Inherent in all individual is an impulse to grow. Human growth has additional dimensions, that is, to develop a more adequate structure and the ability to function better. Piaget (1973) argued that children do not receive knowledge passively, but rather, discover and construct knowledge through activities. Malcom Knowles suggested that the educators as a result of accelerated social change must rethink their roles and concentrate on teaching students the skills and attitudes needed for self-directed inquiry (cited in Meyers, 1986).
