Anti-Bullying in the Digital Age: How Cyberhate Travels from Social Media to Classroom Climate in Pre-Service Teacher Programmes

This article examines online hate as a driver of cyberbullying and a barrier to inclusive schooling, integrating theoretical, philosophical and methodological perspectives. We approach hate speech as communicative practices that legitimise discrimination and exclusion and, once amplified by social media affordances, erode equity, belonging and well-being in educational settings. The study adopts a qualitative, exploratory–descriptive design using focus groups with pre-service teachers from initial teacher education programmes across several Chilean regions. Participants reflected on the presence, trajectories and classroom effects of cyberhate/cyberbullying. Data were analysed thematically with ATLAS.ti24. Findings describe a recurrent pathway in which anonymous posts lead to public exposure, followed by heightened anxiety and eventual withdrawal. This shows how online aggression spills into classrooms, normalises everyday disparagement and fuels self-censorship, especially among minoritised students. The analysis also highlights the amplifying role of educator authority (tone, feedback, modelling) and institutional inaction. In response, participants identified protective practices: explicit dialogic norms, rapid and caring classroom interventions, restorative and care-centred feedback, partnership with families and peers, and critical digital citizenship that links platform literacy with ethical reasoning. The article contributes evidence to inform anti-bullying policy, inclusive curriculums and teacher education by proposing actionable, context-sensitive strategies that strengthen equity, dignity and belonging.
