Web-based learning is currently a hot research and development area. The benefits of web-based learning are clear at hand: learners can overcome the constraints of time, distance, and boundaries. On the other hand active learning provides a powerful mechanism to enhance depth of learning, increase material retention, and get learners involved with the material instead of passively participate in the learning process. In this paper, a research using Java2D as an example of web-based active learning tools in computing courses will be given. In addition, an evaluation of the tools in practice is given, which shows an improvement in the learners performance in classes.
