"A new tool that can be added to this section is called VocabGrabber: Thinkmap Visual Thesaurus. Text from any source can be paste and copied and analyzed for key vocab words and concepts. It displays these in a tag cloud and the word list can be sorted in four ways: Relevance, A-Z, Occurrences, and Familiarity. Another great feature is that classifies the words according to subject/discipline. On the right hand side of the site, there are definitions and examples of the word used contextually. Copying and pasting can be eliminated if VocabGrabber is added to the toolbar. I will add this tool to the history students' blog and to mine. What a great way to improve comprehension."
