In March 2013 Edubloggers will be hosting a student blog challenge.
Each week students will be given a specific challenge to do on their blog. Challenges are designed to help improve commenting and posting skills, learn how to use all the elements of a blog, and interact with classrooms all over the world. We will be participating in some of the challenges on our class blog, and I invite students to take up the challenges on their own blogs as well. (Everyone will have their own blogs by March.)
For more information, or to sign up please visit this site or the blog roll on the sidebar. Good luck, and good blogging!
