Whew. Worked on this for a long time. There is so much that is involved in Infographics! If you haven't checked out the professional development for Infographics, do it - it is really great: http://edex.adobe.com/professional-development/workshop/creating-infographics/
So this is a unit that I designed to introduce students to infographics, the different styles, how to choose the right visual vehicle, and ultimately the task of developing an infographic on the world population of stray dogs. Included in the .zip file is: A 6-page student information packet with steps, tips, diagram, rubric, etc. And a 3-page unit-planning guide. Both are in interactive .pdf format with lots of hyperlinks, and also in InDesign .idml format so that you can revise and customize to fit your needs.
Please - I need your feedback. A project plan is never finished - with your help I will revise it and add to it to create something that will really inspire and invigorate students!
Also, I have a self-guided Infographics tour on my class website - check it out and tell me what you think: http://www.learndurkin.com/infographics.html
