http://education.weebly.com provides teachers with the opportunity to give students their very own website. Teachers are able to create up to 40 student accounts for free, and they can have complete control over all the site the students create. Teachers also have the option of keeping the sites public or private. However, even if a site is private, students within the class can see each other's site.
I see real possibilities with Weebly. Students could use it in any subject area to report about their learning in a fun and exciting manner. Instead of using a reading journal, give them a Weebly site. Instead of having them turn in a worksheet about science vocabulary, have the students create a website with links, pictures, text, and videos about the terms they need to learn. How about having them report about their science lab work right on their very own website?
