Due to the global outbreak of coronavirus disease (COVID-19), new regulations require students to study from home so that students must be able to study independently. This study aimed to analyze teachers' perceptions of self-directed learning (SDL) and SDL components that can be identified from online learning activities assigned by teachers during the COVID-19 pandemic. This research was designed in the form of embedded mixed-method research. An English teacher at a high school was selected as a participant. Furthermore, data were collected through questionnaires, observations, and classification tables. The results showed that: 1) with a score of 4.00, teachers perceive themselves as "knowledgeable" about SDL knowledge, with a score of 3.57, teachers perceive themselves as "expected" or often carry out learning activities that support SDL, with a score of 3.88, teachers assessing the impact of SDL as “influential” on students, 2) components of SDL reflected through online learning activities assigned by the teacher are “developing a sense of belonging to students in learning” and “developing student self-monitoring” and self-management.” Thus, teachers perceive SDL positively, and there are two components of SDL promoted by teachers' online learning activities.
