Abstract. The study sought to investigate the extent of problems encountered and the coping mechanism of the 206 students and 22 teachers of the MSU-TCTO Senior High School in terms of distribution, submission, and collection of learning materials/modules, content-related issues in the module, student-teacher communication, learning materials and resources and flexibility during a pandemic. A researcher-made questionnaire with two parts containing checklists and open-ended questions was used. The data obtained were analyzed using the mean rating for the problems encountered, and the coping mechanisms were also identified. This study found that students and teachers rarely encountered problems with distributing, submitting, and collecting learning materials/modules and student-teacher communication. The students sometimes encountered problems with content-related issues in the module, including a lack of examples provided in the module and undetailed and unexplained lessons. In terms of learning materials and resources, they sometimes encountered problems such as poor internet connection, and in terms of flexibility, they experienced emotional stress during a pandemic. The teachers rarely encountered problems with these variables. Other problems among senior high school students and teachers were the lack of focus and the numerous modular activities. Teachers' and students' common coping mechanisms were time management and taking breaks during the pandemic.
