Transformative Learning and Social networks. Workplace, School and Informal Educational Settings Claudio Melacarne University of Siena Loretta Fabbri University of Siena Abstract In recent decades, the emphasis of the scientific debate has greatly shifted to online learning experiences, highlighting their power and criticalities. Various researches have been focused on the relationship between TL theory and online environments, defining new research objects and extending TL traditional issues. We used Transformative learning theory to plan our research project and focus the research on three principal questions. Can social networks support TL processes, given that many people belonging to developed countries use social networks daily at work, at school and in the every day life? Which online setting conditions can foster the development of more inclusive, discriminating, open and reflective meaning perspectives? Finally, how do the transformational potentiality of social networks change in the three contexts? The methodological approach was mixed: qualitative and quantitative methods. Three communities were involved in the research: doctors, students and adults.
