Integrating "Geometer's Sketchpad" into a Geometry Course for Secondary Education Mathematics Majors.
Groman, Margaret W.
Geometer's Sketchpad is an interactive geometry software package used to help students learn geometry principles. Use of Sketchpad in a secondary education math course at the State University of New York (SUNY) at Oswego has allowed geometry to be taught in a dynamic manner. The paper provides three examples of how Sketchpad is used. Traditional paper folding and ruler and compass constructions are important preliminary steps to teach students, in order to prepare future teachers for classrooms that may not yet have access to dynamic geometry software. Sketchpad provides a measurement option and the ability to do the construction for a single triangle, then click and drag on a vertex to deform the triangle into many different shapes until the important characteristic of the triangle becomes clear. Student reaction to the use of Sketchpad in their geometry course was overwhelmingly positive. Many wanted to purchase copies for their own personal use and for use in their student teaching experience. Both students and instructor learned to use the software to test conjectures and constructions, and back up the theorem/proof process by using Sketchpad to ask "what if" questions. The course came closer to an ideal situation where students construct their own mathematical understandings and where the instructor is less of a depository of mathematical truth but more one of many geometrical investigators.
