The Role of a Dynamic Software Program for Geometry in the Strategies High School Mathematics Students Employ

Karen F. Hollerbrands 

March 2007, Volume 38, Issue 2, Page 164

Abstract:
This study investigated the ways in which the technological tool, The Geometer's Sketchpad, mediated the understandings that high school Honors Geometry students developed about geometric transformations by focusing on their uses of technological affordances and the ways in which they interpreted technological results in termsof figure and drawing. The researcher identified different purposes for which studentsused dragging and different purposes for which students used measures. These purposes appeared to be influenced by students' mathematical understandings thatwere reflected in how they reasoned about the physical representations, the types of abstractions they made, and the reactive or proactive strategies employed.
