I think it'd be cool to teach somewhere where students are really engaged in the learning process. In this respect, are some of these locations/cultures better choices than others?  If it's not location/culture-specific, then are there certain teaching placements -- e.g., colleges vs. public schools, etc. -- that might offer this kind of experience more than others?  

 

For what it's worth, I'm a native English speaker with a Bachelor's degree (in Psychology), but I'm not ESL certified.
