This assignment will be tailored for each remote group's access to technology.

  1. Post a graphical organizer for the topology and connectivity involved in the connection. (Inspiration or another tool would be a good software package to use).

    Discuss in the posting your thoughts of the process and how you would instruct the process to someone else.

    How is wireless communications effecting your teaching now and how do you think it will effect it in the future ?

  2. Briefly explain why a direct tv high-speed data link might not be the best Internet Service Provider (ISP) to hook up with if your primary use is participating in on-line real-time collaborative communications?
