Current and future computerized systems and infrastructures are going to be based on the layering of different systems, designed at different times, with different technologies and components and difficult to integrate. Control systems and resource management systems are increasingly employed in such large and heterogeneous environment as a parallel(More)
This paper presents a technological and conceptual support to formative assessment at Learning Management Systems. The proposed model aims to support the formative assessment at the distance education domain, emphasizing the formative assessment of online collaborative learning activities. The model explores computational technologies to provide a more(More)
s: Research in Education has evidenced that effective learning happens when students have the control of their learning. Teaching metacognitive skills in set with continuous learning assessment and the respective feedback to student are essential in this process, in way that student can learn how to learn.

This article tries to underscore the importance of developing infrastructure systems for learning and education based on intelligent agents structured as P2P (peer-to-peer) systems. As part of this effort is presented a model where concepts belonging to ontologies are extended with organizational information to represent explicitly the social situations in(More)
Pharos is a collaborative application which enables users to share document annotations. Annotations of a same subject are stored altogether in channels, and channels are replicated to improve performance. What characterises data replication in a collaborative application like Pharos is the way users see data. If, for instance, mutual consistency is(More)
