This isn’t just "how to make some numbers and vector graphics look clever together." It’s a narrative language--it’s "representation plus interpretation to develop an idea," to quote Franchi.
What a great opportunity for math and art teachers to collaborate and provide students with engaging new ways of representing their ideas and analysis of information. I love the idea of this being a "narrative language" it's a wonderful example of "new literacies" and how we communicate visually in a digital world. Why are we still having students create powerpoints that take words or graphs from text or online and regurgitate them in a slide show...when they could be creating visual representations of their interpretation of an idea?
