A word cloud is an image made up of words with prominence assigned to words that are used more regularly. For example an essay about Seamus Heaney which is pasted into a word cloud tool (like tagxedo or wordle) might give preference to the words Seamus and Heaney as they are likely to be most commonly used in the essay. Below are two examples of word clouds.
Word clouds are a great visual for the classroom. They can be used for any topic being taught and students can really get involved with making them. The can be printed out and put onto the classroom walls.
