This is the site of a Middle school teacher who created a class project about genetic disorders using Wikispaces.
In the homepage she has the learning objectives, dates to remember, project rubric, requirements of the project, and the list of items to be researched and presented in class.
The neatest thing is that she made her students sign to agree with the rules of the wiki project.
It is a good model for projects in Middle school.
