Final answer:
Ben teaching Hannah to tie her shoelaces is an example of informal education, a form of learning by doing wherein knowledge is acquired outside of a formal educational setting, often through observational learning and cognitive development.
Step-by-step explanation:
The concept illustrated by ten-year-old Ben helping his 5-year-old sister Hannah learn how to tie her shoelaces is informal education.
Informal education occurs when skills or knowledge are passed on without a structured curriculum, often through everyday experiences and interactions within a community or family setting.
In this scenario, the older sibling is sharing a life skill with the younger sibling, which is a common form of learning by doing and an example of how children often learn from each other.
Children also learn through observational learning, where they observe the behaviors of others and imitate them. In a broader sense, this example also touches upon the cognitive development of children, as older children often carry the responsibility of teaching younger ones, applying their understanding of how others think and learn.
