Knowing your students and their personality traits
We all communicate online daily. We send emails, text messages, and often communicate through instant messaging. Words and attitudes can be misconstrued by the recipient as it is often hard to determine the tone of many electronic messages. Some are short and to the point and come off as being abrupt. It is important for learners and instructors to be very aware of how their electronic communication is going to be received. Always read your own emails before sending them. You may find that they sound abrupt or unlike what you are trying to say. I read every email before sending it so that I know I am expressing what I am trying to say without it sounding harsh and it gives me an opportunity to proof for typos and errors.
I, too, read everything that I send out. I try to make them sound like I am talking to them face to face. I also try to put a little humor in my correspondence.
