Back in 2006, we brought word that middle and high school students in Kyoto Prefecture's Yawata City were using the DS to study vocab. Now, in 2009, the front page of today's Yomiuri Shimbun says...
Elementary school students in Kyoto Prefecture's Yawata City are using the Nintendo DS to study English starting this April. The DS software will contain 600 words and 150 phrases.
Can't wait until 2012 when it's announced that pre-schools in Yawata City are using the DS to learn English or 2016 when the city launches fetus DS English language study. Maybe that'll be in 2020. Hey, like we know.
