Bronfenbrenner's Theory, also known as the Ecological Systems Theory, explains how different environments influence human development. It consists of five layers: the microsystem, which includes immediate surroundings like family and school; the mesosystem, which connects different microsystems; the exosystem, which involves external settings that indirectly affect the individual; the macrosystem, which encompasses cultural and societal influences; and the chronosystem, which considers the dimension of time and changes over the lifespan. This theory emphasizes that development is not just influenced by individual factors but also by the complex interactions between various systems. By understanding these layers, researchers and educators can better support individuals in their growth and development, recognizing the importance of context in shaping experiences and outcomes.
