The correct answer is True
According to Vygotsky, the student's cognitive development occurs through social interaction, that is, through his interaction with other individuals and with the environment. For substantiality, at least two people must be actively involved in exchanging experience and ideas.
The interaction between individuals enables the generation of new experiences and knowledge.
Learning is a social experience, mediated by the use of instruments and signs, according to the concepts used by the author himself.
A sign, in this way, would be something that would mean something to the individual, such as spoken language and writing.
Learning is a social experience, which is mediated by the interaction between language and action.
For learning to occur, social interaction must take place within the zone of proximal development (ZDP), which would be the distance between what the subject already knows, his real knowledge, and what the subject has the potential to learn, his potential knowledge .
Thus, learning occurs in the interval of the ZDP, where real knowledge is that which the subject is able to apply alone, and the potential is that which he needs the help of others to apply.
