Abstract
This paper describes an investigation into how the use of Logo affects children's basic knowledge of angle. It shows that teachers should not assume that unstructured use of Logo with a minimum of teacher intervention will have a beneficial effect on children's knowledge of angle and how it is measured. It appears to be the case that children make erroneous adjustments to their conceptual knowledge of angle in order to accommodate the results of an acquired procedural interaction with the computer.
