5 Some Opening Questions: 1.How many words do you think there are in the English Language? 1,000,000 (Stanford research group, 2008) 350,000 (Oxford English Dictionary) 2.How many words does a typical native speaker know? 20,0000(Goulden, Nation, Read, 2000)

7 Coverage within the BNC for high frequency words (Leech, Rayson, & Wilson, 2001)

8 Coverage within the CIC for high frequency words (McCarthy, 2002)

9 Problem 1: EFL learners don’t know enough high frequency words…

10 10 1 2 3 ・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・ Frequency 350,000 5,000 EFL Vocabulary Learning in Japan… chaos permission and of the exasperate digress chaos permission and of the abstain emigrate torment The Negative Effect of “Test English” PROBLEM: Students NEED to learn the first 5000 words of English to use English in the real word… But entrance exams and high school textbooks force students to memorize hundreds of low-frequency words… RESULT? High school students can’t deal with real world English because they don’t know hundreds of the most important high frequency words… sum bid ace HFW 2,289 2,566 4,441 14,641 23,371 25,537 42,024 84,168

11 Problem 2: Reading and Listening materials in Japan (i.e. INPUT) are too difficult…

12 When reading or listening to a text, students will of course will not know many words… What percentage of words do you think must be known for them to be able to read easily? 50% ? 75% ? 85% ? 95% ?

13 75% Coverage 1000 high frequency words …another possible problem with _____ _____ is how to _____ learner _____ although research suggests that _____ are a very _____ way to learn new words (Leitner, 1972, Mondria, 1994, Nation, 1990, 2001), students may lose interest if _____ are the _____ _____ of doing _____ _____. There is a _____ _____ in the _____ classroom of using games with a _____ purpose to increase and _____ learner _____ (Ersoz, 2000, Uberman 1988, Wright, Betteridge & Buckby, 1984), as well as lower the learner _____ _____ (Asher, 1965, 1977, Dulay, Krashen & Burt, 1982) [ 19 missing words ]

14 85% Coverage 2000 high frequency words …another possible problem with _____ _____ is how to _____ learner _____ although research suggests that _____ are a very efficient way to learn new words (Leitner, 1972, Mondria, 1994, Nation, 1990, 2001), students may lose interest if _____ are the _____ method of doing _____ _____. There is a rich tradition in the _____ classroom of using games with a communicative purpose to increase and maintain learner _____ (Ersoz, 2000, Uberman 1988, Wright, Betteridge & Buckby, 1984), as well as lower the learner _____ _____ (Asher, 1965, 1977, Dulay, Krashen & Burt, 1982) [ 13 missing words ]

15 95% Coverage 5000 high frequency words …another possible problem with vocabulary _____ is how to sustain learner motivation although research suggests that _____ are a very efficient way to learn new words (Leitner, 1972, Mondria, 1994, Nation, 1990, 2001), students may lose interest if _____ are the sole method of doing vocabulary review. There is a rich tradition in the _____ classroom of using games with a communicative purpose to increase and maintain learner motivation (Ersoz, 2000, Uberman 1988, Wright, Betteridge & Buckby, 1984), as well as lower the learner affective filter (Asher, 1965, 1977, Dulay, Krashen & Burt, 1982) [ 4 missing words ]

16 Vocabulary Thresholds: Below 80%, reading comprehension is almost impossible (Hu & Nation, 2001) 95% coverage is the point at which learners can read without the help of dictionaries (Laufer, 1989)

17 Vocabulary & Readability: How do Japanese schools measure up? Junior High: Teaches first 1000 words fairly well Readability of texts seems good - short passages, easy vocabulary, lots of pictures to support texts Senior High: Focus changes dramatically to teaching of low frequency words Many, many words from 1000-2000 are never taught… Readability of texts is actually MORE difficult than unsimplified native speaker texts!

49 100% 0% Bilingual Captioning Select difficulty level of videos you want Click on video you want to study

50 100% 0% Bilingual Captioning Transcripts available for pre- listening study Key vocabulary words selected for study by corpus analysis

51 100% 0% Bilingual Captioning Captioning in English, Japanese, or both Transcripts can be hidden by pushing these buttons

54 Solution Number Four: KEYWORD LEARNING In-context, spaced-repetition vocabulary learning system

55 100% Short-term memory loss 50% 0% Time

56 100% 0% The Forgetting Curve Ebbinhaus (1885), Leitner (1972), Pimsleur (1967), Mondria, (1994) Repeated viewings foster long-term retention

57 Spaced Repetition is the science of long-term memory Based on the research of Ebbinghaus, Pimsleur, Leitner, and Mondria, electronic flashcards automatically repeat each new word at spaced time intervals, and until the learner achieves long-term, instant-recall ability.

68 Vocabulary Flashcards: by corpus analysis of videos (1) Select a video category to study

69 Vocabulary Flashcards: by corpus analysis of videos (2) Go to the vocabulary application, then click on the list of words from the category you want to study

70 Vocabulary Flashcards: by corpus analysis of videos (3) Study the words as a list, or just pick a word to learn it in all the different contexts it occurs in the database

71 Vocabulary Flashcards: by corpus analysis of videos (4) All clips in the database which contain your keyword are played in context, in succession. You can listen only or record your voice and compare to the native speaker

72 Vocabulary Flashcards: by corpus analysis of videos (5) Study your words in QUIZ mode to work on definitions in context, listening and CLOZE type activities

73 Vocabulary Flashcards: by corpus analysis of videos Quiz mode is based on Ebbbinghaus, Leitner and Pimsleur’s “spaced- repetition” approach

74 Vocabulary Flashcards: by corpus analysis of videos First, the meaning and context of 2-3 new words are introduced via video flashcards
