The purpose of this study is to explore the experiences of non-face-to-face online classes and blended learning classes of elementary school teachers in the COVID-19 situation, focusing on the standard frame of class expertise, and to investigate the perceptions of elementary school teachers on the direction of teaching for the “With Corona” era. The participants of the study were 26 teachers who had teaching experience in elementary schools in 2020 and 2021. An open-ended questionnaire was conducted on the experience of class operation in the context of COVID-19, and 6 out of 26 teachers were interviewed for specific questions about the questionnaire and identifying what direction these elementary school teachers believed future elementary classes should maintain from the present conditions. As a result of the study, in the COVID-19 situation, all teachers felt like they were returning to the beginning teachers, and they tried to respond to the new professional knowledge required by the times. In addition, the classroom environment and teaching methods that were so familiar came to feel unfamiliar, and teachers took on more and more responsibility for the professionalism of non-face-to-face online classes and blended learning classes. Overall, the elementary school teachers in this study held common perceptions about the direction of the “With Corona” educational policy which sought to normalize education conditions in schools, but teachers also recognized the potential of the new opportunities afforded for teaching and learning by envisioning a class in which offline and online classes could coexist. These findings have implications for the need to continue to consider how to effectively support teachers and students to engage in blended learning environments in the post-COVID-19 era.
