Case of study

 Piaget considered the concrete operational stage is a major turning point in the child's cognitive development, because it marks the beginning of logical or operational thought. The child is now mature enough to use logical thought or operations (i.e. rules) but can only apply logic to physical objects (hence concreteoperational). Children in this stage are from 7 to 11 years old.

My case of study is to show if Piaget's theory is true in a child of our coountry. I chose one of my nephews: Abraham Ismael Calderon Martinez, he is 10 years old. He is in fourth grade at Complejo Educativo Jorge Larde. He lives with mom, dad and brother.

I did three short experiments to demonstrate if he had gain the ability of conservation. Th ability of conservation is the understanding that something remains the same eventhough it changes in appearance.

The first experiment consisted on showing him two glasses of the same shape and colors and the same quantity of  water. I asked him which of them had more water or if he thought they had the same quantity of water. He answer, without doubting that they had the same quantity of water. Then, I poured the water of one glass to a different one so that it seems it had less water. I asked him the same question and he answer that the new glass had less water but thought it for a while and answer: It is the same quantity but is because of the glass that looks defferent.

The second one, was to put a certain number of cubes in two rows. I decide to put five and five. I asked him if one of them had more cubes or the same. He answered that both had 5 cubes. Then, I changed the position of one cube´s row so that it seems it had more because it was longer. I asked him if it still had the same number of cubes. He thought for a moment and answer that yes it had the same number of cubes that I had just spread them out.

 The third experiment was to see if he could conserve the lengh. So, I put two rows of the same lengh and asked him which was longer. He answer both are the same lengh. After that, I move one row a little to the right and asked the same. He answer that the one I did not move was longer but he retracted and he said they were still the same lengh but they were moved.

This experiments show that Piaget´s theory is true. That children this age use logical thoughts. In the way Abraham answered showed me that he is able to analyse things logically and give a logical explenations for the things he can see or in other words physical objects.
