RESUMO

In the last few years, education has been going through important changes related to the introduction of information technology in the learning process. As a result of these changes and of efforts to take advantage of the benefits provided by this technology, many systems (or virtual environments) for supporting the learning process have been developed. However, despite the great number of tools offered by those systems, many users still prefer to develop their own tools. This happens because there is a lot of diversity in teaching and evaluation techniques among different teachers and traditional learning systems are not designed to adapt to this diversity. They do not offer many possibilities for functionality adaptation and extension. This makes users unmotivated to use them and forces them to write their own applications. As an alternative to this flexibility problem, a modular, component-based framework (WebMODE - Web MOdular DEvelopment) was proposed for the development of more adaptable and extensible Web applications, especially for web-based learning systems. In addition, a software process for instantiating software applications using this framework was also proposed. This software process emphasizes the specification of the modules that form these software applications in a format independent of the technology used for their implementation. The main features of this framework are the use of design patterns, such as MVC (Model View Controller), and the use of concepts from modular and component-based systems for the development of web applications composed by modules with configurable functionalities. The WebMODE was designed as a conceptual framework and later implemented and evaluated using the J2EE (Java 2 Enterprise Edition) technology
