<![CDATA[This study aims to develop a Pocket Book of Daily English Expressions for boarding school students in the pesantren context to improve students’ speaking skills in everyday communication. The study employed a Research and Development (R&D) method using the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages. The participants involved students from grades 7, 8, and 9 in an Islamic boarding school in Cimahi, West Java, Indonesia. Peer facilitators from grades 8 and 9 were trained to assist the implementation process. Data were collected through classroom observation, progress evaluation, post-tests, and student feedback. The findings showed significant improvement in students’ speaking performance after four weeks of implementation. Speaking participation increased from 45% to 89%, vocabulary mastery improved from 40% to 86%, and students’ confidence in speaking English rose from 38% to 85%. The contextual materials provided in the pocket book helped students practice English expressions related to dormitory life, making learning more meaningful and practical. In addition, the peer-facilitator approach created a collaborative learning environment that encouraged active communication. The study concludes that the developed pocket book effectively supports English speaking practice in pesantren environments and contributes positively to students’ communicative competence, motivation, and confidence in using English for daily interaction]]>
