They (1998) made a start by developing deep-word knowledge tests based on word associations for 9 to 11 Dutch children, natives as well as nonnatives.
According to Qian and these researchers, certain…. (The construct of deep word knowledge is further specified as the decontextualized knowledge of word meanings and word associations.)
In terms of mental lexicon, children expand their lexical knowledge at school in the 2 directions. The 1 st one is breadth, which refers to the size…, which mean vocabulary size; the other one is depth, which refers to the amount …. How well these items are mastered? It’s the deep word knowledge or the depth of lexical knowledge. [The number of lexical items known (vocabulary size) vs. how well these items are mastered (vocabulary depth or quality) which means ‘The depth of word knowledge refers to ‘How much do you know of a word?’’ The amount or extensiveness of knowledge of individual words is referred to as deep word knowledge or depth of lexical knowledge .]
2. Therefore, 3. 背 which means that all kinds of connections with related words have to be established. 4. Thus, vocabulary learning might be ‘ more a matter of system learning “ than of item learning ’”(Haastrup & Henriksen, 2000). 補充 In the same vein, learning new words is more than the acquisition of isolated lexical units:
According to John Read (1993), there were 3 types of associations , i.e., the relationships between target word and associates : p relation , s and a. According to Clark (1970), syntagmatic responses are influenced to a considerable extant by the left-to-right production of sentences.
Unlike syntagmatic relations, such as bird-fly, bird-nest, bird-egg, para…. A swallow is the subordination and it’s a migratory bird, and the superordiation is an animal. KK [ˋmaɪgrə ͵ torɪ] (In school, new meanings and new relationships between familiar words are learned by way of a continuing process of generalizing, categorizing and abstracting.) and in this way much academic knowledge is logically organized and can be pictured as a tree structure.
In brief, KK [ ͵ ɪdɪəsɪŋˋkrætɪk] 有特性的 They can figure out word meaning in isolation.
唸 Here are some established assessment instruments. (The key question which will be addressed in the next section is how to measure deep word knowledge. Research on this dimension so far has involved adolescent and adult second language learners (Read, 1993; Greidanus & Nienhuis, 2001; Qian, 1999), whereas in this study we focus on primary school children at a relatively early stage of their second language learning, and their schooling generally.)
As you can see this photo, the teacher says a word, then the child listen and point to the corresponding picture.
The second measure of vocabulary size is the Vocabulary Levels Test The child read and match the correct definition, then write down the number.
Paul Meara This test has 5 levels. If you know what it means, check the box beside the word, ; if you aren't sure, do not check the box.
There are two main methods of measuring depth, described by Read (2000) as developmental and dimensions approaches. Little validation Read (2000) developmental and dimensions approaches. Limitations (see Read, 2000; Schmitt, 2010)
VKS asks learners to rate their knowledge of words not in binary terms (I know/I don't know what this word means) but on a five-point scale (ranging from &quot;I don't remember having seen this word before,&quot; to &quot;I can use this word in a sentence.
The words here on the left side may help to explain the meaning of &quot;sudden&quot;. The words here on the right side are nouns that may come after &quot;sudden&quot; in a phrase or a sentence.
In order to simplify the test for these younger test-takers in two ways: 4. In order to visualize the word associations. (4. …associated with the stimulus word best. What is the best WAF format: 6-option or 8-option?)
Figure 1 is the sample item “banana” from the word association task. Fruit has a paradigmatic relation with banana because it’s the superordination. peel is a part of a banana. It has partonomic association (constituents), and yellow has a distingushing feature and perceptual feature of a banana. Whereas the rest 3 distractors can be associated with banana, but in a more contextualized way!!! In Figure 1, the three related words to be selected are the superordinate fruit, peel and decontextualized syntagmatic relations, the perceptual feature, it’s a distinquishing feature of a banana yellow. Generally speaking, to pick 3 words out of 6 that fit with the stimulus best or always go together with the central word. 1. The intended correct answers represent different kinds of relationship that can be found in a semantic network, such as paradigmatic relations (i.e., superordinate….) 2. Partonomic association 類屬
In order to prevent cheating and to minimize the effects of fatigue or lack of time, …. There were 4 test forms. which might result in the items towards the end not being tested adequately, a variant of each form was created. asterisk [ˋæstə ͵ rɪsk] (WAT-scoring methods were…) Scoring system for the WAT reflects the examinees’ actual knowledge of the words. 2. we considered 改變分數不好的詮釋： Treating each stimulus word – associated word relation (i.e., each (possible) connection) as a separate item causes unwanted interdependence between the items which might inflate reliability estimates. the number of items for which the three intended connecting lines were drawn the word web as just one whole item

分成兩組 The data collection was carried out by test assistant, who had to follow an extensive protocol to make sure the administration of the tests as uniform as possible. They went over the WAT procedure with the children, making use of two sample items (see Section II.1). See p. 218. 2. … to the children, who completed them in class.
The reliability of the test items was estimated in terms of …. To equate the test parts an item response analysis was conducted fitting a two-parameter model using BILOG (Mislevy & Bock, 1986). Scoring students’answers is essentially a mechanical task, and thus rater reliability is not an issue in the WAT. Mislevy, R. J., & Bock, R. D. (1986). PC-Bilog.

Evidence of validity was obtained by…. from a concurrent definition task, and from an analysis of the scores in terms of language background, which is known to be associated with different levels of vocabulary knowledge. The WAT should at least correlate substantially with such a criterion measure. e.g., in this case ....WAT and TAK 互比效度

In sum, this initial analysis indicates that
Table 2 shows that “the test forms for the 3 rd graders had an acceptable degree of difficulty given that the children answered approximately 50% of the 30 items correctly. 藍色五年級 The distributions are skewed [skjud to the left. Small deviations 誤差 from normality are found. 795 children, 405 for WAT-A and 390 for WAT-B WAT-A and WAT-B have 10 items in common and each contains 20 unique items (total 30 items each).

Table 6 shows the correlation between the two scores. Correction for attenuation shows that the correlation can only amount to a maximum of 0.82 in each grade.

Conclusion: the authors claimed that gaining….
All-or-Nothing method vs. a less harsh scoring A well-established test format involving word associations has been adapted for this younger target group and the feasibility of assessing deep word knowledge in primary school children is evaluated empirically. So far we have English tests for the 6 th graders, it is hoped that we could construct our own test format involving word associations to assess deep lexical knowledge. 1-1 Relationships between associates and distractors: semantically related or not? 2-1 Ss can not demonstrate their lexical knowledge.

1. Lexical knowledge in second language acquisition and school
Certain levels and qualities of lexical knowledge are important prerequisites for successful language learning and language use (Qian, 1999; Zareva, Schwanenflugel & Nikolova, 2005), and therefore for school success (Carlo, August, McLaughlin, Snow, Dressler, Lippman, Lively & White, 2004; Saville-Troike, 1984; Snow, Burns & Griffin, 1998).
Mental lexicon the size of the lexicon as the number of ‘entries’ (words) the amount of knowledge of individual words breadth depth
There are multiple components of word knowledge for second language learners to acquire (Nation, 2001).
paradigmatic : the two words are synonyms or similar in meaning, and belong to the same word class, e.g., ‘edit’ and ‘revise.’
syntagmatic : the two words could occur one after another, as collocations, e.g., ‘edit’ and ‘text.’
analytic : the association represents one aspect of the meaning of the target word, and is likely to form part of its dictionary definition, e.g., ‘edit’ and ‘publishing.’
cf. Greidanus, T., & Nienhuis, L. (2001). Testing the quality of word knowledge in a second language by means of word associations: Types of distractors and types of associations . The Modern Language Journal, 85 , 567-577.
The hierarchical classification is characterized by class inclusion .
Dutch as a second language children (DSL) monolingual Dutch peers came up with more syntagmatic, personal, or idiosyncratic meaning associations provided more paradigmatic and decontextualized meanings
From the initial sample of 822 students who were each presented with 30 items, only 15 students sometimes drew more than the required three connecting lines.
Children more frequently marked fewer than three alternatives.
More than 83% of the children marked three alternatives throughout the whole test, and the number of times (i.e., items) that children marked less than three associations was limited to two or three out of the 30 items; only 1% of the children marked less than three alternatives on more than five items.
Gaining more insight into the concept of deep word knowledge is very important as it may reveal vast differences among children who superficially appear to have a similar amount and type of word knowledge.
What are the limitations in measuring how well a learner knows a word?
young EFL learners’ limited vocabulary size > guessing behavior > over- or underestimate vocabulary knowledge
Can the WAT be applied to EFL context in Taiwan?
