Using research findings, describe one criticism of Piaget's description of the shift to concrete operations.
What will be an ideal response?
The ideal answer should include:
1. Students may choose any of the following criticisms:
a) Research data have shown that the shift to concrete operations is gradual, rather than sudden and stagelike as Piaget claimed.
b) Researchers have found that when children are tested with familiar materials or less confusing questions, they understand the concepts tested for in Piaget's tasks earlier than Piaget thought.
c) Piaget claimed that concrete operations are universal across cultures, but research has shown that an understanding of concrete operations depends in part on familiarity with the materials.
