The key ideas and concepts in Vygotsky’s theory of cognitive development include the zone of proximal development, which entails the difference between the child’s abilities to perform and excel in tasks when acting alone and when getting assistance from a more knowledgeable person. The other key concept includes scaffolding, which is a type of teaching in children through which the teacher assists on a required basis and then only as much as the child needs to complete a certain task independently as much as possible. An example of scaffolding includes helping children who experience difficulties in task performance so that they can complete an assignment on time and have a better understanding.

Piaget’s theory of learning has various similarities to that of Vygotsky in that both are constructivist theorists. They both have the perception that children are active learners who actively organize preexisting information along with new one, postulating that knowledge is constructed through each subject and not as a result of the acquisition of answers. Another similarity is that both think that cognitive development decreases and that it begins with conflict. For example, the realization that an idea does not fit with prior knowledge but requires new response to allow for balance, thus initiating conflict and decreasing previous information.

The difference between Piaget and Vygotsky’s theories of learning is based on knowledge construction. In Piaget’s theory, learning occurs individually, and it is the conflict between the new idea and existing information that provokes the child to seek balance. In Vygotsky’s theory, learning occurs as a result of assistance from a more knowledgeable person, a teacher. Another difference between the two theorists is based on the stages of development. Piaget’s theory deals with cognitive development by universal stages while on the other hand, Vygotsky’s theory has no room for such stages in that the construction of knowledge through social interaction requires a different culture, making it difficult to generalize. Thus, Piaget’s theory depends on the stage of the subject, while Vygotsky’s theory depends on the quality of interaction of the assistant.
