RESUMO

Distance education is characterized by the partial or total absence of the "presential" element in the teacher-student relationship, that is, teacher and student are far ftom each other and need to use a communication channel to media te the interaction. In the last few years, distance education based on environments that use Internet as a communication channel has grown larger and larger. These environments make available many tools that support communication through the Internet (for example: chat, e-mail, newsgroup). In the literature, many articles relate the large amount of work needed by the teacher of a distance course to accompany properly the development of the students. In order to help the teacher with the task of accompanying the development of the students in a distance course we developed the interface agent Chapa, described in details in this dissertation. Chapa s focus is on helping the analysis of participants contributions to a chat session that took place in T elEduc, a supporting environment for distance education. In order to do that, it is capable of selecting which messages are more interesting to one user, allowing him to analyze only a ftaction of the total number of messages that exist in a session. lt is able to do this selection based on a specific data dictionary which is built for each user by means of learning techniques inherent to the technology of interface agents. In this work, some preliminary tests were done with Chapa. However, even though the results were very positives, it is still necessary to realize more tests in real world courses in order to better proofChapa s effectiveness
