The learning process in Indonesia has predominantly been conducted online since March 2020 due to the COVID-19 pandemic. This learning mode has also influenced students' motivation in learning, especially in comprehending reading texts. This study aims at investigating how the students regulated their comprehension in reading during an online class. This study used a mixed method. The data was collected using questionnaires from 30 students and interview involving four students. The results show not all of the students could regulate themselves in comprehending English text during the online class well. Students who could regulate themselves in comprehending the English texts during the online class developed the following procedure: (1) implementing learning autonomy, (2) implementing learning focus, and (3) using critical thinking. Meanwhile, students who could not regulate themselves well were inclined to perform minimally. Since students had different ways to regulate themselves, the teacher needed to monitor the students in the online learning process so that the students could achieve a meaningful learning process. To improve students' regulation in reading comprehension, the teacher can implement suitable learning activities.
