Conclusion
Piaget conclude that his theory was correct.
4 of 7
Criticism 1
They way the children were questioned. The nature of the task. Not child friendly.
5 of 7
Criticism 2
It didn't have much meaning to young children. When a naughty toy was used to move the counters 60% of the children in pre-operational stage passed the conservation of number test. The test had been made child friendly and it contradicted Piagets'
6 of 7
Criticism 3
Small sample. Unable to generalize findings. Especially as part of Piagets' theory states that development is universal. How can he be sure?
