I have no problem with spanish being taught as a SECOND language. Or French, or Russian or Chinese — as long as English is our FIRST language.
I was thinking the same thing. If it works with Spanish/English (and granted, that is the easier and more obvious case) then they should push the experiment a little further with French or German or Chinese. Finding Spanish speakers to staff the program is probably easier than some other languages, especially away from larger cities, but I would love to see it tried where possible.
I remember that when I was in high school, four languages were offered. Spanish, French, German, and Russian. The language programs have atrophied along with everything else over the years it seems. We used to have a huge and varied vocational ed program, and a large and very active music program. I don't see so much of that these days. We spend more than ever but they say the money isn't there.
