Learning Technologies Channel broadcasts live educational content
using RealMedia software over the Internet. The goal of the Digital
Audio Testbed (DAT) Project is to produce a distributed digital
audio-based Internet infrastructure that will support extension of
RealMedia connectivity over NASA's Learning Technologies Channel to
5,000 clients in schools across the nation. The NASA Glenn Learning
Technologies Project is a site on the DAT network, as well as a content

is broadcast over the DAT throughout the day, but is pre-empted
by live educational broadcasts. A schedule
of events is available at the Learning
Technologies Channel schedule. During popular NASA events,
such as launches and landings, servers may be accessed to capacity.
Current maximum capacity is for 2,300 streams. Email firstname.lastname@example.org

video stream is designed to work over a 28.8 Kbps modem. It has been
our experience that even fairly powerful machines on fast connections
can play streaming "live" video at about only five frames per second.
Our encoder is set for an optimized frame rate of 20 Kb. This translates
to about 1 to 3 frames per second at 320 by 240 pixels.
NASA Glenn Learning Technologies Project has also produced live
events that have been broadcast over the Digital Audio Testbed. A
description of the event and the RealVideo archive are provided below.

of NASA Glenn Research Center Facilities
to a special set of tours of the NASA Glenn Research Center in Cleveland,
OH. NASA Glenn Research Center's primary mission is aeropropulsion
research and technology and is NASA's Center of Excellence in turbomachinery.
We are committed to being "World Class" in providing advanced propulsion
and power technologies to the U.S. aeropropulsion and aerospace industry.
Our ongoing research supports the nation's goals to develop quieter,
cleaner, and safer airplanes. The technology is transferred to the
aviation industry to help maintain U.S. leadership in the world's
aviation market. Tomorrow's passenger aircraft will have even better
fuel efficiency and more advanced systems than the current state-of-the-art
airliners. This presentation is a tour of three of our facilities.
For more background information on the tour please visit the Virtual
Tour web site.
to Aerodynamics demonstrates how 9th-12th grade math and physics teachers
can use basic aerodynamic theories incorporated into interactive lessons,
to enhance classroom instruction. This workshop utilizes the Beginner's
Guide to Aerodynamics to provide background information on basic aerodynamics
and propulsion. The Beginner's Guide to Aerodynamics is an on-line,
living textbook created by the NASA Glenn Learning Technologies
to FoilSim demonstrate how to supplement existing high school curriculum
with a free interactive simulation software package. FoilSim determines
the airflow around various shapes of airfoils. Students change the
position and shape of the wing by moving slider controls that vary
the parameters of airspeed, altitude, angle of attack, thickness and
curvature of the airfoil, and size of the wing area. The software
displays plots of pressure or airspeed above and below the airfoil
surface. The software calculates the lift of the airfoils, allowing
students to learn the factors that influence lift. For more information
on FoilSim or to download the FoilSim software, please visit the FoilSim
9, 1998 Turning Goals Into Reality: Web Cast and Chat
Aeronautics and Space Transportation Technology Enterprise held its
inaugural "Turning Goals into Reality" conference at NASA Glenn Research
Center in Cleveland, OH. The Learning Technologies Project cybercast
this event live and had a chat room open so that questions could be
asked to the speaker's from around the nation. You can follow along
as key government and industry representatives discuss critical issues
in our Nation's aviation and space transportation systems. It is a
chance for educators, students, and the general public, to find out
real-time what is happening in NASA's programs, how the results will
affect their lives, and what the future might bring.
