Ecological systems

A child is nested: family, class, parents' work, culture, and time. Teaching the child without seeing the nest is guessing.

Why it matters when you teach

Sleep, bus ride, food, a parent working nights, a classroom of 28, a culture that values quiet — these are not background. They are the developing system. When a strategy fails, zoom out one layer.

Core ideas

Microsystem

Face-to-face: home, class, team.

Mesosystem

How those worlds talk to each other. A teacher who knows the parent changes the child.

Exo / macro / chrono

Parents' jobs, policy, culture, and historical time — including screens as a new weather.

In the room

  • Ask what morning looked like before you interpret 'attitude.'
  • One warm parent-teacher loop is an intervention.
  • Do not run a European quiet-classroom script on a culture that learns out loud without translating.
  • When a child changes, ask what else changed: move, new baby, new shift at work.

Try this

  • Map a child's week on a napkin: sleep, food, movement, people. Teach the gaps.

Hold it lightly

  • The model is vast and hard to measure. Use it as a diagnostic zoom, not a checklist of 40 variables.
