Learners are increasingly accessing free online and open resources, tools, and spaces where they can develop their language skills beyond the classroom, alone, or in collaboration with others, and often whilst engaging in purposeful and enjoyable activities. Teachers need to find ways to explore and connect these activities productively with the formal learning that they design for their students, as shown in many of the contributions in this volume. This collection is addressed primarily to foreign and second language teachers in secondary and tertiary education. Authors were asked to provide sufficient context and detail about their projects to enable other practitioners to replicate or build upon the activities described in each case study. Whilst these are not research papers, the projects here included are often the result of pedagogical research, engagement with open education, and extensive experience of language learning and teaching. This volume includes: (1) Introduction to New Case Studies of Openness in and Beyond the Language Classroom (Anna Comas-Quinn, Ana Beaven, and Barbara Sawhill); (2) An Inclusionary Open Access Textbook for Portuguese (Carlos Pio and Eduardo Viana da Silva); (3) Creating and Implementing Open Educational Resources for the Spanish as a Heritage Language Classroom (Evelyn Durán Urrea and Jocelly G.
