Look for more photos coming later today from the wonderful videoconferences from author James Otis Thach live at Cooperating School Districts! We thought this image was too great not to share right away. This is Kelsey, a young viewer from Texas. She, like the other children connecting to today’s VCs, learned from James how he became a writer, who and what influenced him, and heard him share the first chapter of his book, The Seal Pup. We will have a link to an archived session of his morning videoconferences by tomorrow- and we will definitely share it!

Cooperating School Districts’ distance learning program, New Links, is pleased to announce the return of author James Otis Thach for a few videoconferences- and a live stream of the morning events (courtesy of MOREnet)- tomorrow at both 9 and 10:30.
James is a Missouri native and the author of A Child’s Guide to Common Household Monsters, The Tickle Monster is Coming and his latest, The Seal Pup. This will be the fourth time James has videoconferenced live from CSD; he will read from his book, The Seal Pup. The story follows the quest of a lone seal, trying to reunite with his herd. James will also talk about the true story than inspired the book, and about the long journey of making a book. James will also share related videos, and invite the kids to use their research and library skills to find the documentary the book is based upon. This event’s target audience is elementary students.
Click here 10 minutes prior to the event to access the live stream. It is suggested you test your players using the Test Stream option at the top of that page prior to logging on for the event. Thanks to James Otis Thach and MOREnet for helping bring this event to students everywhere! Questions? Contact New Links Program Coordinator Rebecca Morrison.

I was reading Janine Lim’s blog, Videoconferencing Out on a Lim (see our blogroll) and came across a post entitled: A Little VC Technical Knowledge. I’d like to share an excerpt from her post with you- it’s very good, basic information for those interested in videoconferencing. For those of us who are “videoconferencing veterans” it’s good to read & remember what can trip people up as they start out. Thanks, Janine, for taking the time to put this together. To read her full post, click here.
“Some basic concepts (written in my [Janine's] lay language!) include:
- IP numbers that start with 10. are internal addresses and people outside can’t call them.
- Most videoconferences are at 384K. Compare that to the amount of available bandwidth on a typical day to know if you’ll be able to sustain a “good enough” videoconference.
- Packets are little pieces of info sent over the network. In email the packets eventually get there, get together, and give you an email. But in VC, if the packets don’t show up in time, they get thrown away. Hence, packet loss. Usually 2% packet loss or higher becomes intolerable.
- A NAT is network address translation, and both the codec/endpoint and the firewall/router need matching settings for NAT to work. This is because the endpoint/codec needs that info to set up the packets properly.
- An IP videoconference call is set up on port 1720. After that the two codecs negotiate which ports to use for the audio and video streaming. This is what’s going on when it rings & rings.
- If you’re using a gatekeeper, ports 1718 and 1719 are used to find and register with the gatekeeper. More on ports here.
- Two great resources to learn more about H323 and your network are: H323 and Firewalls from MOREnet in MO; and UKERNA/Janet Security Guide for H323 from the UK.”

RoundTrips is happy to invite your students to join them, the Missouri Department of Transportation, and MOREnet for “Bridge Construction 2: Surface Structure” on April 17 at 9:00 a.m. and 10:00 a.m. Central Daylight Time. This free program, the seventh in their ten part series of videoconferences highlighting MODOT’s construction of a new bridge over the Missouri River at Glasgow, Missouri, will focus on the work involved with creating the surface structure of the new bridge. More information about the entire series of bridge programs can be found at http://mobridge.more.net.
If you have any questions about the program, please don’t hesitate to get in touch with RoundTrips. If you’d like to enroll for the program, please contact them via phone or e-mail.
Bridge Construction 2: Surface Structure
Date: April 17, 2009 | Grade Levels: 5-12
Times: 9 to 9:50 a.m. and 10 to 10:50 a.m. Central Time
Cost: No Fee
The bridge has been designed, public hearings have been held, and funding has been arranged. Construction is well underway with superstructure built for the bridge’s approach ramps and additional superstructure being built over the river itself. Now it is time to begin creating the surface structure. Join us live from the construction site of the new bridge going over the Missouri River at Glasgow, Missouri.
What are the steps in creating the surface structure? What materials are used? How is the structure welded together? How is the surface structure for the bridge connected to the bridge support system? What elements are pre-fabricated and what is created on site? How does the installation occur? What are the careers involved in building a bridge? For the answers to these and other questions, join RoundTrips for our sixth program in our continuing series of programs produced with the Missouri Department of Transportation as they build a new bridge over the Missouri River at Glasgow, Missouri. Interact with construction personnel as they share how they are bringing the design plans to life.
