This is about more than just taking choir in high school - it is a fundamental problem in our educational system examined here by a high school senior. Only 12 minutes long. When my sons were in HS (they graduated in the mid 1990's), I remember their discussions of just exactly this problem. He offers some solutions, but no quick fixes.
What Eric Whitacre has achieved here is simply awesome. Think of how teachers could harness the power of the social web for collaboration and learning using his genius as inspiration and example!
