Children's Understanding of the Geometric Transformation of Rotation About a Point.
McGlone, Virginia Elizabeth
In this study Piaget's method of the clinical interview was used to examine children's understanding of rotation about apoint at three age levels (6, 7, and 8). In two half-hour sessions, subjects (N = 108) were given four tasks: (1) an adaptation of Piaget's locus and circular motion experiment, and tasks concerned with (2) the circle as a locus of points, (3) group properties of a set of four rotations, and (4) angle of rotation, the radius of each point, and orientation of a figure after rotation. As measured in this experiment, children's understanding of each task increased with age. On one angle task, six-year-old boys performed significantly (p = less than .01) better than girls; no other sex differences were discovered. Results of the experiment support Piaget's analysis, both with respect to successive acquisition of understanding and with regard to the distinction between perceptual and representational space.
