Afra Mohamed Taha Child Development Assignment No. 1 Piaget used a geometrical experiment called "cows on a farm" to test for conservation of area. To illustrate this, Piaget used green cardboard to represent farmland. Two identical green farms were established, each had a little wooden cow placed upon it, and subjects were asked whether the cows had the same amount of grass to feed upon. Piaget would proceed to equally add little cubic farmhouses to the models. In one farmyard the houses where all arranged in a tidy row, on the other farmland the houses were all scattered about. Until the ages of 8-9, children are irresistibly inclined to think there's less grazing land on the farmland which contains the scattered houses. 2007-09-08 http://facultyweb.cortland.edu/andersmd/PIAGET/a3.HTML Stage: First child; Preoperational stage (2-7) Second child; Concrete operational stage (7-11) Operation: Conservation of area Goal: The goal of this experiment is to examine the sense of conservation for the two children. Materials: Two green cardboard with the same size to represent the farms. Two little wooden cows. 12 cubic frame houses Procedure: - I placed the two green cardboards on a table. - I put one wooden cow on each of them. - I scattered 6 of the houses on one cardboard, to represent Farm 1 - I put the other 6 houses in a fine row on the other cardboard, farm 2. I asked a 6 year old child, which farmland has more grazing land? First he answered farm 2, the he hesitated. Then I asked a 9 year old child the same question, he answered, both have the same grazing land. Analysis: According to Piaget cognitive and language development theory the first child will be in the preoperational stage, and the indication of his answer shows that he is in transitional stage. The second child's answer indicates that he is in concrete operational stage, because in this stage children have the ability to conserve the physical characteristics of objects, therefore this is mastery indication.
