You will remember Piaget's image of the child as tireless rational scientist, trying to make sense of the world without recourse to context or other people. Those who argue objective and subject against this see the world in which children live as simultaneously objective and subjective, meaning that there are things to explore in the world and that each person's exploration will be unique. So the child will make knowledge his or her own and will do what is to be learned into what is already understood through cultural and collective knowledge. The implication of this is that children cannot come to make knowledge their own if they are required to integrate it into something of which they have no understanding.
