Wordle and Tagxedo are just some of the fun, visually-appealing word collages that appear on my website. Aside from obviously making a website or classroom more fun, there are a variety of ways anyone could use this with their students, especially in English classes. These programs analyze word usage and make more frequently used words more prominent. When critically studying writing, analyzing what words were used and how often is imperative. Students could take a work (a passage from a novel, a poem whatever) and see how often an author used those words and the analyze why.
Students could also use it with their own work. If they wrote a poem they could put it in one of these programs and similarly analyze their word choice. They could also explain why they chose the shape they did (in Tagxedo) and how to applies/relates to their writing. These programs could enhance less interesting papers, poems or projects!
I could also use it with new vocab words. It would be easy to highlight which words are going to super important down to slightly important. It could help students focus their studies and know what words to cram last minutes. I could also use it as quick way to convey the main characters, setting, themes, motifs etc... of novels we are reading in class. Students could use this as a quick refresher, or they could make their own. Highlighting what aspects of the book they find the most important or interesting.
