Wiki for e- learning! Why?

Why use wiki for e-learning week? Why not use other e-learning platforms like blogs, discussion forum, podcast or...?  I suppose the choice of tool that one uses depends on one's content and purpose. Unlike blogs and those mentioned, wiki allows collaboration within the targetted comunity of learners. This idea is certainly great if it's used for a particular project/discussion that is to be done within a limited period of time (like the e-learning week) and learners just need to focus on one particular page and build on one another's idea. However the organisation of the content  and instruction that follows, is very important. Users need to know first the features of  a wiki to be able to utilise it confidently. Once they are confident, they will be able to understand the instructions given on the frontpage of the wiki used and intended objectives of the author of the wiki may be achieved.

Nowadays, quite a number of educators use wiki for e-learning purposes; for content enrichment in blended learning or for compiling learners' work saved in pages created in wiki itself. Authors/ administrators can lock these pages and ensure that only the assigned individual or group members can access it and make changes. For a group task, the members in the group can work on the page assigned to them wherever they are as long as they can access the internet. This feature would be very useful for formative assessment too.

I am one those going-to-be avid users of wiki because I'm working on on-line blended learning with wiki and i find that it's the best tool for my content and purpose. However, there are few areas that I am not comfortable with wiki-the layout. It is very rigid and lacks aesthetic. It's too functional and structured (yes.. I agree that's what wiki is intended to be)and ... linear. One has to scroll down the page to see the last word of the page..urgh!
