Moodle
For my Google Summer of Code project I am working with the open source project Moodle (Modular Object-Oriented Dynamic Learning Environment) which is a PHP based teaching CMS (course management system) which can be used to create web based courses and manage real life ones as well. Moodle offers a much cleaner and simpler system then black board and WebCT (both of witch i have been forced to use as a student for online classes and classes at Lakehead) and is apparently scalable for use by a signal teacher to use by a whole university.
My work consists of creating a new plug-in for the gradebook module in Moodle witch will display statistics relating to grades as well as using Flare (which is a visualization toolkit that uses ActionScript and Adobe Flash) to create some cool looking visualizations of the grades, outcomes and statistics relating to them. The plan is to develop this plug-in for Moodle 2.0 (the future release of Moodle) and then back port it to Moodle 1.9.X (the current release) or make it compatible with both. The original proposal can be found here and the specification for the current project is posted on the Moodle wiki here. If you know anything about Moodle or teaching (or even if you don’t) feel free to comment on the spec here or on the page comments on the wiki.
