By the way, can I amend my earlier answer about teaching ESL or ESOL or whatever they call it these days since new acronyms always mean progress...

I have a feeling you're tuned in to how your students are doing, and what I wanted to add was...I think before, I said: go ahead and immerse them in English because it's only an hour a day. But the addendum is if they seem stressed out anyway, I think it's worth slipping them some Spanish. My big lesson from Middlebury is you learn languages better if you're not stressed out.
