Classes and Lectures are taught using an online virtual classroom. Communication is established between the teacher and the students by means of:
* Speaking: teachers and students have the chance to speak one at a time, and everyone participating will listen in through their computer’s speaker. A microphone is needed to participate.
* Writing: participants can send public instant messages that will be viewed by everyone, or a private instant message to a single user that is not viewed by everyone.
* Viewing: Watching slides, videos and notations/demonstrations that the teacher adds during class.
