Paigets 4 stages of cognitive development.

Can you please some primary research. What I mean by primary research is that you will use one of the descriptive methods. To actually test the predictions from the theory When you apply Piaget's theory, We will be using his clinical interview techniques to more directly examine the thinking of a child--For example- present the child with several examples of conservation problems and describe how he or she responded. Also use an observational method to describe, for example, "transductive" reasoning. Note that if you do use a naturalistic observation for Piaget you need to clearly connect the behavior with his stage-related schemes. I do suggest you to combine the two techniques if using Piaget's theory.
