Final answer:
Parents should follow a teaching strategy known as accommodation, according to Piaget's theory of cognitive development.
Step-by-step explanation:
According to Piaget's theory of cognitive development, parents should follow a teaching strategy known as accommodation. Accommodation is the process through which children change their existing mental schemes to incorporate new information or experiences that are different from what they already know. It is the opposite of assimilation, which involves fitting new information into existing mental schemes. By accommodating new information, children can expand and refine their understanding of the world.
