetic, such as those for performing long
multiplications and divisions, were developed as late as the fifteenth century Two reasons are usually advanced
to account for this tardy development, namely, the
mental difficulties and the physical difficulties
encountered in such work.
