Teaching VocabularyEveryday speech uses only 5,000-7,000 words (Klein, 1988)95% of the texts we read consist of about 5,1000 words (Adams 1990).BUT the less common words carry most of the text content and are crucial for understanding that content, particularly in content area courses.•Vocabulary knowledge is closely related to reading comprehension and academic achievement (Chall, Jacobs, & Baldwin, 1990; Graves 2000).•Limited vocabulary is a major factor in the achievement gap (Biemiller, 1999, 2004; Chall, Jacobs, & Baldwin, 1990; Hart & Risley, 1995). 1. What Does ‘Knowing a Word’ Mean? We can summarize ‘Knowing a word’ in the following way:1) Meaninga) Literal meaning b) Meaning in context I’d like to book three seats for tonight’s concert. We booked him for speeding. c) Sense relations 词与词之间的关系词与词之间的关系2) Word Usea) Metaphor and idiom What a word means can be changed, stretched or limited by how it is used and this is something students need to know about. Word meaning is frequently stretched through the use of metaphor and idiom. b) Collocation Word meaning is also governed by collocation – that is which words go with each other.c) Style and register 语体和语域语体和语域 We often use words only in certain social and topical contexts. What we say is governed by the style and register we are in.Style: Style is variation in a person’s speech. Style usually varies from casual to formal according to the type of situation, the person or persons addressed, the location, the topic discussed, etc. Register: A speech variety used by a particular group of people, usually sharing the same occupation (e.g. doctors, lawyers) or the same interests (e.g. stamp collectors, baseball fans). 3) Word FormationWord formation means knowing how words are written and spoken and knowing how they can change their form.a)Parts of speechb) Prefixes and suffixes c) Spelling and pronunciation 4) Word GrammarJust as words change according to their grammatical meaning, so the use of certain words can trigger the use of certain grammatical patterns.a) Nouns: countable and uncountable b) Verb complementation, phrasal verbs, etc. c) Adjectives and adverbs: position, etc. 2 Word Selection for Explicit InstructionDue to the immense amount of words located within school texts, strategic selection of vocabulary to be taught explicitly is required:1) Select a relatively small number of words for explicit instruction, 3-10 words per story or selection.2) Select words that are unknown, critical to the meaning and words that the student will likely encounter in the future.

In teaching active vocabulary, it is usually worth spending time giving examples and asking questions, so that students can really see how the word is used. Passive vocabulary: Words which we want students to understand, but which they will not need to use themselves. To save time, it is often best to present it quite quickly, with a simple example. If it appears as part of a text or dialogue, we can often leave students to guess the word from the context.Receptive vocabulary (Nation)•Being able to recognize the word when it is heard•Being familiar with the written form•Knowing it is made of some parts and being able to relate the parts to its meaning•Knowing the contextualized meaning•Knowing there are some related words•Knowing the words has been used correctly•Knowing its typical connotations•Knowing whether it is uncommonProductive vocabulary (Nation)•Being able to say it with correct pronunciation and stresses•Write with correct spelling•Construct it using the right word parts in their appropriate forms•Produce the word to express the meaning•Produce the word in different context•Produce its synonyms and antonyms•Use the word correctly in an original sentence•Decide to use or not to use to suit the degree of formality of the situation6 Vocabulary learning strategies•Review regularly•Guessing meaning from the context•Use dictionary appropriatelyFor each lexical item in the following random list there is a different way that a teacher could help students begin to learn the meaning:1.
