Young Children and Turtle Graphics Programming: Understanding Turtle Commands.
Cuneo, Diane O.
The LOGO programing language developed for children includes a set of primitive graphics commands that control the displacement and rotation of a display screen cursor called a turtle. The purpose of this study was to examine 4- to 7-year-olds' understanding of single turtle commands as transformations that connect turtle states and to characterize the nature of their misunderstanding. Children were introduced to a highly simplified turtle graphics environment that included four possible turtle orientations and four legal commands. Children were then shown events consisting of an initial turtle state, a command transformation, and the resulting turtle state. They were asked to indicate the key/command involved in each event. Most children systematically misunderstood the commands. Younger ones associated each of the four commands with displacement in a particular direction and rotation to a particular orientation. Overall, most children performed much as Piaget's theory predicts. When the turtle rotated, they tended to focus on features of the final turtle state, ignoring both initial state and transformation information. When the turtle changed location, children seemed to attend to the transformation itself. Younger ones, however, tended to define the displacement from their own or the display screen's frame of reference rather than from the turtle's frame of reference. (Author/RH)
