A lot of people come to this site searching for “open source LMS”. These are some of the web-based learning systems that I have used, and would recommend:
- Elgg – for informal web-enabled learning where the learner is the centre of it all. Though still in its early development, I would recommend Elgg as a virtual space to foster community outside of the course-based LMS.
- Moodle -a constructivist web environment for more formal learning with an extensive user base worldwide. Combining Elgg and Moodle makes an excellent choice for formal and informal learning.
- ATutor – a Canadian-based web learning system designed for accessibility and with a number of easy to add modules, such as collaboration.
There are many others, many of which are reviewed on EduTools, and I’d suggest that you go to my Open Source for Learning lens for further links.
