This question is about the enormous amount of debt accumulated by college students in the United States. The total amount of debt recently passed $1 trillion; what is the average amount of debt per student?
In October, I will be running a workshop through Math for America titled “Professional Development Through Social Media”. The goal of this two-hour workshop is to provide an overview of the opportunities for professional growth, collaboration, and reflection that teachers can find on various social networks.
As part of the workshop, participants will be invited to peruse interactions–posts, comments, exchanges, conversations–that highlight the nature and strengths of the various digital professional communities. I have a number of good starting points in mind, but I’d love to have more.
I invite you to leave a suggestion in the comments. Provide a link to something great and give a brief description of what this highlights about the online professional world. The workshop will include both math and science teachers, so links to non-math resources are definitely welcome. And please feel free to suggest your own work!
Thanks in advance for your help. Assuming this is successful, this post itself will become an example of the value of being connected!
This is another amazing anamophosis from Francisco De Comite, In “Hidden Pentagram”, the curved arms of increasing thickness form the image of a pentagram on the mirrored surface of a sphere. You can find out more about the artist’s work here.
This is another piece from the 2013 Bridges Mathematical Art Gallery.
The Museum of Mathematics has posted my Rosenthal Prize lesson, Sphere Dressing, on their website and made it freely available for download.
In this lesson, students explore the connections between plane and solid geometry by designing and building hats to cover a sphere. This set of activities, which includes options for grades 4 to 12, was part of my application portfolio for the 2012 Rosenthal Prize for Innovation in Teaching Mathematics , and I was honored to be named runner-up. A nice profile of the two winners appears in Scientific American here.
You can download my lesson, Sphere Dressing, here. You can find out more information about the Rosenthal Prize, and find more award-winning lessons for download here.

This question relates to the expansion of aptitude tests like the SAT and ACT. How much is spent each year on these two exams?
