Outline of Presentation

1. Some basic findings of corpus linguistics

2. Introduction to problems faced by Japanese EFL learners related to vocabulary & reading

3. Introduction to online tools for identifying and teaching vocabulary from authentic videos

Why Focus on Vocabulary?

The seminal work in vocabulary instruction

Nation, I. S. P. (1990). Teaching and learning vocabulary. Boston: Heinle & Heinle Publishers.

The Importance of “Frequency”

Problem 1:

EFL learners don’t know enough high frequency

words…

How many words do L2 learners know? Minimum 5000 words needed for

independent learning(Laufer, 1989, 1992, Nation 2000, etc…)

Japan (University) 2000-2300 800-1200 Shillaw (95), Barrow (99)

Indonesia (University) 1220 900 Nurweni & Read (99)

Germany (age 15, HS) 1200 400 Milton & Meara (98)

Problem 2:

Reading and Listening materials in Japan (i.e.

INPUT) are too difficult…

Vocabulary & Readability: How do MEXT-approved EFL textbooks

measure up?

Junior High:

• Teaches first 1000 GSL 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!

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…

The Forgetting Curve Ebbinhaus (1885), Leitner (1972), Pimsleur (1967), Mondria, (1994)

Repeated viewings foster long-term retention

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.
