In this brief introduction we frame the special issue on “Orchestrating communities, ubicuity, time and space: International experiences in the use of educational technology.“ It constitutes the result of the “International experiences in the use of Educational Technology” panel session celebrated within the XXI University Conference on Educational Technology (XXI Jornadas Universitarias de Tecnología Educativa) (JUTE) in Valladolid, Spain in 2013. Every article has gone through a double-blind peer review process with the aim of ensuring not only the quality of the issue but also the adaptation of the initial presentations given in the aforementioned panel session to the rules of scientific publications. This issue brings together five of the works presented in the panel to address a number of relevant challenges in the field of Educational Technology. The topics accomplished by the articles spin around the (mis-)uses of technology in the national accreditation process of teachers in the United States; the tensions derived from the use, re-use and sharing of Open Educational Resources (OER´s) in Europe; an interpretive proposal to orchestrate the evaluation of complex technology-enhanced learning settings, and finally; a experience in the collective generation of documentaries at the Galiano Islands (Canada).
