  In this paper we present our experience in using visualization in mathematics
education. The experience with our university courses: "Computer tools in
matematics" and "Symbolic algebra" provides the basis for mathematics teacher
education program http://vizuelizacija.etf.rs/. The program is intended for
elementary and high school teachers. The education program deals with modern
techniques of visualization by using technologies such as GeoGegebra, JAVA and
HTML.
