The Boston Globe Magazine cited the work of professors Roger and David W. Johnson, leaders of the Cooperative Learning Center, in an article titled “What happened to losing?” Teaching children about healthy competition is the challenge presented by parent/writer Neil Swidey in the article, which notes that the Johnsons’ research has shown that “people working cooperatively, in the classroom or on the playing field, reach a higher level of achievement than people pitted against one another or working alone.” Swidey quotes David W. Johnson extensively in the article.
