Disseminating & Accessing

Open Content

Open Content refers to an ideology that promotes free and accessible knowledge for everyone.

Mobile Devices

A mobile device is any easily portable device that can be used to access the Internet.


RSS stands for "Really Simple Syndication," and is essentially a means of "wrapping" files in a digital container so that users can subscribe to an online service. By subscribing to a service, the user will automatically receive an updated file (or a new "issue") every time one is produced. RSS can be used to deliver any kind of file: text, video, audio, etc.


A blog is essentially a kind of online journal, in which a user (or group of users) write about ideas or innovations of interest to a particular group. Most blogs have a "comment" feature, which allows readers to comment on a blogger's post.


A podcast is essentially a series of audio files that are delivered to a subscriber by means of a platform such as iTunes. Every time a new audio file is produced, it shows up in the subscriber's podcast platform.


Screencasting refers to a narrated video, in which the content of the video is primarily the screencaster's computer screen. In other words, you perform some action on your computer while describing it, and this is captured by a screencasting program. The resulting video can then be shared with others.

Personal Response Systems

Google Moderator can: Make it easier for shy students to ask questions Allow students to formulate and articulate their questions more clearly Allow an instructor to respond to the "best" questions Allow an instructor to see which questions are held by the greatest number of students  

Back Channel

The term "back channel" refers to communication in a classroom that occurs during a lecture, presentation, or discussion. The back channel can be disruptive (for example, if it has nothing to do with the class), but it can also be harnessed: it can be a way for students to share ideas, questions, and insights that pertain to whatever is "front and centre" in the classroom.


Wikis allow many people to write and edit a document collaboratively. Some wikis are asynchronous, meaning that when one user is working on a given document, other users are temporarily locked out of it. Other wikis strive to be synchronous, meaning that several users can be working on the document at the same time. Wikis can be an effective way of bringing together the knowledge and skills of many people, separated by distance.

Social Bookmarking

Social bookmarking platforms allow a user to do the following: save the location of any web resource annotate the saved web resource (e.g. summarize its importance) tag the saved web resource with relevant key words search a library of saved web resources by key word share a library of save web resources with others do all of the above from any location -- that is, the collection of web resources is saved online, and can be accessed anywhere

Web Conferencing

Web conferencing allows individuals separated by distance to meet virtually -- that is, to meet online. Web conferencing can be: audio only audio and video (via web cams) audio and video, with shared access to a drawing space or typing space

Online Discussion Forums

Online Discussion Forums (also known as Online Discussion Groups) are an effective way of providing information to students outside of class, but their real value lies in the opportunity they provide to allow students to share ideas with one another, and to respectfully challenge and build upon one another's ideas. Two documents that will help you foster effective online discussions are here:
