This paper presents TrAVis (Tracking Data Analysis and Visualization Tools), a Web-based system, implemented to assist the participants in the learning process in analyzing the tracking data of Computer- Mediated Communication activities. While most of the existing systems in the same genre are exclusively dedicated to the teachers and only a few are accessible by students, TrAVis is objectively designed and built for both teachers and students. TrAVis is a technological solution that enables the students to monitor in real-time the individual or group activity. It is also considered a “reflective tool” that helps students analyze their own activities in relation to those of others. This paper focuses on (a) the visualization of students’ tracking data to enhance self-monitoring process and (b) the experiment we have conducted in an authentic learning situation. It also discusses the feedbacks we received from the students regarding their perception on the usability and utility of TrAVis.
