Some elements of etiquette and courtesy will never go out of style, regardless of the social medium. Since online classes are almost entirely conducted with the written word, it becomes very important to write "politely" and interface with your fellow students and colleagues in a positive and constructive manner. Some simple rules may keep you from inadvertently offending others.
Effective online communication requires a level of mutually acceptable and understandable civility. Without the added nuance of facial expression, vocal inflection and body language available in a face-to-face classroom, we are left solely with the sharing of the written word to express our views and with which to understand the specific intentions of our classmates.
Treat others as you would expect to be treated yourself, and that will avoid almost all difficulties.
Recognize that we are all individuals with unique needs, abilities, sensitivities and motivations. Just as in any face-to-face classroom environment, you will find you agree with some, and with others you disagree. Accept that all have something to offer, and that each person brings qualities and knowledge from which the class can learn. You never know, you may even find lifelong friends here at Sandhills Community College!
