How I Use It
I have tried it for summarizing thoughts from students on a character ed. topic. Words mentioned during discussion went into Wordle to show what seemed to be most important to the people in the class.
I've also seen it used to assess needs. Participants enter the areas they want to learn more about and the teacher wordles it to see the trends.
Wordle is so nice for creating a visual idea of quantity. Those who learn visually are helped by this technique. It's easy to use and quick also.
