This professional development workshop trains professors interested in implementing collaborative online international learning (COIL) projects in their classes. Participants are exposed to the main features of COIL pedagogy and gain direct experience with the tools, techniques, challenges and opportunities encountered during a COIL project. Activities are structured in four modules, and include a series of online, asynchronous activities and three synchronous, interactive meetings. At the end of the workshop participants are able to address the planning and implementation of COIL projects from multiple perspectives: technological, pedagogical, linguistic, and intercultural. Participants receive a certificate of completion via email.
