Abstract
This paper introduces a course that I
designed for university mathematics
education majors to explore geometric
concepts and problem solving via
technological tools, and illustrates
how I organize both in-class and
after-class interactive dynamic
geometry activities using JavaSketchpad.
The use of JavaSketchpad
has been found to be effective. It covers the limited exploration of the students through the
course homepage.
The related web sites of
JavaSketchpad encourage the students
to acquire further knowledge.
The dynamic environment provided
by JavaSketchpad puts the students
in a position to visually manipulate
the geometric objects and hence
experience mathematics by seeing
it happen or making it happen. This significantly extends the students’ visualization
and spatial thinking abilities,
and facilitates their conceptual
understanding.
