teaching and learning Desire for a technology that closely replicates
the face-to-face classroom model

Know Thy Learner Analysis, analysis, analysis Are they MOTIVATED? If so, what are
their motivations? Can you describe the targeted learner? Have they participated in a videoconference?
If so, what were their experiences? Is videoconferencing the most effective way
to reach your learners?

Three Key Questions!
What do I want the learners to be able to do?
How will I know if they can do it? How can I tell when they are doing it
right?– provide criteria for assessment– request feedback throughout class

Prepare for Worst Case Scenario Provide contact information for technical support. Have a phone at each location. Designate a remote facilitator. Develop a contingency plan for the remote site(s)
and share it with the remote facilitator. You might, for example, have a discussion topic or
activity that supports the videoconference outcomes.

Prepare for Worst Case Scenario Share telephone numbers with your remote
facilitator and troubleshooters. Establish your connection 15-30 minutes prior
to the meeting time. Most technical problems are observable when establishing a connection.
If you have never connected with your remote site plan a "dry run" a week or so ahead of time.
