Activity 1.3 – Communication Technologies

Synchronous versus Asynchronous

Synchronous

What is synchronous communication? Provide examples:

A real-time, instructor-led online learning event in which all participants are logged on at the same time and communicate directly with each other. In this virtual classroom setting, the instructor maintains control of the class, with the ability to “call on” participants. In most platforms, students and teachers can use a whiteboard to see work in progress and share knowledge. Interaction may also occur via audio- or videoconferencing, Internet telephony, or two-way live broadcasts. (http://www.learningcircuits.org/glossary)

What is the benefit of synchronous communication?

The benefit is the instant response between instructors and participants. This direct communication allows clarification of points raised and so on, on the spot. It also gets participants in the momentum to think about the topic discussed.

When would you use it?

Perhaps you would use this to replace classroom settings. Also for any collaborative work that needs to be done.

Asynchronous

What is asynchronous communication? Provide examples:

Learning in which interaction between instructors and students occurs intermittently with a time delay. Examples are self-paced courses taken via the Internet or CD-ROM, Q&A mentoring, online discussion groups, and email. (http://www.learningcircuits.org/glossary)

What is the benefit of asynchronous communication?

It allows the participants to work at their own pace. Also allows for time to reflect on issues and to conduct independent research.

When would you use it?

I think it would be appropriate in settings where the student is engaged in with other commitments and so needs to work in their own time.

Current trends in e-Learning are indicating that effective learning can be enhanced through the use of these communication techniques. What do you think are some of the drivers in the current environment?

I believe the main driver of these communication techniques is the fact that distance is a major barrier to communicating effectively and with these technological infrastructures they aren’t just a means of communication but a support system in encouraging communication and the expression of ideas. Furthermore, the anywhere anytime aspect is becoming more and more appealing to learners as we all have busy lives and various commitments that aren’t as flexible as synchronous and asynchronous communication.

The use of asynchronous technologies has been widely ignored as an appropriate method for enhancing learning through collaboration of learners.

Gilly Salmon’s Computer-Mediated Conferencing (CMC) Model (2000) however, now provides the e-moderator or facilitator a structured process through the use of e-Tivities to create meaningful learning activities.

The diagram above outlines Gilly Salmon’s 5-stage CMC model. (Salmon,G. 2000, e-Moderating, Kogan Page, UK)

Follow the link below for an interactive explanation of the model:

The interactive feature of this site is very well designed. It is very simple and straightforward with its explanations that are sequenced in a logical order.
