Which theorist claimed that the environment affects the development of a child?

Bronfenbrenner's ecological systems theory emphasizes that a child's development is significantly influenced by their interactions within various environmental contexts. He proposed that development occurs within a series of nested systems, including the microsystem (immediate environment such as family and school), mesosystem (interactions between different parts of the microsystem), exosystem (external environmental settings that indirectly influence development), and macrosystem (wider cultural and societal factors). This comprehensive framework illustrates how different layers of a child's environment interact and contribute to their overall development, highlighting the importance of both direct and indirect influences from the surroundings. Understanding Bronfenbrenner's perspective underscores the idea that a child's experiences in different environments shape their growth and learning, which is crucial for educators and caregivers in fostering supportive and enriching environments for children.
