Which theorist proposed the stages of cognitive development and influenced instruction to be developmentally appropriate with concrete experiences for younger learners and opportunities for abstract reasoning for older learners?

• A. Vygotsky
• B. Piaget
• C. Erikson
• D. Skinner

Answer: (B)

Think about how children's thinking changes in quality as they grow. Piaget argued that learning should match a child’s current way of thinking, because cognition unfolds through distinct stages: sensorimotor, preoperational, concrete operational, and formal operational. This means instruction for younger learners should rely on concrete, hands-on experiences and tangible objects to build solid mental representations. As children move into the concrete operational stage, they can handle more complex reasoning with real-world materials and patterns. For older learners approaching or in the formal operational stage, education can introduce abstract concepts, hypothetical scenarios, and deductive reasoning. This stage-based view directly informs developmentally appropriate practice by aligning tasks with the learner’s current cognitive capabilities and gradually guiding them toward more abstract thinking. While other theorists emphasize different aspects—such as social scaffolding in Vygotsky, psychosocial tasks in Erikson, or behavior shaping in Skinner—the emphasis on stage-appropriate cognitive development and the progression from concrete experiences to abstract reasoning is a hallmark of Piaget’s influence.
