Collaborative

Wikispaces
This is a free site for hosting a "wiki" page. Wiki sites allow multiple persons to collaborate using the same web space. Wikipedia is the most popular example. For classrooms, wikis have been used by students in the same school or in different states and countries to collaborate on all kinds of projects. A great feature for classroom use is that a history is kept for each page: old files can be retrieved, and the contributions of each contributor can be tracked ---so in group projects, the teacher can identify who did what. Free classroom wikis are available for K-12 teachers.

Google Sites
Google tool that allows you to create free webpages/wiki sites. Students can work on projects together as co-editors of an easy to use wiki site.

Bubbl
A free mindmapping site. Users create a name and password and then have access to a mindmapping tool. Multiple users can collaborate on the same site. Products can be embedded on websites and into other software programs.
