RESUMO

Interactions in CSCLE (Computer-Supported Collaborative Learning Environments) are one of the most important visible aspects of collaboration. The analysis of these interactions can provide support for the students reflection and self-regulation processes and for the teachers activities. But to perform the analysis process, it is important to discover and register the context where each interaction has occurred, in order to understand the meaning of user interactions. However, there is a lack of methods and tools for Interaction Analysis in CSCL that consider: (1) the context where the interactions have occurred; (2) the different needs of feedback from the point of view of teacher and students; and (3) the necessity of contextualized historical information to produce more complete reports for students and teachers. In this light, aims to provide good quality just-in-time feedback for both students and teachers, this thesis presents a Context-Based Process for Interaction Analysis that structures the interactions, taking into account the context where the interactions occur. After that, it stores the interactions in a multidimensional repository called LIM (Learning Interaction Memory) and, finally, uses analytical queries to explore and analyse the stored information from different perspectives (dimensions), according to the userâs needs. This thesis also presents a Context-Based Analytical Environment called SmartChat+: an environment for collaborative discussions of specific subjects that performs the defined Context-Based Process. In fact, the initial experimentation of this environment is detailed and the results of the exploratory studies are discussed, indicating the feasibility of the proposed process and its potential to support effective learning.
