This paper presents a part of our research work that places an emphasis on Tracking Data Analysis and Visualization (TrAVis) tools, a web-based system, designed to enhance online tutoring and learning activities, supported by computer-mediated communication (CMC) tools. TrAVis is particularly dedicated to assist both tutors and students in the task of exploiting tracking data of communication activities throughout the learning process. This paper focuses on the technical aspects of TrAVis, the visualization of students’ tracking data and the experiment we have conducted in an authentic learning situation.
