This word cloud was created using wordle.net. A word cloud bases the size of a word on the frequency it appears within a source document. In this sample, I have created a word cloud for the Declaration of Independence. Larger words appear more often in the text.
Any text can be copied and pasted into Wordle. This visual analysis of a document can be a great help for students to see themes in what they are reading. This could also be used with student-created text to look for theme and word choice.
