INTRODUCTION

English translation pending.

CORE DEFINITION

Bronfenbrenner's ecological systems theory places the developing person inside nested systems: the microsystem of direct contact such as family and school, the mesosystem of connections between microsystems, the exosystem of indirect settings such as a parent's workplace, the macrosystem of culture and values, and the chronosystem of historical period and life stage. Development is the result of multilayer person-environment interaction.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Move out layer by layer: when a behavior appears, check each system from the innermost out. - Fix the connections too: change the links between settings, not only the settings themselves. - Include time: bring in the cultural background and the historical moment.

No single layer determines development; each layer constrains what the inner one can do, and the connections between settings carry more influence than any setting alone. Because the outer layers set the conditions the inner ones operate under, a factor at the level of policy or culture shows up as behavior at the level of the child.

First Principles

In philosophy and science, a first principle (or first principles) refers to a basic proposition that cannot be deduced from any other proposition or assumption. The concept originates in philosophy from Aristotle's doctrine of the 'first cause', while in Kantian philosophy, its corresponding form is called a 'postulate'. In mathematics and formal logic, first principles manifest as 'axioms' or 'postulates', constituting the absolute starting point of logical deduction. In physics and other scientific fields, if the research process is entirely based on fundamental physical laws, without relying on empirical models or parameter fitting, it is referred to as 'from first principles' or 'ab initio'.
