What are Bronfenbrenner ecological systems theory?

Bronfenbrenner's ecological systems theory is a framework that explains development as the result of interactions between individuals and their environments. It consists of multiple systems such as the microsystem (immediate environment), mesosystem (connections between microsystems), exosystem (external environments), macrosystem (cultural values), and chronosystem (historical context). This theory emphasizes the importance of considering multiple levels of influence on an individual's development.
