Currently, there is a situation where class sizes in general and English classes in particular are always large, leading to an overload of articles that teachers need to review every week. For teachers, pairwork activities have become a solution that brings many benefits such as increasing students' initiative, increasing students' writing practice time, reducing pressure on teachers, and developing students' writing skills in general. This study focuses on understanding students' perceptions of group activities in pairs and the research results show that students also have positive assessments of the effectiveness of this activity.
