Abstract
In recent years, the use of ICT tools for learning of mathematics received a lot of attention. New computer programs include digital chapters for existing schoolbooks, Java applets, dynamic software for geometry and statistics, computer algebra systems, computer aided testing and assessment systems, and many more. In this paper we will focus on the development and use of Java applets for learning and practising algebra and calculus at secondary school level. We have explored in what ways applets can help student to develop algebraic understanding and algebraic skills. Especially applets that provide feedback with scoring facilities and that are fully integrated in a learning environment with which students and teachers are familiar have great potential. Of course, teachers should be able to create exercises and tests based on their own ideas: the customizable SCORM compliant Java applet generator makes this possible. We will discuss our experiences from development work and classroom tests during the GALOIS project.
