The existence of Sundanese in schools at this time is not included in the main subject but its existence is a subject of local content. This is one factor in the lack of student interest in Sundanese and its use is rarely done by students. Thus, the most relevant implementation to overcome this problem is to combine Sundanese learning with environment-based learning into environment-based Sundanese learning. The purpose of this study was to explore teachers’ perceptions of learning Sundanese as one of the local content subjects in elementary schools during the covid-19 pandemic. Data were collected through online questionnaires (google form) and semi-structured interviews with Sundanese language teachers and classroom teachers in West Java. Data were analysed using thematic analysis. Three main themes were found, namely outdoor learning design, communication, and positive emotions. This study shows that learning Sundanese based on the environment by respondents can be carried out both online and offline, so as to minimize the impact of COVID-19 on Sundanese language learning in schools.
