Which concept is part of Vygotsky’s theory?

An MKO is someone who has more knowledge than the child, allowing them to guide the child throughout learning. Whenever the child is having difficulty, they can ask the MKO for help. Furthemore, an MKO could even be a child’s friend and the child may gain more knowledge through discussing topics together. Many teachers use this technique to aid children’s learning. In the classroom, a child who is having difficulty with a topic could be made to sit next to a child who has more knowledge in the topic. This may cause a discussion of the topic which could lead to the child having a better understanding of the topic that they were struggling with.
