Computer Mediated Communication

2. Computer Mediated Communication
• Computer-mediated communication (CMC) is defined as
any human communication that occurs through the use of
two or more electronic devices.

3. Computer Mediated Communication
• That communication takes
place through different
ways in the following
elements:
• Timing
• Number of participants
• Medium

4. Interpersonal communication Element
• Sender’s anonymity
• Receivers
• Channel
• Messages
• Feedback
• Context in CMC

5. CMC Types
Asynchronous (one-way)
• Voice mail or e-mail
Synchronous (two-way)
IM/chat/Telephone/Videophone, Skype,
Interactive multi-user games

6. Asynchronous
Electronic
Communication
Tools
Web Publishing
E-MailFaxing
Voice MailInstant Messaging

7. Feature of Asynchronous:
• Available anytime
• Available anyplace
• Variety of media
• Multiple perspective
• One to one or one to
many communication

8. Problems with asynchronous CMC?
• Posts to the discussion boards need to be frequent for
people to maintain an interest in the boards, and so if the
level participation drops below a certain degree, no further
postings take place.
• The asynchronous nature encourages people to give
participation a lower priority.
• Delay in communication occur in asynchronous CMC.

9. How can we solve these problems?
• Make the discussion time -dependent, so that participants
cannot late in participation .
• Cut and paste discussion threads that diverge or are
repeating discussions elsewhere, so that each thread
corresponds to one topic.

10. How can we solve these problems?
• Identify specific points within the threads to
prompt particular discussions, eliciting answers to
specific questions.

12. Feature of synchronous CMC:
• Immediate response
• Collaboration
• 1 to 1 communication
• Allow body language

13. Problems with synchronous CMC?
• Language difference between two
communicator create difficulties in
communication.
• Students on a slow connection always lag
slightly behind in the discussion.

14. Problems with synchronous CMC?
• The discussion tends to lose focus because of many
side discussions.
• Some students cannot jump in because they are slow
typists.
• Responses get out of sequence.

15. How can solve these problems :
• The solution to this is to have a prepared set of
questions, subjects to discuss, etc.
• Introduce some of the abbreviation and
emoticons used in chat to their less experienced
peers.
• In face-to-face one’s authority can be underlined
by raising one’s voice, in chat you can use
upper case to make your point more forcefully.

16. Which CMC should we use?
• “should the communication be synchronous or
asynchronous?”
• Are the participants part-time students/spread across time
zones?
• Is the subject matter one which requires in-depth analysis
and response? If so, then an asynchronous medium is most
appropriate.

18. Collaborative Work
Management Tools
Computer Mediated Communication tools?
Calendaring and
Scheduling
Task and Project Management
Workflow Systems
Document Sharing
Knowledge Management

19. Why use CMC tools?
• As the world flattens with increased
globalization, being able to
effectively communicate and
collaborate over distance has
become a critical skill.
