I am thinking of using KidBlog, because I want my students to be able to have a space to showcase their work, projects, and accomplishments. I would also want them to be able to review and respond to the work they have done, as in a reflection upon their steps in achieving goals and how they felt about their work. This site would allow parents to view the work of the student periodically and have a good sense of how their child feels about themselves as learners. It is also seems to be a site where I could moderate and have a record of student growth throughout the year.
Students can post stories, videos, examples of work, interviews, etc. The possibilities seem endless.
