Young people bring their own media and literacy practices to school as an important part of their identity, taste and social life. These practices are changing the media ecology of schools, making the physical boundaries of schools more permeable and creating new, unofficial spaces at school. During peer-based learning, the enhanced media practices of students often get incorporated into the school environment and the learning process in different ways. In this article the author especially highlights youth media production practices, which may relate to school in three different ways: they may be school community-based practices, curriculum-based practices or out-of-school practices. This study shows how these practices create a dialogue between informal and formal learning and make space-time at school more dynamic and hybrid.
