iTimeline: Uma Ferramenta Visual para Identificação e Acompanhamento das Interações Sociais em Ambientes Virtuais de Aprendizagem

Abstract

Nowadays, with the great use of Virtual Learning Environments in teachinglearning institutions, it is necessary that the teachers can follow the interactions of the students in the Distance Education courses. However, some AVAs do not have specific tools to assist the teacher in obtaining information on the students' social interactions. This makes it difficult for the teacher to perceive and follow up in these virtual environments. In this sense, with the advent of Data Visualization, a relevant and widely used area of research in several areas of knowledge to analyze and visualize data. This research describes a model of identification and representation of students social interactions using LMS Moodle visualization techniques. With the iTimeline tool developed in this research, the teacher can visualize the interactions of his students in real time within the LMS and adopt measures that promote social insertion, thus collaborating and encouraging teaching and learning. iTimeline extracts the data contained in the discussion forums and messages recorded in the database and uses the structure of graphs and graphs, as a basis, to present the information about the interactions of the students and visually displaying them to the teacher. In order to validate this research, a case study was carried out in which its possibilities of use and validation were investigated by analyzing the data in a class of a Distance Education course of a Public Institution. Simulated and real experiments were performed, so it can be concluded through the tests that the visualization of the data through graphs and graphs in LMS using Multiagent Systems, presented the relevance of this research.
