as Moodle is based on social constructivism, it should go well with CSCL.
As I live in Europe, I payed attention to the site http://www.euro-cscl.org.
They promote FLE3 (python) and Synergeia (java?), no signs of Moodle
FLE3 (Future Learning Environment ; ) is GPL licenzed and quite a nice piece of work (online demo), but there seems to be no assesment .
Synergeia is not totally free.., and I didn't feel geeky enough to install it..
What do moodlers think about CSCL? Is it one of Your/our aims?
our group in Florence has been using Synergeia for a couple of years and we drew inspiration from it for our project aimed to add typical CSCL features to Moodle.
You can here find details and the first chunk of code (as an add-on module named "Forum Plus"):
So, we will be glad to receive any feedback on our work
