Diigo can provide a way to enrich or extend learning about a topic. Through formal or informal activities, students can research websites about a class topic and post their findings to Diigo lists or groups. Students can also create relevant annotations for others to see.
Teachers could use Diigo in this manner in a number of ways.
Classes could begin a topic of study with an information search to preview the content.
Classes could supplement their textbook with information from the web. Diigo could facilitate student discussions about the bookmarks. Annotations could be used to gauge student thinking.
Classes could use Diigo to review content in a type of fact-checking activity. The internet could be used to research important points of study and see if that information can be confirmed with bookmarks.
