Piaget and Vygotsky were two psycologists who studied (among other subjects) the childhood and the cognitive development. The two scientists talked about the way a child can reach the learning, however they had different ideas about the help that the child receives and whether the s/he can learn by her/his own.
The main difference between both is that Piaget neglects the social, and Vygotsky focuses on it. Though both think that the child is an active learner, for Piaget, he’s alone in a world of objects and he learns by his own, passing through a series of stages, and for Vygotsky, the child is in a world full of other people, who help him to reach his ZPD.
Both, Piaget and Vygotsky, think that learning happens when action takes place. The difference is that, in Piaget’s opinion, action is a process that occurs in the child’s mind, whereas Vygotsky thinks that the action takes place outside, in the relationship the child has with the world.
But, what implications have these ideas and these two people in Language Teaching?
