Final answer:
Pairing the student with a peer whose level of skill and concept mastery is slightly more advanced.
Step-by-step explanation:
The best strategy to support learning for a 13-year-old student, based on Lev Vygotsky's theory of the zone of proximal development, would be option C: Pairing the student with a peer whose level of skill and concept mastery is slightly more advanced.
This strategy aligns with Vygotsky's belief that learning is enhanced through social interactions and collaboration. By working with a peer who has a slightly higher skill level, the student can receive guidance and support to move beyond their current level of understanding.
For example, if the 13-year-old student is working on a math problem, their peer can offer assistance, explain concepts, and provide different strategies for solving the problem. This process promotes cognitive growth and allows the student to scaffold their learning to reach higher levels of understanding.
