"The ability to express oneself clearly, understand others, and adapt to diverse contexts is essential for academic success, meaningful relationships, professional growth, and global citizenship. For senior high school students, learning to communicate well in English provides a strong foundation not only for higher education and future careers, but also for participation in a rapidly changing, interconnected society. Speak, Write, Connect: A Worktext on Effective Communication for Senior High School Across Contexts responds to this need by aligning with the Department of Education''s 2025 Strengthened Senior High School Curriculum for Grade 11. It offers authentic, relevant, and meaningful activities that develop students'' communicative competence in English across four key contexts: personal and interpersonal, social and cultural, academic and training, and professional and work settings. The worktext is designed to guide learners in becoming responsible, adaptive, and globally competent communicators. "
