According to the NYT,
Visualizations of New York Times articles can help highlight key vocabulary, content and concepts. For instance, students could create a Wordle using three articles on the recession to try to identify key terms they should learn more about.
Examining word clouds can not only provide new vantage points for literary and language scholars, but also help English-language learners, and others who have trouble with complex texts, to see patterns.
Students can play with the font and colors and make as well as save and reuse “Wordles” of their own, so the possibilities are endless. They can use their own writing to see what words they overuse, perhaps.
