Which educational practice is emphasized by Vygotsky in relation to children's learning?

Vygotsky's theory emphasizes the importance of social interaction in the learning process. He believed that children learn best when they engage with others, particularly when they can interact with peers or adults who are slightly more knowledgeable than themselves. This is closely tied to his concept of the "Zone of Proximal Development," which highlights the potential for learning that can occur with guidance.

Mixed-age groups foster a rich environment for learning where younger children can learn from older peers and vice versa. This allows for the sharing of different perspectives and skills, enhancing cognitive development through collaborative experiences. Social interactions in these settings provide opportunities for children to discuss ideas, negotiate roles, and receive feedback, all of which are critical to deeper understanding and application of concepts.

This practice aligns with Vygotsky's belief that learning is inherently a social process, making option B the most aligned with his educational philosophy. In contrast, the other options suggest isolated learning practices that don’t engage social interaction, which goes against Vygotsky's core principles.
