The purpose of this research is to describe the implementation of the Cooperative Learning strategy in developing students’ writing skills at Ma’had Aly Lirboyo and Modern Darul Hikmah Islamic Boarding School Tawangsari. The subjects of this research were first-year students (S1) at Ma’had Aly Lirboyo and seventh-grade students (ninth MA) at Modern Darul Hikmah Islamic Boarding School Tawangsari. The participants were twenty students selected through purposive sampling based on their Arabic writing ability. This research used a qualitative descriptive method. The research instruments were observation, interviews, and documentation. Data were collected through observing learning activities, interviewing teachers and students, and analyzing students’ writing documents.
