This study examines the impact of multimodal integration, particularly the combination of visual and auditory elements, on EFL learning through Moroccan textbooks, specifically English Spotlight 1 and English Horizons. It investigates how these educational materials rely on visuals, diagrams, and audio tools to foster comprehension, retention, and engagement among secondary school students in Morocco. Employing a mixed-methods approach that includes both qualitative and quantitative analyses, the study evaluates the effectiveness of these features from the viewpoints of students and teachers. The results indicate that visual components significantly and positively affect vocabulary acquisition and grammatical comprehension, while auditory elements enhance listening skills and pronunciation. The research emphasizes the necessity for more advanced multimodal content in Moroccan EFL education and identifies technological barriers that impede full integration. It recommends an increased emphasis on multimodal resources in textbook development and the improvement of technological infrastructure in educational institutions.
