Schumann, Heinz – Journal of Computers in Mathematics and Science Teaching, 1992
Presents the geometric, software-ergonomic, and educative standards for interactive graphics systems envisioned for planimetric constructions and calculations in secondary mathematics instruction. Describes the geometric-didactic potentials of the MS DOS-Version 1.6 of CABRI-Gomtre which is an Intelligent Tutoring System with the possibilities for…

King, James – Journal of Computers in Mathematics and Science Teaching, 1988
Explores the production of shadows for drawings using the LOGO computer language and Affine Geometry. Explains the methodology of the shadowing and lists the Affine Turtle procedures. Provides for different versions of LOGO. (MVL)
Descriptors: College Mathematics, Computer Graphics, Computer Oriented Programs, Computer Uses in Education

Natsoulas, Anthula – Journal of Computers in Mathematics and Science Teaching, 1989
Gives definitions of taxicab geometry and the MacDraw format for graphing. In the world of taxicab geometry, movement through the plane is along horizontal and vertical paths. Describes specific application to conic sections, including circle, ellipse, parabola, and hyperbola. Lists five references. (YP)

Thomas, David A. – Journal of Computers in Mathematics and Science Teaching, 1989
Discusses dimensionality in Euclidean geometry. Presents methods to produce fractals using LOGO. Uses the idea of self-similarity. Included are program listings and suggested extension activities. (MVL)
Descriptors: Computer Graphics, Computer Oriented Programs, Computer Uses in Education, Fractals

Niess, Margaret L. – Journal of Computers in Mathematics and Science Teaching, 1988
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)
