....There are many systems for generating animations from Xtango [8] in which animations are built from scratch to Samba [9] a scripting language in which students output commands from their program that can then be used to generate an animation. Other animation tools that use scripting include GAIGS [2] and AnimalScript [7] JAWAA is most like Samba; however, in addition it has scripting commands for easy creation of data structures, runs over the web, and more recently has a JAWAA Editor for easy creation of complex objects. 3JAWAA2.0 JAWAA 2.0 is a scripting language for creating animations ....

....construction of an extensive taxonomy [11] most of these visualizers can be separated into two broad groups in relation to their use for teaching data structures. The first group of visualizers, from the pioneering systems BALSA [3] and TANGO [15] to recent e#orts such as JAWAA [10] and GAIGS [9], are powerful tools for animating and comparing di#erent algorithms. They are also useful for teaching data structures, because they provide a high level, conceptual view of how the data structures function. One limitation of these visualizers, however, is that they are either intended to give a ....

....algorithm animations and animation systems. We have included our system among the links. Others have also created Web based animation systems recently. Michail [MIC96] has developed a Java applet that implements a visual language designed for teaching binary tree algorithms. Naps and Bressler [NAP98] have ported their GAIGS system to the Web. Finally, Pierson and Rodger [PIE98] have developed a Java based animation system entitled JAWAA, that contains graphical objects that are created in manner patterned after Stasko s Samba animation system. 2.3.4 CAI containing algorithm animation The ....

....preceding frame. The alternate approach of showing the frames one at a time forces the viewer to remember the exact form of the previous configuration, which seems an unnecessary burden on the viewer. The utility of showing more than one frame at a time was already observed by Naps and Bressler [NB98] they provide an environment for showing multiple frames, which could be successive views of a data structure, or might be alternate views of the same algorithm configuration. Our perspective, which we discuss further in Section 3, is that it is essential to present successive frames within one ....
