Book excerpt: The outbreak of the COVID-19 pandemic has created challenges and opportunities for both teachers and students. In many countries, online teaching was something new, never experienced before. Therefore, everyone had to start from scratch. The articles in this proceeding provide the experiences, challenges, and strategies that L2 teachers and students had during the recent emergency remote teaching. Four main themes were covered: 1) online L2 learning curriculum and materials development, 2) L2 learning and acquisition in a virtual learning environment, 3) online L2 testing, assessment, program evaluation, and 4) teacher and students’ critical reflections on online L2 teaching and learning practices. Written by L2 teachers and teacher educators, we dedicate this proceeding to all L2 teachers and teacher educators who continue trying to maintain high-quality L2 education during and post-pandemic.
