Social health means the same as social order, and is guaranteed when nearly everyone accepts the general moral values of their society. Hence structural functionalists believe the aim of key institutions, such as education, is to socialize children and teenagers. Socialization is the process by which the new generation learns the knowledge, attitudes and values that they will need as productive citizens. Education's primary role is to convey basic knowledge and skills to future generations. Although this aim is stated in the formal curriculum, it is mainly achieved through the hidden curriculum, a subtler, but nonetheless powerful, indoctrination of the norms and values of the wider society. Students learn these values because their behavior at school is regulated (Durkheim in ) until they gradually internalize and accept them.
