The importance of empathy as a character trait is garnering increased attention in an age of rapid technological change. In Denmark, empathy has long been a part of the zeitgeist of the nation, taught and valued everywhere, from preschools to corporate suites. By many measures, Denmark ... excels at instilling emotional well-being. Still, Denmark is facing challenges that would sound familiar to American educators. At the Hedegrdenes school ... one-third of the 400 students, from the first year of school through the ninth year, come from immigrant backgrounds, and another third from what administrators call troubled homes. As a result, says Thomas Brinch, vice principal, the work with empathy is more important than ever. The kids need to treat each other with respect no matter where they are from, what their religion is." Schools see empathy as a way to deal with another challenge as well: the saturation of social media. In the classroom of Ida Nielsen, a fifth-year teacher at the Hedegrdenes school ... the class has drawn up social media user guidelines together and is now discussing what they mean in practice. One of the first rules sounds simple enough: Don't say anything mean. But it leads one boy to question if that just applies to people, or whether they may make negative statements about not liking longer school hours. Such discussions are crucial, says Ms. Nielsen, when asked about the pressures to devote time to academic learning during the day. "This is their lives," she says.
