Piagetian Video Case Study
I began Michael-Joseph with Piaget’s task Conservation of Numbers by lining up two identical rows horizontally of three small stick pretzels. I asked, “Do both rows have the same number of pretzels?” He replied “yes”. Then I lengthened one row by placing one extra pretzel and asked him, “Now does one row have more pretzels in it than the other row?” He answered, “yes”.
Conservation of Matter was the next task. I placed two identical balls of play dough (same size and shape) in front of Michael-Joseph. I asked, “Do these two balls have the same amount of play dough in them?” He replied “yes”. Without adding play dough, I changed the shape of one ball by flattening it. I asked him if he now thought that one of the play dough’s had more? His response was “no”.
In conducting the Conservation of Length, I aligned vertically two unsharpened pencils (same length) in front of Michael-Joseph and asked, “Are these two pencils the same length?” His reply was “yes”. Without changing the size, I moved one pencil to the right and asked, “Now are the two pencils the same length?” Michael-Joseph answered “yes”.
Conservation of Volume was the last task I conducted on Michael-Joseph. Measuring cup he observed me pour 1 cup of water into two identical glasses and dropping two identical play dough balls in each glass. I asked him if the balls moved the same amount of water in each glass he answered “yes”. Then I took one ball and changed its shape and placed it back into the cup of water. “Will the balls still move equal amounts of water in each glass?” Michael-Joseph answered, “yes”.
Piaget’s tasks clearly represent Michael-Joseph at the concrete operational stage of cognitive development. When conducting each task he was able to solve each task in a logical fashion. During the tasks his recognition of the physical world aided him to re...
