Shalom, Salut, Salve!
I have just been to one of the SL-lessons at Babel School. A German class with an American and a CostaRican.
Finally, I have seen what it looks like – in the end I am also one of the teachers! :) And I have to say: we need more structure. More stucture and more utilities, like tables, pictures, etc. Much time is needed to type things.
But on the other hand, in general, this is indeed a wonderful possibility of interaction, which is not yet seen by many SL residents. “Learning through playing” if you want. We can be flexible, in both meanings: change the subject or a study plan, and also the place, or ourselves. But there can be so much more!
I wonder what it will be like, as soon as we have audio here. That will be really crazy.
