When teaching an Online Class, it is important to first know if this is a class where students would all be seen on web cams, or where students are merely chatting in a chat room.

If students and the teacher are all visible on web cams, then it is important for the teacher to use visuals to reinforce the concepts and vocabulary being taught.

If the teaching is done only via chat, then the teacher needs to have the students practice what the teacher models.
