Answer:
Scaffolding.
Explanation:
As Carmen's skill improves, her father steps back, letting her try on her own. This example illustrates the concept of scaffolding. Providing​ clues, and encouragement to help children accomplish a new task is known as scaffolding. A scaffold supports the workers while the building is fixed. It is a way of supporting Carmen when she was learning to fit pieces into a wooden puzzle form. The scaffold is needed up to the time when the way to fit the pieces on her own is acquired.
