Children's Learning of Geometrical Concepts Through Logo.

This exploratory study aimed to investigate some elements of geometrical concepts that children learn through Logo programming. A test designed to probe children's conceptions of three components of length and angle was administered to 84 children who had learned Logo for one year and 92 who had not. The components of the concept of length were (a) length conservation, (b) length combination, and (c) length measurement. The components of angle were (a) right angle conservation, (b) angle conservation, and (c) angle measurement. Analysis of data using a linear modeling technique indicated a consistent trend toward a sex-treatment interaction.
