Recently, Lafayette High School in the Rockwood School District participated in Baikonur and the Soviet Space Race, offered by the Inner Asian & Uralic National Resource Center.
This free videoconference attempts to fill in the gaps in our understanding of the Space Race, as seen from the other side: namely, the Soviet Union. The content provider looks at both their successes and failures, as well as the modern reality of the Russian space program being located in the independent country of Kazakhstan.
I’d like to share some feedback I got from the school on this interactive videoconference from the Inner Asian & Uralic National Resource Center:
Our interaction today was one of the most educationally engaging and valuable that our school (read that, 48 videoconferences last year) has participated in. Your “product knowledge” was extensive and complex, and, truly, we would LOVE to spend another hour discussing this topic with you. As videoconference planner, I try so very hard to locate conference experiences of relevance and quality, such that the deviation from class lesson is no deviation but enrichment, and, wow, this presentation was off the charts. Thank you, sincerely, and thoroughly. If you could really speak with us again, please let us know. We don’t want to overextend our welcome, but, you and the information and passion you shared are the rare real deal.

Are you new to videoconferencing (Skype or H323?) Do you want to improve your support of videoconferencing in your school?
Consider taking one of Berrien Regional Education Service Agency’s online classes. Berrien RESA is an education service agency in southwest Michigan. Interested in the classes? Note that videoconference assignments are included in both classes. Click on the class titles to get more information about the course:
- Planning Interactive Curriculum Connections, October 5-30, 2009
- Kid2Kid Videoconference Connections, November 2–December 18, 2009 (Thanksgiving week off)
Explosive New Videoconference from RoundTrips! Tuesday, September 8, 2009

Join RoundTrips live on Friday, October 9 from Rolla, and Macon Missouri. Be part of the action as explosives expert Dr. Paul Worsey (Professor of Mining Engineering, Missouri S&T) and engineers Dennis Brucks and Brian Haeffner from Missouri Department of Transportation walk us through the process of bringing down the Glasgow Bridge.
As part of its continual work to maintain and upgrade Missouri’s roads and bridges the Missouri Department of Transportation determined the need to replace the bridge crossing the Missouri River at Glasgow, Missouri. That new bridge is now set to open on October 16, but before that new bridge could be built, the old bridge needed to be removed to make way for construction of a new span connecting route 240 across the Missouri River. In this program your students will interact with the engineers who will give us technical aspects of the destruction and rebuilding of the bridge. Ask your questions about what it takes to safely destroy one bridge so you can begin to build another. You’ll see video excerpts of the bridge coming down, and explosives demonstrations by Dr. Worsey.
This program is the ninth of an ongoing series of ten programs that began during the 2008-2009 school year. It is 10/9/2009 at 9:00 AM – 10:00 AM and 10:30 AM – 11:30 AM. Register by October 2.
During this series of programs entitled Project MO-Bridge: Connecting Students to Their Future, your students will be able to learn what it takes to build a new bridge—from dream to design to construction to operation. Students will interact with experts in a wide variety of fields and learn how specific aspects of their science, social studies, and mathematics curriculum come to life in the construction of a new bridge. Archived versions of previous programs can be found at http://mobridge.more.net.
Internal IP, Packet Loss, Endpoints, Oh My! Tuesday, July 14, 2009

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.”



Cooperating School Districts of Greater St. Louis has a partnership with The Princeton Review to bring inexpensive, quality ACT prep to students through distance learning. For just $140, a student gets three practice tests, 20 hours of interactive instruction over videoconference and access to online resources from The Princeton Review. 
St. Louis author and New Links to New Learning content provider Amy Sklansky is working on new videoconference offerings for the 2009-2010 school year!
