Washington Post: In his Class Struggle blog, Washington Post education correspondent Jay Matthews writes about Ed Linz, a physics teacher at West Springfield High School in Fairfax County, Virginia. Linz believes that his students should have the experience of writing a substantial research paper. Not wanting to grade all those essays himself, he has devised an innovative solution: Require all his students to enter the DuPont Challenge Science Essay Competition. Matthews writes
[Linz] likes the essay contest much better than the science fair. To him, competing experiments mean stacks of liability forms and debates about outside help. “I got tired of judging parents’ work,” Linz said.
