For my Year 13 English class I have created a wiki which provides ongoing support and extension. One way you can use the wiki effectively is to provide students with electronic versions of grids which guide them through a number of readings, you can also provide them with live links to a number of sites you have preselected (thus saving time and photocopying).
Check out the link below to see how I have used this process to encourage my Year 13's to look at what the critics say about Richard III and to encourage them to then draw their own conclusions.
