Dynamic Geometer's Sketchpad
Geoemter's Sketchpad is a dynamic geometrical software, letting teachers
use computers to demonstrate and visualize mathematics concepts to students.
Usually, in traditional teaching about geometry, students will use paper
and pencil to learn and teacher will use chalk and blackboard to
teach geometry. Because of its dynamic exploration property, Sketchpad
can be used to explore mathematics subjects such as algebra, geometry,
trigonometry, calculus, even science. Especially, it allows for dynamic
explorations in geometry so that students can see the changes in the figures
when they manipulate them. When Using GSP software with computers like
an electronic blackboard, students can instantly and dynamically draw points,
angles or lines, experience the dynamic change of geometrical concepts,
and construct the mathematical understanding form their exploring without
wasting to redraw figures to calculate and compare them.

Examples of using GSP in mathematics
Examples from Internet
Teachers' Resources for knowing more about GSP
Java Sketchpad is a software/language that lets teachers and students can
manipulate and interact instantly via internet without GSP software. Teachers
can use Java Sketchpad to demonstrate geometrical concepts and works
published to Internet for students without special software except browsers
(like IE 5.0, Netscape 4.0 later). Teachers can integrate this kind of
examples for students into their mathematics curriculum in order to provide
students' more hand on experience and activities to experience mathematical
concepts in person. See the
site of Java Sketchpad for more details.
Java Applet is a kind of
computer language that can let users design dynamic figures. It is like
the function of Java sketchpad. Hence, Teachers can find some useful applet
files in some web sites from Internet. It does not matter that teachers
are not able to use this computer language. They can find them and then
integrate them into their instruction and curriculum, providing students
to have more opportunities to learn, more hand-on experiences to
manipulate to view the dynamic mathematical concepts in order to enhance
their understanding. Please see the following examples.
Teachers can find more and more examples in web sites through Internet
and search engines as their their
material and curriculum.
