One problem I find discouraging is that many websites that have super cool activities on them require an email address in order to use them. I have some very tech-savvy 5th graders who would enjoy places like animoto.com but the email address thing stops me.
Next year I’d love to try to have every 5th grader come to school with an email address already in place, or permission so that I can get them one, in order to have more freedom. Of course, along with freedom comes responsibility and appropriateness. I wouldn’t mind teaching either of those things if we could just have access to more areas on the web!
