Functional structuralism is a way of looking at things that focuses on understanding how different parts of something work together as a whole. It looks at how different pieces of a system interact and how the relationships between them shape the system as a whole. For example, it can be used to understand how the different parts of a family work together to make the family function. It looks at how things like roles, rules, and communication affect the way the family functions. It also looks at how different parts of the family interact with each other and how that affects how the family as a whole works.
