Our school would like to begin using Web 2.0 applications with our students. We are a K-5 school. Students involved this year would be 5th graders. One of my major cautions about Web 2.0 and elementary students is keeping them safe on interactive websites. I think I would begin by using a child-centered wiki that keeps a record of each change made. I do have a lab where the classroom teacher and I can carefully watch what each student is posting. I still have trepidation about who in cyberspace might see the postings. Each child would be given a handle and would not use his/her own name.
I would like see what your thoughts are on Web 2.0 and elementary school students.
