Research  Teaching students to research is a common standard across all grade levels, elementary, middle school, high school, and beyond. Diigo excels as a research tool: Students can save relevant websites to lists in their Diigo student accounts. Each saved bookmark captures the URL and a screenshot, and can be searched later. Students can highlight important information right on the website, using Diigo. Later, when students return to the website, they find the reason they saved the bookmark in the first place. Students can use virtual sticky notes to summarize the important points of information from the website. This activity will mimic the time-tested procedure of using note cards to summarize and organize research projects. Students working on similar topics can create and join groups in order to collaborate. Later, when students need to document their sources, Diigo can be used to recall website URLs for citing sources.
