Presents results of action research which had the goal of producing concepts and topics that would permit students to get creatively engaged in mathematical analysis and problem solving. The method used, called Turtle Geometry,'' is concerned with programming a moving point to generate geometric forms. (DT)

Following a brief introduction to the LOGO programing language, describes its use in a sixth-grade classroom. The situations described illustrate students' growth while the choice of the situations illustrates teachers' growth. (JN)

Presents three activities in which students learn about and construct star polygons using the LOGO programing lanaguage. A list of suggested extension activities is included. (JN)

Described are four hour-long sessions of children working with the definition and use of a procedure for triangles in Logo programming. The conclusion is that turtle geometry is not a trivial activity. (MNS)

PROLOG is a relatively new programing language with graphics capability. In addition, the language has a declarative rather than a procedural structure. Two programs illustrating use of the language in the mathematics classroom are presented. (JN)

Describes a project in which 11- to 13-year-old children used their LOGO programing experience to assist them in investigating a mathematical topic. Students initially drew frieze patterns on graph paper and then wrote LOGO program. Implications of the project for mathematics instruction are noted. (JN)

Considers activities that use LOGO to slide, turn, and flip the "turtle." Uses non-LOGO tools such as cutouts, pattern blocks, and tangrams to enhance the motion work. Provides examples and programs with explanations. (MVL)

Described is a year-long study of the way a group of six 12-year-old children went about solving a special class of geometric problems using a computer and a limited set of LOGO programing tools. Examines solution strategies deciding whether those strategies led to insights about mathematical relations. (Author/MVL)
