This summer I plan to upgrade to Moodle 2.0. I know not every plugin we use will be compatible, so I have just begun making a list of what we absolutely need and finding if there is a 2.0 version available. There are some pretty exciting developments with Moodle and I am itching to get started!
The one new development for Moodle 2.1 is the new Mobile App! https://docs.moodle.org/en/Development:Mobile_app I think this new mobile app will really make for interesting use of Moodle. Imagine students on a field trip using the App to add information into the course as they explore a museum or collect data from an experiment for science.
Moodle 2.0 will also sport new question bank features and improvements.
Another neat plugin I found was the FlexPage Course Format. It allows teachers to setup Moodle courses in a more traditional way by adding pages for each section of their course which is easier to follow compared to topic format.
Looking forward to upgrading in the next couple of weeks here!
