Wikis enable anyone and everyone to create content online using easily understandable tools. The most famous wiki is wikipedia.
Wikipedia is a free internet encyclopedia. Of course there are many advantages of Wikipedia but also there are disadvantages of it. One of the disadvantages is if the information which is in it is realiable or not. Anyone who wants to add some information can add it. These information may not be true.
The teacher can use wikis in classrooms. The teacher can have his/her students use a wiki to publish information about a topic that they are investigating. Thanks to wiki, we can create collaboration opportunities between classes across the school and across the world.
And also with PBWorks, in classrooms we can do class resources, group projects, student porfolios .
