Egnatoff, William J. – Journal of Computers in Mathematics and Science Teaching, 1991
Fractal geometry is introduced through examples of computational exploration of coastlines, self-similar curves, random walks, and population growth. These explorations, which include the construction of algorithms and the subsequent development and application of simple computer programs, lend themselves to self-directed study and advanced…

Fagan, Patsy J.; Thompson, Ann D. – Journal of Computers in Mathematics and Science Teaching, 1989
Discusses a classroom project for teaching conceptual meanings and functional purposes of the notations and symbols of mathematics. Describes the background of the approach based on Piaget's theory: concrete level, symbolic level, and abstract level. Lists 14 references and 4 suggested readings. (YP)

Clason, Robert G. – Journal of Computers in Mathematics and Science Teaching, 1991
A mult tile is a set of polygons each of which can be dissected into smaller polygons similar to the original set of polygons. Using a recursive LOGO method that requires solutions to various geometry and trigonometry problems, dissections of mult tiles are carried out repeatedly to produce tile patterns. (MDH)

Clason, Robert G. – Journal of Computers in Mathematics and Science Teaching, 1991
Described is a recursive LOGO method for dissecting polygons into congruent parts (rep tiles) similar to the original polygon, thereby producing unexpected patterns. A list of descriptions for such dissections is included along with suggestions for modifications that allow extended student explorations into tile patterns. (JJK)

Schumann, Heinz – Journal of Computers in Mathematics and Science Teaching, 1991
Described and evaluated are microcomputers as a tool for construction in geometry education and heuristic theorem finding through interactive continuous variation of geometric configurations. Numerous examples of theorem finding processes are provided using the prototype graphics system CABRI-Geometer. (MDH)

Dreyfus, Tommy; Halevi, Tirza – Journal of Computers in Mathematics and Science Teaching, 1991
Discussed is the classroom suitability of an open learning computer microworld centered around families of quadratic equations that provides a framework for exploring questions about parabolas to establish the link between the graphical and the algebraic representations of quadratic equations. (JJK)
