Learning and teaching object-oriented programming are still perceived as being difficult tasks. This paper presents AGUIA/J, a pedagogical tool for interactive experimentation and visualization of object-oriented Java programs. The approach is based on having a graphical environment for experimenting a set of user-developed classes where objects of such classes can be created and controlled interactively. The main innovative aspects of the tool comprise the visualization of objects in widgets that take different forms according to their classes and state, a mechanism to address the query-command separation principle, and the capability of runtime adaptation of the objects in the workbench to new versions of their classes. An experiment using AGUIA/J as courseware in pilot lab classes has resulted in higher approval rates for the involved students, as well as significantly lower drop-out rates.
