Great question Deanna. Consider this...A Symbaloo webmix can be designed by the learner so that all of their learning tools are at there fingertips. As students design their learning path, it might be helpful for them to create a "digital" personalized learning environment. This PLE would allow them quickly access all of the content, resources, and tools on their learning path.
Are there other ways to do this? Yes. A student could create a folder in their bookmarks and store it all there. Could a student use Diigo (a social bookmarking and annotating tool)? Absolutely. What about a Pinterest board? Yep. For this course, we chose Symbaloo, but don't feel limited or obligated to use it. If you have a different tool feel free to use it. My only caveat is that you share it with the group.
