I tend to think of wikis more as actual websites compared to weebly or blog websites. Wikis are great resources for group work as well as individual work for students. It allows them to colloborate when nessicary as well as work on the project from virtually anywhere. Wikis are also very user friendly and allow work to be divied well, for instance each person could be repsonsible for a page.The students are also learning authentically as they create the page, by determining what is necessary information as well as how to organize it.
One of the most important features of a wiki is the history feature of it. It is essential to be able to view the history and edit changed made for the product to be successful. The history tool is also a great resource for te teacher to monitor student accountability and contribution.
I also like that the teacher can grade and monitor the wikis from anywhere and throughout the whole creation process. The wikis are also great becasue it gives the students ownership and the feeling of real accomplishment when they are done. One last great feature is that the information can be shared with grandparents and aunts and uncles, etc. anywhere, as long as they have access to the internet!
