In many distance education contexts, students can be separated
from their teachers and peer groups for long periods of time, and they can
experience feelings of isolation. Although students cannot meet face to face,
the use of computer based communication, can if used effectively, offset some
of the more negative aspects of studying alone.
Computer mediation of communications (CMC) can be achieved by the
use of networked computers. CMC is now being used by a growing number of
universities worldwide as a supplement to paper-based materials, audio and
video resources and the telephone, because it can incorporate the attributes of
each of these into one medium.
Collaborative Learning
CMC can be used to promote collaborative learning, particularly
for students who may be separated by distance of a geographical and/or time
nature. Collaborative learning is a term referring to the acquisition of
skills, knowledge and attitudes arising as a direct result of people working
together to explore, discuss and create meaning. Increasingly teachers are
seeing the benefits of collaborating through CMC, as it is an ideal medium for
both immediate dialogue development (synchronous or real time communication)
and time-shifted or asynchronous dialogue which allows time for reflection. The
following on-line article will help the reader to come to grips with the issues
involved in designing collaborative learning environments using networked
computers:
Because computer mediated communication heavily relies on text,
there is a problem of reduction in social cueing. For example, talking to a
fellow student without being able to hear the tone of their voice or the ever
present inflections as a person conveys meaning, can be problematic. People can
misconstrue intentions and may even get offended if they can't detect true
meaning! The study of presence
in cyberspace is an important area of work and the contribution of
John Suler to our understanding is highly recommended.
Although there is often an absence of para-linguistic content
normally present in face to face and even telephone conversations, CMC can
still provide an immensely rich communication platform for learners. Groups can
for instance, look back over an entire history of communication between
members. Cumulative records of conversations and collaborations (electronic
archives) on the computer can provide excellent material for reflection, in
depth analysis and evaluation. These records would not exist in such a complete
format through other communication media.
Many online communities develop their own rules and guidelines
(including systems of sanctions) to deal with
deviant behaviour and to protect users against the possible negative
effects of text based communication. Reduction of social cues can cause
misunderstandings that can result in users 'flaming' each other. This kind of
'net etiquette, or netiquette
varies, but serves to regulate online communication within an acceptable
framework of discourse.
The use of emoticons (smileys
and other non-verbal cues) are a prevalent use of the keyboard to convey
emotion and meaning in text only communication environments. A more in depth
examination of computer mediated communication and the reduction of social cues
is found within the article entitled:
Computer Mediated Communications by Rhona Magee and Steve Wheeler
(1997).
The Challenges
The advent of CMC presents a number of challenges to teachers. Development and
research is still needed to ascertain the full benefits of CMC, and how it can
be optimised in a varied number of learning contexts. CMC promotes group
interactions and is an excellent medium to encourage reflective learning, but
the task of incorporating CMC into every day education remains a difficult
proposition for many.
The On-line Journal of Computer
Mediated Communication is a useful resource and lively forum for
discussion about all aspects of CMC in education and training.
