Vicki Davis recently wrote an article for The Atlantic about her decision to leave the business world to become a teacher. Those of you who, like Vicki and myself, worked in other fields before teaching will probably relate to Vicki’s story.

On the same page as Vicki’s story is an interesting infographic about the mathematical influence of one school principal on a community. The infographic has some interactive elements that will allow you to see how that one person’s influence projects over one year, five years, and ten years. I can’t say that I agree with everything in the infographic and The Atlantic doesn’t disclose the source of their statistics, but it’s still interesting. I would like to see the same type of infographic showing the influence of one teacher over five, ten, or more years.
