3 Warming Up Number of words in the English language: Number of words a university- educated native English speaker knows: Number of words that you know: Vocabulary size needed for basic communication (i.e., to express what one wants to express, however simply): Vocabulary size needed for reading (understanding any written text): Can you think of a good way to measure people’s vocab sizes?

4 Number of words in the English language: 1 to 2 million words (Schmitt, 2000) Goulden, Nation & Read (1990) estimated that Webster’s Third International Dictionary (published in 1961) contained around 267,000 entries and 54,000 word families. Number of words a university- educated native English speaker knows: 20,000 word families Vocabulary size needed for basic communication (i.e., to express what one wants to express, however simply): 2,000 most frequent words West’s (1953) General Service List (GSL): 95% coverage of informal spoken English (but only 80% coverage of written English) Vocabulary size needed for reading (understanding any written text): Students need to know 95%-98% of the words in a text in order to understand the text (5,000 words – about 90% coverage) (15,000 words – about 98% coverage)

7 How many words do you know? (Measuring vocab size) take a dictionary and count the number of words that you know on 10 pages chosen at random. Divide the total by 10 and multiply by the number of pages in the dictionary. Paul Nation’s Vocabulary Levels Test Paul Nation’s Vocabulary Levels Test http://www.lextutor.ca/tests/which contains Nation's Vocabulary Levels Tests (VLT) that test vocabulary knowledge at different frequency levels (from 1 – 14 K), words taken from the British National Corpus (BNC). To measure your vocab size, attempt all the 14 tests; add up the scores you get at these 14 levels and then multiply the total score by 100. http://www.lextutor.ca/tests/

9 What do you think are the ten most frequently used words in English? 10 most frequently used words 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.

10 West (1953)’s General Service List (GSL) (2000 headwords) (Appendix 2) Based on a 5 million word written corpus Based on a 5 million word written corpus % given for different meanings and parts of speech (see Appendix 5) % given for different meanings and parts of speech (see Appendix 5) How to make reading texts more comprehensible for learners How to make reading texts more comprehensible for learners Replacing difficult vocabulary with the GSL words, selected according to: Replacing difficult vocabulary with the GSL words, selected according to: Frequency Frequency Universality (words used in different countries) Universality (words used in different countries) Range (words used to talk about a range of topics) Range (words used to talk about a range of topics) Usefulness (words used to define other words) Usefulness (words used to define other words) Despite its age, validated by later studies to be providing an average of 82% text coverage (Hirsh & Nation, 1992; Sutarsyah, nation & Kennedy, 1994) Despite its age, validated by later studies to be providing an average of 82% text coverage (Hirsh & Nation, 1992; Sutarsyah, nation & Kennedy, 1994) Nation (2004) compares the GSL, AWL, and the most frequent 3,000 words in the BNC, and found that 88% of the words on the GSL + AWL are found in the BNC’s most frequent 3,000 words, and concludes that the GSL, though compiled much long before the BNC, is still valid when complemented with the AWL. However, he suggests that some words like computer, drugs, television can be added into the GSL. 9

11 Xue & Nation’s (1984) University Word List (UWL) The University Word List (UWL) first compiled by Xue and Nation (1984) has 836 words that are frequently used in academic texts but are not included in the GSL. Later revised by removing words already existing in the AWL (see Appendix 4 for the Revised UWL) 10

12 Coxhead’s (2000) Academic Word List (AWL) (570 headwords) Used a corpus of academic texts from Science, Humanities, Commerce, and Law identified words that are frequent in all of these 4 subcorpora (having a wide “range”) excluded words that already exist in GSL See Appendix 3 11

13 Frequency Lists Nation and Waring (1997) (pre-session 2 reading) suggests that a list of high frequency words used in a course should provide: Nation and Waring (1997) (pre-session 2 reading) suggests that a list of high frequency words used in a course should provide: Core meaning of the word Core meaning of the word Different word forms and parts of speech (word family) Different word forms and parts of speech (word family) Variations of meaning (for polysemous words – words that have more than one meaning) Variations of meaning (for polysemous words – words that have more than one meaning) Frequency information of the different meanings & uses Frequency information of the different meanings & uses Collocations Collocations Restrictions on use of the word Restrictions on use of the word 12

14 Recommended sequence for learners First 2,000 words (the GSL) 80% of text coverage First 2,000 words + AWL 90% of text coverage of a text that a student would typically read First 2,000 words + AWL + Technical vocab 95% of text coverage of a text that a student would typically read First 2,000 words + AWL + Technical vocab + most frequently used prefixes, roots and suffixes 13

15 Strategies for learning words of different frequency levels 5,000 Word Level (general vocabulary) Training at guessing words in context Wide general reading : novels, newspapers and magazines Intensive reading of a variety of texts Advanced English Vocabulary workbooks University Word Level (specialised academic vocabulary) Learn the words on the University Word List (Nation 1990) and Academic Word List (Coxhead, 2000) Intensive reading of university texts 10,000 Word Level (a wide, general vocabulary) Activities similar to the 5,000 word level, combined with learning prefixes and roots

It also checks the range of a word in any of the 15 sub-corpora of the Brown Corpus, i.e. in which and how many of the 15 sub-corpora a word can be found. The sub-corpora cover a wide range of domains such as press, academic, and fiction. Corpus-based Range checks whether a word is used more frequently in spoken or written English in the Brown Corpus.

I have a rubber, an old, small rubber. Although it is so small that I can not use it anymore, I still keep it carefully in my drawer as it is so important for me. That is a long, long time that I have my rubber. Four years ago, when I was still an eight-years-old child, my parents bought me a rubber as my birthday present. I put it into my pencil-box and brought it to school everyday. That is a long, long time that I have my rubber.

26 Text written by a local HK 16-year old under exam conditions Many students strive for academic excellency, but what is the motivation behind their hardwork? In this essay, I am going to explore the different aspects of learning, and analyse the pros and cons of each motivating factor. Many students strive for academic excellency, but what is the motivation behind their hardwork? In this essay, I am going to explore the different aspects of learning, and analyse the pros and cons of each motivating factor. The hunger for knowledge and wisdom can motivate students to learn. They hope to widen their horizons through reading, watching educational programs, travelling and other ways. To them, the world is a fascinating place, full of wonders and mysteries to unravel. Their love of learning motivates them to seek knowledge in all areas, from science and mathematics to arts. The hunger for knowledge and wisdom can motivate students to learn.

My heart sank. Then my teacher took away the paper and put another one in front of me. I took it and saw an 88 in the mark box. The first paper belonged to my neighbor, Sally.

32 What are the benefits of using word lists (such as GSL, AWL)? To design a vocabulary curriculum To design a vocabulary curriculum To decide which texts to use with students To decide which texts to use with students To identify words in a text that would cause difficulty to students and then replace these words with higher-frequency words to make the text more comprehensible to students To identify words in a text that would cause difficulty to students and then replace these words with higher-frequency words to make the text more comprehensible to students 31
