A simulation tool to help learning of object oriented programming basics

In this paper we present the OOP-Anim learning environment. It was developed to help our students to learn the basic concepts of object oriented programming and to develop their programming capabilities using this paradigm. To achieve those goals students must practice intensively the development and debugging of programs. We believe this environment can help, since it uses animation to facilitate program understanding and error detection/correction. This debugging process has a lot of educational potential, as students can learn when correcting their own mistakes. When they reach a working solution, their experience and confidence normally improves, facilitating further learning. In the paper we describe the environment main features, some possible uses and the educational advantages associated with that utilization.
