WIKI 
The best way to fully understand the potential of weblog as a teaching and learning tool is to become a blogger.posting on other people`s blogs before you can start your own is a great way to get the feel of publishing your thoughts, just wait until that first person responds to something you`ve written. That’s when you will truly start to understand the power of the read/write web.

The more documentation and back up you have from students, parents and administrations in terms of clarifying the use of the tool the better it will be. When overseeing student blogs, the teacher's role becomes that of connector, not just evaluator. As you read what students write, try to respond by commenting back when appropriate. And link to the best student posts and ideas in the class blog.

Finally, you may want to consider giving each student his or her own blog. But before you do, make sure you and your students are totally comfortable with the technology and with the concept of reading and working Online.

Although I believe that allowing students to personalize their spaces makes them more invested in their blogs, I also feel that it makes the assessment more difficult.

Wikis pose some pedagogical challenges as well. They can be so effective at fostering collaboration that the teacher really needs to carefully examine her role in their use. As I noted previously, early, implementations of wikis in educational settings have shown that the more autonomy teachers give to students in terms of negotiating the scope and quality of the content they are creating, the better. It's a very democratic process of knowledge creation.Or how about doing a book study on a wiki? That's what Georgia teacher Shelley Paul did when her students read Turn Homeward. Hannalee by Patricia Beatty (tinyurl.com/36sy57). The class wiki has all sorts of student created content that gives context to the work, everything from interviews with storytellers, to presentations about local mills that are similar to those in the story, to all sorts of reference pages that explain parts of the text. The whole site provides a great deal of information that others can use in the study of the book.

Creating your wiki is as easy as filling in the form on the page linked above, a process that takes maybe 45 seconds if you're a fast typist. (A minute if not.) Enter a username, a password, and a working e-mail address, click the "yes" button to make a wiki, give your wiki a name (no spaces allowed, by the way), select the type of wiki you want (most educators pick "protected" to start), click the box to certify that you're using it for educational purposes, and you're up and running. All you need to do is click the "Edit This Page" icon when your wiki site appears and you can start creating the content on your site.

Regardless of how educators feel about the potential of wikis, and I can understand the hesitancy many teachers feel, one thing remains certain: The collaborative environment that wikis facilitate can teach students much about how to work with others, how to create community, and how to operate in a world where the creation of knowledge and information is more and more becoming a group effort
