Ed Tech Ideas: I teach 3 different grade levels, and my different classes are always researching for one project or another. Students are always finding great sites, but at best, they bookmark it to their local computer, never to be seen by others. Now with our Diigo groups (I created one for each grade level), kids learn how to tag, organize, and share their finds with everyone else in the group. Everyone benefits from group knowledge, and the students learn an important skill that will stay with them and grow throughout their academic lives.
