This presentation introduces an emerging practice of teacher induction, peer-group mentoring model (PGM). This model is being disseminated throughout Finland by the Finnish Network for Teacher Induction ‘Osaava Verme’ which includes all the teacher education institutions in Finland. The peer-group mentoring model is based on the socio-constructivist view of learning and the model of Integrative Pedagogy (Tynjälä, 2008; Heikkinen et al., 2012). Based on empirical analysis of qualitative and quantitative data, the experiences of the national program will be introduced within a practice based approach. The aim of this study is to describe and analyze the Finnish practices of peer-group mentoring. The analysis is based on literature review and empirical data which was collected from group participants (n = about 400) using online questionnaires and interviews (n=14). The findings of the quantitative and qualitative data show how the PGM practices are (1.) semantically constituted (semantic space), (2.) what are the typical activities and actions (physical space-time) and (3.) how PGM strengthens the agency of young teachers as autonomous professionals (social space).
