The research outlined in this paper is based on the convergence of two conceptual frameworks that guide the transfer of knowledge and skills from traditional teacher education, which focused on teaching in single classrooms, to open networked learning environments that include both inter-institutional teaching and learning and local and global community engagement. Through these frameworks, schools can be extended in terms of time, space, organisation, and capacity. This will be demonstrated on the basis of New Zealand research in inner-city urban environments and Canadian research in rural Newfoundland and Labrador. There are implications for the professional education of teachers from schools that have the capacity to engage with global learning environments, including new ways of relating to learners, learners' parents, networks, and communities. Several of these implications will be analysed in the conclusion of the paper and should generate discussion that will inform current and future research.
