Herein, what is the ecological systems approach? American psychologist, Urie Bronfenbrenner, formulated the Ecological Systems Theory to explain how the inherent qualities of children and their environments interact to influence how they grow and develop. Bronfenbrenner’s ecological model organizes contexts of development into five levels of external influence.What is Bronfenbrenner?Bronfenbrenner’s bioecological model is a theory of educational psychology that studies human development over time. Urie Bronfenbrenner was a Russian-American developmental psychologist whose bioecological model was integral to the formation of American Headstart pre-kindergarten programs.
