    Slide 2:Remember George Jetson?

    Remember the Jetsons? Remember all the great futuristic gadgets and devices they had to simplify life? Remember George Jetson receiving a videoconference call from his boss, Mr. Spacely, right as he had dozed off for a nap? Well, ready or not, those Jetson-style days are here and have been here for a while even in the classroom. A quick look at the early videoconference tools – videophone and picturephone it was called.

    Slide 3:Early Video Conference – Picturephones

    For decades, we've seen videoconferencing depicted as the technology of the future. But while videoconferencing has been around for years, it hadn't offered the quality or convenience George Jetson or Captain Kirk would expect. BUT now those two might be happy. BTW - The first Picturephone test system, built in 1956, was crude - it transmitted an image only once every two seconds. But by 1964 a complete experimental system, the "Mod 1," had been developed. To test it, the public was invited to place calls between special exhibits at Disneyland and the New York World's Fair. In both locations, visitors were carefully interviewed afterward by a market research agency.   People, it turned out, didn't like Picturephone. The equipment was too bulky, the controls too unfriendly, and the picture too small. But the Bell System was convinced that Picturephone was viable. Trials went on for six more years. In 1970, commercial Picturephone service debuted in downtown Pittsburgh and AT&T executives confidently predicted that a million Picturephone sets would be in use by 1980. I (Sandy) was musing on that the other day while reading an article in Communications Daily which said "Four decades after the 1964 World's Fair in New York unveiled the first picture phone, cable operators, equipment manufacturers, other tech vendors and independent phone providers are gearing up to introduce broadband videophone service to consumers."

    Slide 10:Network Choices

    Advantage: Free within the LAN, WAN line sharing Disadvantage: LAN contention, bandwidth hog TCP/IP (LAN) Dial-up Network

    Advantage: High Bandwidth, fixed cost Disadvantage: Only “Point A” to “Point B”

    Slide 13:IP Video Conferencing

    Dial-up IP to IP Dedicated equipment Professional services Server Based AIM, iChat, Netmeeting, iVisit, SightSpeed etc. We at home use iChat a lot. It's the number one, best home videoconferencing unit. I've used it in meetings, too, but for class/large group use, she/he will need the Polycom/Tandberg solution. iChat works well one-on-one and would be fine for a class to homebound but that's about it.

    Slide 24:6 Tips

    Colors: clothes, color coding, color discussions Breaks, breakouts, and briefs Lunches and labs Engaging quieter students Guest presenters Pre-course tools, communications, and assignments.

    Slide 25:Tip #1: Colors

    Clothes Wear bright colors and invite students to wear VC-friendly colors (Blues, Violets, Pinks…even orange!) Point out which colors and patterns to avoid, such as shirts that are all-white or wild, checkered sweaters. Color Coding Consider colored name tents to see student names and category (type project, subject) Color discussions Back drops, wall colors, signage.

    Slide 26:Tip #2: Breaks, Breakouts, and Briefs

    Breaks Exercise breaks Rotate seats, so different groups get to “center stage” from time to time. Breakouts Small group assignments (10-15 minutes) Briefs Mini-presentations by small groups Student introductions Student project “snap shots” (1 minute max)

    Slide 27:Tip #3: Lunches and Labs

    Lunches If class is on either side of a lunch break, consider running mini-film festivals on supporting information. (History or Literature classes w/ snippets of classics on video, Documentaries, etc.) Labs Schedule labs in campus computing centers for exercises supporting classroom discussion. Lunches and/or Labs Combine lunch and lab times for student and teacher flexibility. (Loop films to run and re-run)

    Slide 28:Tip #4: Engaging Quiet Students

    Breakout assignments Charge breakout groups with identifying fellow students that haven’t had as much opportunity to participate -- have them give group “readouts” as group’s video spokesperson “Distant Stars” Rotate remote point-persons for distributing handouts, collecting assignments, faxing sign-in sheet.

    Slide 29:Tip #5: Guest Presenters

    Invite colleagues or students from other schools to bridge into videoconference. Reserve a spot for public if attending Presentations - no lectures, please! 50% presentation 50% Q & A

    Slide 30:Tip #6: Pre-course Tools, Communications, and Assignments.

    Tools (Website with syllabus, class rules, readings, recommended URLs, etc.) Communications (E-mail, Listserv, ClassChat) Assignments

    Slide 31:PLAN “B” rolling blackouts, V.I.P. tours, construction crews, etc.

    Class needs to know what to do/where to go if connection goes down, one site is evacuated, or other unforeseen event. Supplemental Communications E-mail, Listserv, chat Website assignments Lab and Library work Break out sessions
