Although the command language to produce an aswer to be sent to TRAKLA-server as well as the exercise and answer formats for given WWW-TRAKLA exercise are simple, errors occur. To avoid these errors and to give a student an interactive tool for solving the exercises, a graphical editor is needed.
The TraklaEdit is a Java applet that eliminates the errors involved in the server command language and in the internal format of the given answer. It is platform-independent, interactive graphical editor which runs on a Web-page in order to present exercises graphically, offer tools for solving the exercises, record the intermediate steps the student does to solve the exercise, and finally generate the answer using the required command language. The student does not need to know anything about the server command language or the given format of neither the exercise nor the answer.
In order to take a quick demonstration of the graphical editor there is a few exercises to demonstrate the available features of the TraklaEdit.
