Explanation: Piagetian refers to any relation to Jean Piaget (1896–1980), Swiss developmental psychologist and philosopher known for his epistemological studies with children. Jean Piaget placed great importance in the education of children.

He described 4 stages of development each with a few subtopics. They are

1) The sensorimotor stage

2) preoperational stage

3) concrete operational stage
