Is “cutting edge” really the way forward in CALL? • 1990: Director of Sony Language Laboratories • 1995: helped design CALL center at Aoyama Gakuin • 2004: published “New Perspectives in CALL” • 2006: introduced 1st online vocabulary test and flashcards at JALT-CALL in Sapporo • 20o9: Began developing online learning tools for teaching via authentic video • 2011: JALT-CALL Plenary – YAY!
A recipe for success in CALL… • Figure out what kinds of things technology does better or faster than humans can • Figure out what are the weaknesses and problems teachers and learners face in the EFL classroom • Figure out what the comfort zone/ability level of the average teacher and student is • Using an informed approach to CLT, try to develop software and technologies that assist teachers and learners
Outline of Presentation • Some basic findings of corpus linguistics • Introduction to problems faced by Japanese EFL learners related to vocabulary • Introduction to EnglishCentral as well as a range of free online tools for identifying and teaching vocabulary from authentic videos
Some Opening Questions: • How many words do you think there are in the English Language? • 1,000,000 (Stanford research group, 2008) • 350,000 (Oxford English Dictionary) • How many words does a typical native speaker know? • 20,0000 (Goulden, Nation, Read, 2000)

Problem 1:EFL learners don’t know enough high frequency words…
EFL Vocabulary Learning in Japan… exasperate digress abstain emigrate torment chaos chaos permission permission and of the and of the Frequency 350,000 ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ • 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… 84,168 42,024 25,537 23,371 14,641 5,000 4,441 ace 2,566 bid HFW 2,289 sum 3 2 1
Problem 2:Reading and Listening materials in Japan (i.e. INPUT) are too difficult…
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% ?
75% Coverage 1000 high frequency words [ 19 missing 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)
85% Coverage 2000 high frequency words [ 13 missing 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 _____ _____.

95% Coverage 5000 high frequency words [ 4 missing 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)
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)
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!
