Some educators advocate confronting strong language directly every time it is used rather than paying little or no attention to children who curse on school grounds.
"It's not enough to tell a child that we don't use that type of language. It sends it underground," said Linda Lewis-White, an Eastern Michigan University professor who trains elementary school teachers.
