Roots of empathy--an evidence-based program developed in 1996 by longtime educator and social entrepreneur Mary Gordon--has already reached more than 270,000 children in Canada, the U.S., Japan, Australia, New Zealand, and elsewhere. Now, as the New York Times reports that empathy lessons are spreading everywhere amid concerns over the pressure on students from high-stakes tests and a race to college that starts in kindergarten, Mary Gordon explains the value of and how best to nurture empathy and social and emotional literacy in all children--and thereby reduce aggression, antisocial behavior, and bullying.
