Technology, and Operations

Distance and asynchronous learning are important topics in both industry
and academia. Many educators and technologists developing distance
learning programs are unfamiliar with previous research and experimental
results in pedagogy, technology, and operations related to distributed
collaboration and distance learning. Distance learning began over a
hundred years ago with correspondence courses. The introduction of
television and video conferencing technology created new opportunities
for delivering education. More recently, the development of desktop
collaboration tools (e.g., CuSeeMe, the H.32x standards,
Webx, the Mbone tools, and NetMeeting) and Internet webcasting technology
(e.g., Quicktime Streaming, Real Networks G2, and Microsoft Windows Media)
provide more alternatives for educational delivery.
Many universities and companies are using these technologies
to deliver remote instruction, but questions remain about educational
effectiveness and costs.
This tutorial presented a broad introduction and survey of many topics
in distance learning ranging from pedagogy to technology including
studio classroom design, collaboration tools, and operational issues.
The tutorial was divided into the following sessions:
- Introduction and Background [pdf]
-
The first session discussed the history of higher education beginning
in ancient Greece around the fourth century BCE and
continuing through the development of the modern
university in the eleventh century ACE to the situation today.
The basic form of higher education today is discussed and various
technologies that have impacted the current educational environment
including the development of distance learning programs over 100 years ago.
- Education and Pedagogy Issues [pdf]
-
The second session covered past results from deploying distance
and asynchronous learning technologies.
Learn why "sage on the stage" is a discredited approach
from a pedagogical perspective and why "tutored video tape" has proven
successful in many experiments. In addition, the session covered successful
synchronous distance learning strategies that use televsion and
video conferencing technologies.
- Equipment, Facilities, and Transmission
[pdf]
-
The third session covered classroom design and cost.
The basic equipment needed to produce video conferences and webcasts is
described and solutions to common problems are discussed. The development of a
well-designed studio classroom with cameras, microphones, multimedia
presentation equipment (e.g., projectors, document cameras, VCR's, etc.)
is difficult and can be very costly. Different classroom designs are
described and compared.
- Collaboration Technologies [pdf]
-
The fourth session covered the basic technology for distance learning.
Different technologies are described and compared including support
for audio/video interaction, whiteboard and multimedia presentations, and
other collaboration tools (e.g., chat rooms, media spaces, etc.). Specific
examples covered include H.32x standards, the Internet Mbone tools,
and streaming media technologies. Tools for producing live collaborations
and for producing rich multimedia material for on-demand replay are
discussed including emerging multimedia standards (e.g., SMIL) and lecture
browser technologies.
Finally, operational issues of producing distance and asynchronous learning
classes are discussed including program guides, equipment and labor
costs, and operational procedures.
The Berkeley Internet
Broadcasting System developed to webcast class lectures for live
viewing and on-demand replay is used as an example.
- Future Vision and Research [pdf]
-
The last session covered some thoughts about the difficulty of predicting
the future and problems that must be addressed in distibuted just-in-time
learning.
