Hello Claudia,
Welcome to Classroom 2.0!
I spent a fair amount of time in visiting Guatemala in 1990 and even earlier when I was a young kid.

Hi Claudia,

With your work in Technology integration, I recommend you take a look at Wiziq's virtual classroom and authorstream's power point presentation platform. Both are web based platforms, have a bunch of features and free basic service.
