SHOW
& TELL: ONLINE LECTURE OPTIONS

For
anyone considering some form of online lecture or presentation, the problem is
trying to replicate the ÒpresenceÓ you take for granted in a face-to-face (F2F)
setting. There are many options, but you need to understand their pros &
cons to choose wisely.
Key
Terms & Concepts
á
File
size: How big will the resulting file be for your end users? You can record
audio narration in PowerPoint, but the large file size will be difficult for
your online users to view and/or download.

File
formats (good resource: http://all-streaming-media.com)

Stream
vs. Download vs. Podcast: If you want users to view (but not have) your
presentation, you likely want to stream it by providing a link that displays
the presentation, usually on some form of a web page that users view on a computer
with active Internet connection. A straight file download lets users Òtake itÓ
with them, but still requires a computer. A podcast can be viewed and listened
to on a computer OR an MP3 player like an iPod, but MP3 player screens are so
small, most people treat podcasts like Òradio.Ó
á
Production:
Ease of use vs. flexibility & dependency: Getting someone to tape &
publish whatever you present or say in class is definitely the easiest means of
production, but you may have to plan (and pay) accordingly. Screen capture
tools like Camtasia let you record and publish whenever the spirit moves you,
but may take some time to learn.
á
Synchronous
(real-time) vs Asynchronous (not in real-time): A live online chat using
Horizon Wimba can feel more natural, but how many voices can you manage at one
time. Canned presentations may be less authentic, but are easier to publish and
distribute online.
á
Narrated
Presentations vs. Screen Captures (or ÒscreencastsÓ): Do you just want to add
voice to an existing presentation or be able to capture and narrate anything
you can see on your computer screen? You can do both in a more or less ÒlinearÓ
fashion where hit ÒrecordÓ and speak over what you present or display and then
eventually produce. You can mix and match presentations and captures, but then
this introduces more advanced editing needs.
Solutions
for Recording & Editing
Recorded
Audio in PowerPoint
Great
because it's free, but student pays the cost in file size download. Just ask
Carolyn Seaman in information systems who has gone this route for her online IS
grad classes, and is refining her approach. Carolyn's done a LOT of advance
work recording her lectures, and gets good reviews from students, but also is
looking for a better way to reduce file size. Last we talked to her, she seemed
to be leaning toward Camtasia or (possibly) Wimba's "Live Classroom,"
which we've been piloting all year.

Great
because the file is "streamed" which means it's quick & easy for
students to view, and you can record anything (including PowerPoint or anything
on your screen). But it can only be played back in the Wimba environment, which
may be a turnoff for some faculty who invest a lot of time into the online
lecture process. The expert to consult is Marie Deverneil in MLL.
Profcast
(www.profcast.com)
This is
a new tool ($30) that seems be banking a lot on lectures as podcasts in
general, and Apple's new iTunesU specifically. There's a lot of merit to
considering online lectures more as radio broadcasts, particularly if portable,
repeatable playback by students is a desirable pedagogical strategy. They're
probably not watching videos (let alone talking head lectures) when they're
working out or commuting, but maybe they can do these and other activities
while listening to your lecture. Downside: Mac-only.
Snapkast
(www.snapkast.com)
This
seems to be exactly like ProfCast, but it works for the PC ($30).
Camtasia
(www.techsmith.com)
OIT
likes this for both narrated screen captures and powerpoints and the ease of
producing as flash files, which are ideal for Blackboard and any other Web
delivery. But this is a PC-only solution, and a very good alternative is
Macromedia Captivate, which works on both PC and Mac. We find Captivate to be
more full featured than Camtasia, which takes a little more time to master and
figure out when youÕre in a hurry. But we just haven't put enough time into
Captivate. Academic price: $179 (but get the bundle with SnagIt for a total of
$199). Tip: you can download and use a 30-day trial version.
Note:
Jing, is a free (for now)
screencast capture tool made by TechSmith.com, which also makes Camtasia. If you just want to make short
(5 minute) "quick & dirty" narrated screen captures and
"mini-presentations," this is a great tool.
Here's
an example from the Maryland Blackboard Users
Group (MDBUG) Conference
Adobe
Captivate (www.adobe.com/captivate)
This
product used to be called RoboDemo and has been a staple for online tutorials
and training for many years. It's nice that it works on both Mac and PC, but it
takes a little longer to distinguish the essential features from the desirable
ones (compared to Camtasia). One plus about Captivate is that you can easily
annotate screen captures with text labels and callouts (or bubbles). Captivate
will even do a lot of this automatically.
Publishing
However
you create your online video or lecture, you should seriously think about
publishing it on UMBCÕs new iTunesU server (http://itunes.umbc.edu).
This works just like the regular iTunes your students use all the time, but is
dedicated for academic content posted by colleges and universities. For now,
UMBCÕs iTunesU does not require the use of UMBCÕs userid & password, but we
expect to have that implemented by Fall 2007 (while still retaining a ÒpublicÓ
UMBC iTunesU version that anyone can access). After we have the ÒauthenticatedÓ
UMBC iTunesU available, we will be able to ÒmapÓ or synchronize your iTunesU
lectures with your UMBC Blackboard course and student enrollment.
