I have found that adding an "Introduction Discussion Thread" in the first week of class allows students the opportunity to form a "community" within the class that makes them feel at ease. The first post of a BIO by the instructor will allow the students a way to interact with the instructor on a personal basis. The instructor's BIO will also set the tone for students to post their information and respond to others. Forming a sense of community in the class is an important part of an online class experience and can help each student feel that they belong. On a personal note, what would you want to share with your students in your BIO?
