Here is a Wordle of the comments from my first post, Engagement is Learning (hat tip to my course tutor for this idea!).
I'm using this in my Current Events programme. As a class we are looking at a particular news item that we want to explore in greater depth. After a general first reading we discuss what we think the main ideas and key concepts are, and then paste the story into Wordle and see what stands out. My students really love the visual aspect of it, and the fact that you can randomise or customise it to change its shape, colour etc.
I can also use this to add to my spelling and word study programme. They can select several relevant words from the article, and avoid selecting low-frequency words that are a bit obscure or chosen just because they looked difficult!
Another cool tool is one you'll find on this blog, called AnswerTips , which allows you to double-click on any word on the blog that isn't a link, and it provides a box with a definition, synonyms, etc. Great for the class blog!
