Going out to play after school or visiting a school friend on the weekend may be impossible. When a discussion forum is available, they have an outlet for their need to connect with others. They can chat with their friends about the day, school assignments, and interests. There is no barrier other than access to the online world. A stutter, wheelchair, tremor, or inability to see is transparent in this world.
Access is equal.
Ideas are emphasized. Only classmates are part of the discussion forum community. The teacher controls access and can monitor discussion cutting off access to those abusing the space. Again, student's abilities to communicate, think, write, analyze, and socialize are all reinforced in an atmosphere that is low stress and high interest - perfect for students with disabilities as well as their classmate. Technology can be a great equalizer for the disabled population when given access and training in its use.
