employed as a collaborative tool or as a medium of artistic or social criticism, has been introduced in a mathematics course for online pre-engineering students. The objective of this innovation is to integrate the communication and the subject’s contents and to check whether a better level of communication between students and professors improves the acquisition of basic mathematical competencies. As a result of this study, we put forward a model for the analysis of the online interaction, as well as a classification of students in relation to the use of the communication tool.
