How I Use It
I use wikispaces every semester with my students. I create a main page with assignments, due dates, class procedures, and links to online resources and ones I've created. Then students create their own page on the wiki and it acts as both their digital hand in space and an online portfolio.
Very education friendly and easy to learn and use. It's easy to create a class website or to create a space only for student portfolios, homework, and great for creating an easy space to collaborate online. You have total control over who sees and edits the site and there are many features to explore if you wish or the simple things get you off to an easy start. These people get education!
