This volume is an important output of the ASSESSnet, an EU-funded project that aimed at investigating assessment practices in Virtual Exchange (VE) projects in Foreign Language (FL) courses at tertiary level. It starts with the discussion of selected aspects of VE and assessment design, and a summary of ASSESSnet project results. The following chapters present real-life examples of planning and administering assessment in VE projects in diverse educational settings. The descriptions of case studies are often supplemented by concrete examples of task descriptions, assessment rubrics, self-assessment prompts, and examples of student outputs. This volume is produced for practitioners by practitioners and may be of interest to teachers, teacher educators, school authorities and policy makers interested in introducing VE or improving the quality of the existing projects.
