RT Journal Article T1 Learning Leaders: Teachers or Youtubers? Participatory Culture and STEM Competencies in Italian Secondary School Students A1 Gil Quintana, Javier A1 Malvasi, Viviana A1 Castillo Abdul, Bárbara A1 Romero Rodríguez, Luis Miguel AB Youth is increasingly learning in non-conventional contexts, such as social networks orvideo platforms, courses, and tutorials. This research aims to diagnose the role of participatory culture,digital resources, social networks, and, specifically, YouTube, in learning processes and the acquisitionof Science, Technology, Engineering, and Mathematics (STEM) skills, specifically in mathematics,also analyzing the role of youtubers and, in contrast, teachers, both learning leaders in the formationof these skills. In order to accomplish this, mixed methods (quantitative and qualitative) were used,based on a survey applied to 4845 Italian adolescents, as well as a content analysis of the videos andYouTube channel of the Italian educational influencer Elia Bombardelli, one of the most followed andbest rated in this country. Also, an in-depth interview has been applied to 12 Italian secondary schoolteachers. Among the main findings, it is highlighted that all adolescents value YouTube videos as akey resource to improve their school performance, rating youtubers better than teachers. However,it is remarkable that in the processes of learning and acquisition of STEM competencies, they preferto interact with teachers rather than with youtubers.
