Wordle is a toy for generating “word clouds” from text that you provide. The clouds give greater prominence to words that appear more frequently in the source text. You can tweak your clouds with different fonts, layouts, and color schemes. The images you create with Wordle are yours to use however you like. You can print them out, or save them to the Wordle gallery to share with your friends. Wordles can be used in TONS of ways in education. I am compiling a list of ideas where you can use wordle as a great aid in education, I will post it as soon as I am finished insha Allaah.
Here is a wordle I created from my Delicious bookmarks’ tags.
P.S: Instead of compiling a list, I found one with contributions from a large number of users. So check it out below
