We expand the theoretical perspective based on the notions of description and conflict, which was previously used to the learning of functions and calculus, to the learning of deductive geometry supported by Dynamic Geometry (DG) environments. Based on prior studies on functions and on the potential role of a DG software, we analyze a case study…

Peer reviewedStraesser, Rudolf – International Journal of Computers for Mathematical Learning, 2001
Discusses geometry and Dynamical Geometry Software (DGS). Analyses the way DGS-use influences traditional geometry. Highlights changes in the interactions between geometry, computers, and DGS and human users, focusing on changes in the teaching and learning of geometry. Concludes that DGS deeply changes geometry if it is taken as a human activity…

Belfort, Elizabeth; Carlos Guimaraes, Luiz – International Group for the Psychology of Mathematics Education, 2004
In this paper we analyze instructional materials supported by a Dynamic Geometry software, which were produced by teachers during an in-service training program. We discuss illustrative examples, as well as the outcomes of the critical discussions that took place during the presentations of these materials by the teachers. In order to analyze…

McDonald, Joseph P. – 1985
This report summarizes the proceedings of a conference held at the Harvard Graduate School of Education which focused on the conceptual distinction between microworld software and expert system software in education. Microworld software is defined as software which lacks a specific teaching and learning agenda, and expert systems as software that…

Peer reviewedKaljumagi, Eric A. – Journal of Computers in Mathematics and Science Teaching, 1992
Presents the results of a preliminary investigation into the feasibility of teachers constructing their own animations for the mathematics classroom using computer animation tools. Provides examples of animation constructed using "Ani ST" and "Mathematica" programs. Concludes that computer animation has potential to be a…

Beyond the Evident Content Goals Part I. Tapping the Depth and Flow of the Educational Undercurrent.
Peer reviewedDugdale, Sharon; Kibbey, David – Journal of Mathematical Behavior, 1990
The first in a series of three articles, successful instructional materials from a 15-year software development effort are analyzed and characterized with special attention given to educational experiences intended to shape students' perceptions of the fundamental nature, interconnectedness, and usefulness of mathematics. The software programs…
