This collection of papers, consisting of 39 delegate contributions and three keynote articles from "New directions in telecollaborative research and practice: the second conference on telecollaboration in higher education" hosted by Trinity College Dublin in April 2016, offers a window on a rapidly evolving form of learning. Telecollaboration is used in many formats and contexts, but has as a defining feature the ability to unite learners from classrooms around the world in meaningful computer-mediated tasks and activities. This cross-disciplinary overview discusses telecollaboration in support of language and culture, teacher training, student mobility, and other disciplines and skills from a range of analytical perspectives. It will be of interest to anyone working in HE as an educator, researcher, educational designer, mobility officer, decision maker or administrator.
