In this research, a field study is carried out about the sociocultural reality of writing by means of msm in adolescent Deaf students from a qualitative- interpretative approach. The study applies principles supported by grounded theory and the continuous comparative method by Glaser & Strauss (1967) and Strauss & Corbin (2002), as well as Murcia & Jaramillo (2000) proposals on ethnographic complimentary. The research design encompasses three moments: preconfiguration, configuration and reconfiguration. From the results have emerged the following: adolescent Deaf students’ spontaneity in writing using msm, they got identified with this new form of expression which provides them free coding and style. All these allow us to consider a set of criteria about the writing process in adolescent Deaf students which implies that the use of msm can be thought as a tool and/or instrument to facilitate knowledge construction in cognitive, social and cultural realms.
