Piaget’s stages of cognitive development, in my opinion, are like that of much of psychology: the theory is relatively logical, and might be accurate for some percentage of children in the world, but the conclusions drawn by Piaget are simply too specific and limiting to be applied realistically.  In general, the Sensorimotor stage is the basic shape of newborn-2 year olds’ development. It mentions several phenomena that are common in this age- object permanence, assimilation & accommodation,  etc. But the argument must be made that Piaget’s experiment’s parameters were insufficient, to say the least. His principles cannot be applied completely in real life.

It is difficult to implement psychology theories. It is always possible to find a ‘flaw’ in a psychological study or experiment, depending on how you think. In terms of education, there are too many factors that go into a child’s development, it is impossible to use only one or two techniques in a classroom. There are often cases of children who can be considered as ahead of their age’s ‘stage’ and need to be nurtured appropriately to ensure the rest of their development in school. The same goes for children who find themselves ‘behind’ where they’re theoretically supposed to be for their age. They need to be cared for and supported for the exact same reasons, but they need different help. Being a teacher is figuring out how to support their students so that they can learn, develop, and thrive.
