A mediação de um agente pedagógico na aprendizagem colaborativa de inglês como língua estrangeira

This is a quanti-litative case study that parts of theory sociocultural principles applied to Second Language (SL) and Foreign Language (FL) Acquisition and studies in Computers in Education in order to investigate the effects of a pedagogical agent's (PA) mediation with specific mediation strategies in English as a foreign language (EFL) collaborative learning in a virtual environment. From the theoretical framework developed, the methodology of this research involved not only the development and application of a sequence of activities using technology in EFL collaborative tasks, but mainly in the development of a PA integrated into a textual mining tool capable of doing interventions in reading discussions in a chat room. The context of the research consisted of a class of 25 graduate students in English Language and Literature in a federal university of southern Brazil. First, students answered a questionnaire that aimed to establish the profile of these learners in the use of language and technology. Data collection took place over 6 classes in the computer lab, where students did reading discussion collaborative tasks in English in a chat tool with the mediation of the PA. After the assignments, students responded to questionnaires that sought to investigate their perceptions of the role and use of the PA in carrying out the tasks and in their learning. The task interactions, the use of the PA's functions and the data from the questionnaires were analyzed in search of the PA's mediation on students' learning and motivation. With these results, the present study was intended to contribute to the field of Computers in Education for the research on the impact of PAs in FL learning, suggesting solutions to improve Computer Supported Education. In the area of SL/FL acquisition, this study aimed to bring new data on studies of collaborative tasks by investigating the interaction with the PA as a new element for computer-mediated communication in language learning.
