Answer:
guided participation
Explanation:
The answer is
"guided participation".
A guided participation is a process by which a person who is less experience in a particular work or a task is guided and taught well by an expert or an experienced person and helps him to gain knowledge and become competent in the task. Here, people take part in activities and take guidance from the more experienced person and master that thing.
Thus Vygotsky would refer to this skill acquisition as being the result of "guided participation".
