Video-Lectures over Internet - E-Infrastructures and Technologies for Lifelong Learning - page 267

REFERENCES physically attend lectures, video lectures are in

fact used by traditional students as an additional
tool that allows them to quickly find informa-
tion or to review their understanding. Moreover,
video-lectures can be creatively used to change
the didactic paradigm. Even more importantly,
they start creating a body of knowledge that can
be extremely useful for informal self-study, hence
supporting the life-long learning perspective.
Although some basic problems have been
solved and tools for producing and distributing
video-lectures are available in various forms, a
standard has not yet emerged (and might be useful
in future to allow interoperability of tools that will
mine and extract information from the lectures).
Several research directions have fruitfully
produced results in various areas such as improv-
ing the automatic capture of lectures and events
connected with them, even though there is ample
space for improving the results obtained so far.
The market and technology of portable small
devices is still evolving, and for sure we shall in
future see more attempts to bring (video)lectures
on them: much has still to be done in terms of
usability for these devices, and also to ascertain
the actual usefulness of bringing these resources
on small devices.
The marriage of Web 2.0 and video-based
education is still not complete, and probably we
shall see future development in connecting virtual
(learning) communities and video-lectures. Social
annotations may be one of the ingredients.
Finally, we believe that better support to search
and intelligent navigation of multimedia content,
probably based to more advanced semantic ex-
traction, will be the main front on which further
research will improve usability and usefulness
of the video-lectures. This last fact is especially
necessary and useful for providing a better support
to life-long learners.
