It's a very well-done video that shows the on-the-ground reality - in the classroom - of language immersion.
I'm still neutral on language immersion. On review, however, it does offer impressive new vistas, and opportunities that would open up to our kids.
Certainly, as the world shrinks, we can do more to put foreign language instruction back into our schools.
I don't have the answer to how this can be done, or whether immersion is the only way, but watching that video creates a desire to see more minds opened up to the possibilities of other languages, and all the advantage that implies.
If we could simply move beyond the political rancor that's associated with immersion, and *make better instruction happen* (by enabling our teachers, and funding programs), our kids will win (and so will our future world).
