With reference to Jean Piaget's theory of cognitive development, consider the following statements:
- 1. According to Piaget, children are active knowledge builders and little scientists who construct their own theories about the world.
- 2. During the 'Pre-operational Stage' (2 to 7 years), the quality of 'conservation' is fully developed in children, enabling them to understand that changing the shape of an object does not change its quantity or mass.
- 3. In the 'Concrete Operational Stage' (7 to 11 years), children begin to think logically, but their thinking is limited only to concrete or direct objects and events.
- 4. In the Formal Operational Stage, adolescents develop full capacities for deductive reasoning and abstract thinking.
Which of the above statements are correct?
Detailed Explanation
The analysis of the statements given in this question is as follows:
Statement 1 is correct: According to Jean Piaget, children are little scientists who construct knowledge by active interaction with their environment.
Statement 2 is incorrect: The quality of 'conservation' does not develop in the pre-operational stage but during the 'concrete operational stage' (7-11 years). Children in the pre-operational stage lack conservation.
Statement 3 is correct: In the concrete operational stage, children begin to understand conservation, classification, and reversibility, but their thinking remains limited to concrete objects rather than abstract ideas.
Statement 4 is correct: In the formal operational stage (above 11 years), abstract thinking, hypothetico-deductive reasoning, and scientific thinking develop.
