I used wallwisher with my class last year and found it really good for brainstorming lots of ideas simultaneously. This year, I have a class that have a lot of ideas and are quite vocal about them. Using wallwisher meant that they didn't have to wait their turn while I wrote or typed up their ideas. The source of motivation was using the book 'The Lorax' by Dr Seuss. We have been looking closely at sustainability and what it means. Here is what they came up with.
