An indispensable tool of any meaningful application development endeavour is an inte-grated development environment (IDE), and the same naturally applies for coding in Java programming language. There are many IDEs that are readily available to be used, though not all of them are well suited for elementary programming courses. BlueJ stands for a prominent exception here and its usage at hundreds of universities world-wide can be taken as a sound proof of this. The BlueJ value offering and traits are undisputable. That being said, we have to acknowledge that it is not perfect. One can iden-tify enhancements that need to be implemented for the tool to better support teaching ob-ject-oriented programming. The goal of this thesis is to identify the most prominent shortcomings of the BlueJ interac-tive mode and to design an implement features that will address them.

[pt] Nesta dissertação, os documentários Peões e Entreatos, lançados em 2004 e dirigidos por Eduardo Coutinho e João Moreira Salles, respectivamente, servem para uma discussão acerca da complementaridade de suas propostas bem como da possibilidade de vê-los como um filme único. Com modos de representação predominantes diferentes - o cinema-verdade e o cinema de observação -, os filmes se articulam relacionados a um eixo principal de ligação, a trajetória de um operário, um homem comum entre milhares de outros igualmente anônimos, que chega à Presidência da República. É através deste eixo cronológico, que vincula intimamente os dois filmes, que serão levados em consideração os principais teóricos do cinema documentário. / [en] In this thesis, the documentaries Peões and Entreatos, released in 2004 and directed by Eduardo Coutinho and João Moreira Salles, respectfully, are the backdrop for a discussion about the complementarity between these two works. After all, with predominantly different ways of representation - interactive mode and observational mode- , the films articulate related to a main connection, Lula, who was a presidential candidate at the time. The films were shot simultaneously, as part of a same project from Videofilmes, fulfilling an old wishthat the directors would work together, but respecting their personal characteristics. Thus, having such different perspectives, how can they be so closely related? To answer this question, the main theorists of cinema will be considered, considering the characteristics of one another and how to identify if the films can be translated into one.
