Final answer:
Peers play an important role in socialization for school-aged children, while the mass media influences beliefs and norms.
Step-by-step explanation:
Peers play an important role as agents of socialization for school-aged children. One example of the role peers play is when children learn social norms and behaviors by observing and imitating their friends. For instance, if a child's peers start using slang language, the child might also start using it to fit in.
As for mass media, it has a significant influence on socialization. One example could be a photo of a group of teenagers watching the news on television or reading a newspaper. This represents how mass media can shape their beliefs, reinforce societal norms, and provide information about current events.
