Bronfenbrenner's Ecological Systems Theory

Jul 23, 2025

Overview

This lecture introduces Bronfenbrenner's Ecological Systems Theory, explaining how a child's development is shaped by multiple layers of environmental influence rather than biology alone.

Bronfenbrenner’s Ecological Systems Theory

  • Bronfenbrenner argued that environment, not just biology, shapes children's outcomes.
  • The theory identifies five ecological systems influencing a child: Microsystem, Mesosystem, Exosystem, Macrosystem, and Chronosystem.
  • Poor environments often lead to negative family and school experiences, making success harder for disadvantaged children.

The Five Ecological Systems

  • Microsystem: Direct influences (family, friends, school) surrounding the child daily.
  • Mesosystem: Connections between microsystems (e.g., parent-teacher relationships).
  • Exosystem: Social settings that indirectly affect the child (e.g., parent’s workplace).
  • Macrosystem: Broader cultural, social, and economic factors (e.g., ethnicity, societal norms).
  • Chronosystem: Changes over time affecting the child and their environment (e.g., divorce, parental remarriage).

Impact and Extensions

  • Bronfenbrenner influenced the creation of the Head Start program to support disadvantaged children.
  • Later, the bioecological model included gene–environment interactions, emphasizing environmental influence on genetic potential.
  • Parent-child relationships are deeply embedded in broader social structures.

Key Terms & Definitions

  • Microsystem — Immediate environment directly impacting the child (family, school, peers).
  • Mesosystem — Interactions between elements of the microsystem.
  • Exosystem — Indirect influences from social structures the child doesn’t interact with directly.
  • Macrosystem — Overarching societal and cultural influences on all lower systems.
  • Chronosystem — The dimension of time, reflecting life changes and transitions.

Action Items / Next Steps

  • Draw five concentric circles with yourself in the center and a timeline below; fill in all influencing people, institutions, and forces from your life.
  • Add significant past and future events to the timeline.
  • Consider how each system shapes your experiences.
