Review of CMC
Key Terms in CMC
• Computer Mediated Communication (CMC)
• Asynchronous Communication
• Synchronous Communication (“real time” or “live”)
• Electronic Mail Systems (which can be further classified as push
or pull systems)
• Threaded Discussion Forums (can also be classified as
push or pull systems)
Steffen, Colleen, Tammie, Crystal
Types of Asynchronous CMC systems
•Electronic Pen pals (interpersonal communication)
•Individual and Cooperative Research Projects (gather
and/or share information from and with on-line
sources)
•Electronic Mentoring (on-line subject matter experts)
•Parallel Problem Solving (remote classes working on
similar problem sets)
•Electronic Field Trips (e.g. Virtual Field Trips via the
WWW)
•Group Development of Products (e.g. chain letters,
stories, scripts, multimedia constructions)
•Social Action Projects (e.g. peace projects, social
issues)
Steffen, Colleen, Tammie, Crystal
Types of Synchronous CMC Systems
a) Online Chat
•plain text chat(one to one)
•plain text chat (one or many to many)
•audio chat (one to one)
•audio chat (one to many)
•ability to moderate, lead discussions through
technological methods
•shared whiteboards / multimedia capabilities
Steffen, Colleen, Tammie, Crystal
b) Multi-User Dimension (MUD) and
Multi-Object Oriented (MOO)
•living verbal environments - you can become
anything you want (or not)

Virtual Environments and Virtual Reality
Attributes of Virtual Environments:
•Computer-generated representations of real or imaginary environments;
Experienced as three-dimensional via a number of senses - visual, aural
and/or tactile;
•Objects within these environments are independent of the user and can
display real world behavior;
•The user or users have autonomous control - the freedom to navigate
and interact with objects, using a number of different viewpoints;
•Interaction occurs in real-time; and the users experience feelings of
presence and/or immersion.
Steffen, Colleen, Tammie, Crystal
Why Virtual Reality in Education?
VR makes it possible to:
•Visualize and manipulate things that you cannot see in the real
world
•Take on different perspectives
•Visualize 3D concepts
•Interact in real time
•Explore dangerous situations
•Present realistic or abstract scenarios
•Promote different learning styles and teaching methods

Immersive Virtual Reality: A Short Introduction
In immersive VR, the user becomes fully immersed in an artificial, threedimensional world that is completely generated by a computer.
The head-mounted display (HMD) was the first device providing its
wearer with an immersive experience. HMD houses two miniature
display screens and an optical system that channels the images from the
screens to the eyes, thereby, presenting a stereo view of a virtual world.
A motion tracker continuously measures the position and orientation of
the user's head and allows the image generating computer to adjust the
scene representation to the current view. As a result, the viewer can look
around and walk through the surrounding virtual environment.
Steffen, Colleen, Tammie, Crystal
A variety of input devices like data gloves, joysticks, and hand-held
wands allow the user to navigate through a virtual environment and to
interact with virtual objects. Directional sound, tactile and force feedback
devices, voice recognition and other technologies are being employed to
enrich the immersive experience and to create more "sensualized"
interfaces.
Steffen, Colleen, Tammie, Crystal
Characteristics of Immersive VR
The unique characteristics of immersive virtual reality can be
summarized as follows:
• Head-referenced viewing provides a natural interface for the navigation in
three-dimensional space and allows for look-around, walk-around, and flythrough capabilities in virtual environments.
• Stereoscopic viewing enhances the perception of depth and the sense of
space.
• The virtual world is presented in full scale and relates properly to the
human size.
• Realistic interactions with virtual objects via data glove and similar
devices allow for manipulation, operation, and control of virtual worlds.
• The convincing illusion of being fully immersed in an artificial world can
be enhanced by auditory, haptic, and other non-visual technologies.
• Networked applications allow for shared virtual environments

Nunavut Distributive Learning - past
Baffin Divisional Board of Education more than 10 years
ago invested in First Class BBS service to link all schools in
the division.
Apple Canada developed an Inuktitut font and
manufactured syllabic and English keyboards. Provided
lots of equipment and resources.
CSILE (Computer Supported Intentional Learning
Environments) functions as a “collaborative learning
environment” and a communal database, with both text and
graphics capabilities.This networked multimedia
environment lets students generate “nodes” containing an
idea or piece of information relevant to the topic understudy.
Developed by OISE (Ontario Institute for Studies in
Education).

Nunavut Distributive Learning - future
The Nunavut Department of Education is committed to
developing online and CD-ROM based curriculum
materials in both English and Inuktitut.
These project need to be expanded to include more than
one dialect of Inuktitut. There are presently at least three
dialects used in the different regions.
Distribution will become easier as access becomes reality.
