Wikispaces.com is now offering free wikis to higher education. When they launched more than five years ago, they announced plans to make 100,000 of their wikis ad-free and private, load them up with extra features and then give them away to K-12 educators. That went so well, they decided to give away 250,000 more. And they kept going.
I have used Wikispaces for wikis a number of times. One example is the End of the Essay wiki I created for a podcast series that I helped Dr. Norbert Elliot put together at NJIT. I have also had students create wikis as projects using the site.
According to their blog, they have given away 980,000+ free classroom wikis for K-12 education, and now they are extending their commitment to give away 2 million total free wikis for education. The features in these free educational wikis normally cost $50 per year, but are completely free when used for K-12 or higher education.
Teachers, students, professors, researchers, librarians — anyone can use their wikis in K-20 education. If your wiki will be used exclusively in higher education, you're eligible for one of the Higher Education plan wikis. On this complimentary plan, you’ll get a free wiki with more complete privacy settings, our User Creator tool to create student accounts in bulk, and other great features.

If your wiki will be used exclusively for primary and secondary education, those wikis are free and ad-free, and you can make them private. You can also open student accounts in bulk — without student email addresses. Create a free K-12 plan wiki
