Using http://bubbl.us/ enables us to create concept maps. This is great for doing schemas. This could be used in the classroom as tools for words, synonyms and things alike, or students can make their own concept maps for brainstorming and ideas. By using concept maps we can see how students think differently.
Get students to create a concept map, and compare them to eachother. It's amazing the way other people think, especially young people! This could also help with profiling students and recognising their interests, strengths and needs.
