Document Summary

Focus on local problems (such as water level in a cup) Identity (conservation)- an object can change its appearance without changing its basic nature. Water looks different after it has been poured into another glass but the same water. Piaget believes in logic and the world just is how it is. Operation- internalized action that is reversible and part of an organized structure. Can be illustrated by explanations of conservation judgment- If you pour it back (reversibility per se) The water goes up higher, but the glass is thinner (compensation) You didn"t add any or take any away (addition, subtraction) Can reason about conservation in the abstract without concrete examples. Imagines all possible factors, tests them independently, keeps track of the results. E. g. discovering and stating the relation between angle that a billiard ball hits the table and angle of its rebound. Decreasing egocentrism (decentration) as the chile adapts better to reality.
