I may begin behind the desk, so I can get the students focusing on me, but as the class goes on I, too move around the room (when it i snot an online class). Ideally I would move in and olut of the rows, but because of the way my current classes are set up that is not possible. Even when I have to read off of or refer to a screen I general do it from a different spot in the room.
This movement has a twofold purpose; it assures students I am connect and assures them I am accessible. I think it is important that students understand we are connected that makes a positive impact on them, I believe.
