Which contribution is associated with Piaget?

• A. Constructivism
• B. Classical conditioning
• C. Sociocultural theory
• D. Information processing model

Answer: (A)

Constructivism is Piaget’s key contribution. He proposed that learners actively build their own understanding by interacting with the world, rather than simply absorbing information from others. Cognitive development unfolds as children modify their internal mental structures, or schemas, through two main processes: assimilation, where new experiences fit into existing schemas, and accommodation, where schemas are altered to incorporate new information. This ongoing adjustment, driven by the need for balance, is called equilibration and explains how thinking becomes more sophisticated over time. Piaget also described distinct stages of development—sensorimotor, preoperational, concrete operational, and formal operational—each with characteristic ways of thinking and approaching problems. In practice, this means learning is most effective when students can explore, experiment, and confront their current understandings, with guidance that matches their developmental level rather than relying solely on repetition or direct instruction.

Classical conditioning belongs to the realm of behaviorism, focusing on learned associations rather than how thoughts evolve. The sociocultural theory comes from Vygotsky and emphasizes social interaction and cultural tools in learning. The information processing model analyzes how people encode, store, and retrieve information, focusing on cognitive processes rather than the construction of knowledge through interaction with the environment.
