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.

These proceedings present a selection of papers from the ICTTE 2021 conference. While face-to-face classroom instruction is brought back, there are a lot of lessons learned from the COVID-19 pandemic that schools, teacher training and education institutions, and government have to take into account. There is a need to reconsider what additional knowledge and skills pre-service teachers and in-service teachers need to be prepared for to anticipate such a similar unexpected situation in the future. Additionally, there is also a need to listen to in-service teacher experiences during the emergency remote teaching and integrate the positive lessons that they have gained, such as the use of technology, into the current post pandemic face-to-face classroom instruction. This proceeding is designed for teacher educators, researchers, in-service teachers, and pre-service teachers in the field of language education, math and science education and social science education, who are interested in these topics.
