Citelighter, one of the most useful extensions I have seen in a while is one I cannot wait to see working in a classroom with Chromebooks! This extension, or add-on to the Chrome Browser, allows students to highlight information as they research on the web, annotate and remark about the information and then send the information to a Google Doc or Microsoft Word. As students gather information Citelighter actually creates a bibliography for the students in the style of the students' choice. This awesome resource is free!
Check out the video about Citelighter for a really good idea of what this can do for you and your students ad they research.
