Most teachers in the field of early childhood education pour a great deal of thought, energy, and enthusiasm into what they do. If asked why they invest so much in their profession, they're likely to list a number of reasons: they love children and enjoy being around them; they sincerely care about their welfare; and they feel a sense of pride and accomplishment in helping children grow and develop. According to a social development theory proposed by Erik Erikson (1950, 1959), teachers may also be motivated by something called "generativity"--that is, a concern for the next generation. While they certainly enjoy the "now" of being with children, they also realize that their work can help them enjoy a happier and more successful life in the future. They probably realize, as well, that what they do can make the world a better place for future generations.
