w, and they both said there was. I then spaced the checkers out in the top row and asked them if there was the same amount of checkers in each row. They both said there was. I think my six-year-old brother knew there was still the same amount of checkers in each row because he was able to count the checkers. My eleven-year-old brother knew because he could count, and his thought is more like an adult.Reversibility is the ability to go through a series of stages and then go back through the stages. Preoperational children are unable to do this kind of thinking. They perform transductive reasoning, which is reasoning from particular to particular. They think more in terms of cause and effect. Concrete operational children are better at reversible thinking.Piaget interviewed children to prove his theories. I asked my little brother a few questions dealing with reversible thinking. I asked them why the clouds move. My six-year-old brother said, “The wind.” He was thinking in terms of cause and effect like Piaget said a child in his stage would. My eleven-year-old brother said, “The rotation of the earth.” He is thinking more logically like an adult. I asked them both whey the sun is up in the morning and the moon is out at night. My six-year-old brother said, “The earth turns a different way.” He has going in the right direction, but he has problems explaining it. This makes sense for a child in his stage. My eleven-year-old brother said, “When America is facing the sun, the sun’s out. When it rotates through the day, we end up facing the moon, so we see the moon.” He is able to explain it much better because of the stage he is in. He still had a little trouble because he does not yet think completely like an adult. I then asked them both why boats float. My six-year-old brother said, “Because it isn’t heavy, and the hole that is cut in it for the peop...
