A Wiki is a collaborative space where a group of people can create and edit information.  Wikipedia is an example of this where billions of users from around the world collaborate on various articles.

You can make your own Wiki for a class or subject area.  Perhaps a collaborative Wiki on a revision topic.

There are a number of websites which allow you to create a Wiki.  One example would be PBWorks.

Here is a link to access PBWorks where you can set up a free space (choose 'Get Started' and then 'Basic').  Below is a tutorial to help you get started:

Wallwisher is one of a number of online idea walls which can be used to collaborate.  You can create a wall and then email a link to your students.  They then share their ideas by creating notes.  These look like post it notes and at their most basic level include text.  You can however also link to images, video, audio and websites to expand on the ideas provided.

There are other clear uses for this tool including demonstrating work, peer
