Abstract

This study aims to understand how English Preparatory Schools (EPS) students perceive CLIL and the challenges they encounter. Ten participants were selected through purposive-convenience sampling. Data were gathered via online surveys and semi-structured interviews conducted through Google Meet. The findings reveal that while students generally view CLIL positively, they face significant challenges, primarily due to limited vocabulary and unfamiliarity with the teaching environment. Despite these difficulties, CLIL was found to enhance language proficiency, especially in listening skills, and fostered self-confidence and cultural awareness. However, the dual demands of learning content and language simultaneously led to mental exhaustion and struggle with technical terminology among these students. The study suggests that CLIL can be effective in improving English proficiency, but it also highlights the need for tailored support, such as vocabulary-building strategies and teacher training, to address the challenges students face. These findings have implications for curriculum development and pedagogical practices in CLIL programs.
