Bronfenbrenner's Ecological Model

Aug 26, 2025

Overview

This lecture explains Bronfenbrenner's ecological systems theory, outlining five environmental layers that impact human development and how their interactions shape individual growth.

Bronfenbrenner’s Ecological Systems Theory

  • The theory provides a framework for understanding how layered environmental factors influence human development.
  • Development is shaped by five interconnected systems, ranging from immediate relationships to broader societal contexts.

The Five Systems

  • Microsystem: Immediate environments such as family, school, and friendships directly shape behavior and emotions.
  • Mesosystem: Involves connections between microsystems; parent-teacher collaboration can enhance a child’s academic and social development.
  • Exosystem: Indirect environments (e.g., parents’ workplace) affect the individual; parental job stress can impact a child's well-being.
  • Macrosystem: Broad societal influences, including culture, laws, and values, affect how children are raised and educated.
  • Chronosystem: The dimension of time, including life events and historical changes (e.g., economic recession, moving countries), influences development.

Implications and Applications

  • Social changes like technology advancement affect multiple system layers, altering development experiences.
  • Educators and parents can enhance development by fostering positive interactions within and between systems.
  • Schools collaborating with families and communities can better support student growth.
  • The theory contrasts with stage-based theories (e.g., Piaget, Erikson) by highlighting the influence of multiple interacting environments.

Strengths and Criticisms

  • Provides a comprehensive view of developmental influences but may be seen as too broad and complex for specific situations.
  • Critics note it may not account for individual differences in environmental experiences.
  • Refinements to the theory now emphasize the importance of time and historical context.

Assessment Tools

  • Ecological models guide assessments of family, school, and community to support developmental needs.

Key Terms & Definitions

  • Microsystem — Immediate surroundings with direct interactions (family, school, peers).
  • Mesosystem — Connections between microsystems (e.g., parent-teacher relationships).
  • Exosystem — Indirect external environments affecting the individual (e.g., parent's workplace).
  • Macrosystem — Cultural, economic, and societal influences shaping development.
  • Chronosystem — Time-related changes, including life events and historical shifts.

Action Items / Next Steps

  • Review examples of each system and consider how they interact in real-life situations.
  • Prepare for discussion: Compare Bronfenbrenner's model with stage-based development theories.
