I've just finished listening to this wonderful interview of Professor David Gray of Shinshu University. I'm an ESL teacher myself. I'm in my 46th year of ESL teaching. 15 of them were in Japan. I think Professor Gray describes the method very clearly and effectively. And I agree that there's great potential there. I hope a lot of teachers will listen to this excellent interview and that it will have a positive impact on their teaching. Good job, everybody.
