Educational uses for Rev

Thu Aug 12 18:43:57 EDT 2004

Hi Gregory,

Thanks for your interesting posting, and to everyone else who has 
contributed to this thread

I've been involved in developing educational media software for over 10 
years, at a University here in NZ until a few years ago when I went out 
on my own.  A lot of my early work was in the area of computer assisted 
learning, using HyperCard.  Later I branched out into other academic 
disciplines, particularly medical teaching. I'm also convinced of the 
potential of applications like Revolution to contribute to meaningful, 
constructivist, student-centred online learning spaces.

Over the last two years I've been trying to put these ideas into 
practice in a commercial form.  I've just released the results of this 
work, an application called OceanBrowser (PC/OSX) to my first 
customers. Developed in Revolution it combines a set of learning 
objects, a backend database on the internet for collaborative data, and 
a content management system for course data distributed on CD-ROM.  
It's designed to allow people to start out with what they have and feel 
comfortable with, and to gradually increase the interactivity/scope of 
learning activities as time and resources allow.  It's important to the 
business model that the software is practical out of the box.

For those of you who are interested in the detail of the current 
product, here's a little more information.  My initial customers are 
all involved in online postgraduate medical education.  They have a 
well defined set of requirements, which include the ability to work 
with complex multimedia such as VR movies, audio, and large numbers of 
high resolution images.  They also have a lot of documents that need 
distribution, typically Acrobat documents and Powerpoints.  We 
converted the latter to Flash in order to more seamlessly display them 
in OceanBrowser.   The product uses Altuit's excellent Altbrowser dll 
(on the Windows platform) to show web content.  OceanBrowser supports a 
custom protocol ("ocb://") which allows academics to embed links in web 
pages or emails to point to specific learning resources in 
OceanBrowser.  When the student clicks on this link, OceanBrowser will 
open, retrieve the resource (typically from a database stored on the 
local computer) and display.  Next to every resource displayed in the 
system is a comments area that "tracks" the content being showed.  
Users can post comments to this area, which may also embed appropriate 
metadata (e.g. posting to an audio item includes link to the timepoint 
the user was at in the audio file, posting to Flash powerpoint links to 
slide).  "Resource" can be anything ranging form a document (pdf, 
webpage), multimedia (image, movie) to an application (Flash player, 
Director projector, etc).  The foregoing list may seem to be overly 
orientated around document distribution, as I said though, my users 
have a large body of existing content they need to work with, so stage 
one is to address these problems.

One of the more interesting learning objects in the system at the 
moment is an image annotation tool, which allows the user to view or 
create multimedia annotations to an image (by drawing a region on the 
image, recording an audio commentary, and providing additional 
information such as name, description etc).  This has been based on 
some research I've been doing over the last year or so, and I hope to 
extend these annotation features to support true, distributed, 
collaborative image annotation.

With OceanBrowser I'm hoping that by creating a sustainable business 
model I'll be able to afford to invest the time into interaction 
design, prototyping, and research (review of educational 
literature/other products) that will be required to implement some of 
the more exciting educational ideas that I want to see in the product 
over time.

The new website for Oceanbrowser.com will be going up in a couple of 
weeks, now that the software product is complete.  I hope then that we 
can put some demo content up for everyone to have a look at.

Regards,

Rodney
