Abstract
This study investigates how well it works to foster students' language proficiency development by creating interdisciplinary links between the history of Kazakhstan and the Kazakh language in the Nazarbayev Intellectual Schools. The research examines how integrating language instruction with historical content enhances students' language proficiency, critical thinking abilities, and cultural literacy. It is based on the tenets of interdisciplinary education and language acquisition theory. The research methodology includes a comprehensive review of the literature on Content and Language Integrated Learning (CLIL) pedagogy, an analysis of the structure of curricula, and the collection of empirical data through classroom observations and student assessment. The relevance of integrating language learning with the history of Kazakhstan lies in its ability to promote the development of multilingualism, increase the level of language proficiency, and deepen cultural understanding among students, thereby preparing them to become informed and involved citizens in a diverse global society. The aim of the investigation is to study and apply pedagogical strategies like CLIL. These strategies help students become more proficient in language and enhance cultural understanding. Furthermore, the research elucidates the teaching approaches and optimal methodologies employed in the classroom.
