A graphical interface is easier to use and more visually pleasing to the eye. Plan to log in often. Daily is ideal, but at least every other day will allow you to track the developing discussion groups, add your contributions and check for new information. This on line time can be brief and you will stay on top of the class information. Getting behind can overwhelm some individuals.
Flexibility is an important component for on-line learners.
Dates for activities may change, technical problems can occur, and some topics will generate more interest and discussion than others. Keep your comments focused on issues and not individuals. Attacking a person for having a stated belief or idea is not acceptable. This would not be tolerated in an on campus class and is not acceptable on-line. Use appropriate language in your dialogs with others.
