I've just uploaded a page on English Raven that features a video and powerpoint display from a presentation I did in Seoul last year at the Pearson Amazing Minds Young Learners and Teenagers conference. The subject was TEE ~ Teaching English in English (or TETE ~ Teaching English through English, as it is often called) and how it related to current English education policy in South Korea.
You can see the video and powerpoint file in one screen at this link:
TEACHING ENGLISH IN/THROUGH ENGLISH
While this presentation was specific to current issues in Korea, if you are interested in the issue/concept of Teacing English in/through English, you will probably find this presentation of some interest irrespective of where in the world you happen to be teaching.
I am considering adding a whole section to English Raven dedicated to specific considerations and methodology for Teaching English in/through English, but for now I'll just see how much interest there is in the issue!
Best,
