PROBLEM DEFINITION

• Moodle forums lack many features found in social networks that would be useful for helping students learn better

• Moodle does not encourage social interaction between users, which keeps it from effectively building a community of learning.

• Much information about students cannot be discerned from purely classroom interactions. While Moodle is not intended for that, it would be valuable information for educators.

Authorization: Any user can be a student or a teacher, depending on the course context. The context is used by vMoodle to determine the status of a user. Teachers have access to all the student score information.

Privacy: The application requests the users permission to use their information before admitting the user. That information is only exposed to the teacher. Passwords are encrypted.
