“All *places* are distant from heaven alike.”

—Robert Burton (1577–1640)

“It makes little sense to spend a month teaching *decimal* fractions to fourth-grade pupils when they can be taught in a week, and better understood and retained, by sixth-grade students. Child-centeredness does not mean lack of rigor or standards; it does mean finding the best match between curricula and children’s developing interests and abilities.”

—David Elkind (20th century)
