Magazine editorial: School days

A national magazine, specialized in in-depth analysis, requires an image for an article on education. They need a suitable image. The working title is "School Days." We're not sure what angle the article takes but the magazine rarely publishes "feel good" stories. Submit a photo of something school-related that can serve multiple purposes. This might include a child's hand gripping a pencil, a row of school lockers, teens with their heads buried in books, etc. What the definitely don't want are images of kids smiling into the camera.
