Diigo has a helpful Chrome extension which allows users to bookmark, then add digital highlights and interactive sticky notes to webpages and articles. Annotated items can be shared with other Diigo users and groups.
It allows users to collaborate and share what they are reading and notes users attach. The material can be accessed online, anywhere, using most any device. Both public and private groups can be created which allows for specificity in sharing. Items can also be tagged making it easy to search and find materials relating to a certain topic.
The Diigo Chrome extension is an exceptional tool for the classroom! Reading and research materials can be bookmarked, highlighted, annotated, and notes added. Web resources can be shared with the whole class or used for differentiating with small groups and individuals. Check out this video for an overview of its features.
