ATutor

What sets ATutor apart from the others is its support of accessibility and interoperability standards. There's nothing to stop a course designer from exporting a course, and moving it to another server, or even another system. There is no "lock in" as is the case with most other system. And, any user can access the system as a student, instructor, or administrator without the barriers that are present in virtually all other systems. A blind person could manage an ATutor system, or design a course, or takes one.

Adaptability is another key focus of ATutor. A course is a collection of tools, which could simply be a single forum for example, to support a classroom course, up to a full collection of tools to support a independent online course. Learners can also adapt the system to their needs, controlling the look and feel of the system, controlling the navigation elements, and adapting content to work best for their abilities and learning styles.
