Final answer:
The nested system that includes family and preschool is the Mesosystem.
Step-by-step explanation:
The nested system that includes family and preschool is the Mesosystem.
In Bronfenbrenner's ecological systems theory, the mesosystem represents the connections and interactions between different Microsystems, such as family, school, and peers. The mesosystem is where the influences from different contexts come together and impact a child's development.
For example, a child's experience in the family setting can be influenced by the interactions between the family and the preschool they attend, such as communication between parents and teachers, coordination of activities, and shared values.
