Which theorist is known for developing age-stage learning concepts?

The theorist known for developing age-stage learning concepts is Piaget. His work focused on the cognitive development of children and outlined a systematic theory of how children progress through four distinct stages of cognitive growth: the sensorimotor stage, the preoperational stage, the concrete operational stage, and the formal operational stage. Each of these stages corresponds to specific age ranges and reflects the ways children's thinking evolves as they mature.

Piaget's emphasis on the idea that children think differently than adults, and that their cognitive abilities develop in an orderly sequence, underscores his significant impact on education and child development. His framework helps educators understand the appropriate expectations for children’s learning based on their developmental stage, guiding them in creating suitable learning environments and experiences.

In contrast, other theorists have different focuses: Gardner is known for the theory of multiple intelligences, which emphasizes varied types of human intellectual capacity; Vygotsky is recognized for his social development theory, particularly the concepts of social interaction in learning and the zone of proximal development; whereas Erikson introduced a psychosocial development theory outlining eight stages of human development that focus on emotional and social aspects rather than strictly cognitive ones.
