Abstract
This study explores the effects of teacher-led code-switching on students’ grammar comprehension in English as a Foreign Language (EFL) classrooms in Kazakhstan. A mixedmethod approach was employed, combining a teacher questionnaire (N = 107) and a quasiexperiment with tenth-grade students (N = 22). Drawing on Vygotsky’s Sociocultural Theory and Myers-Scotton’s Markedness Model, the research investigated whether incorporating students’ first language (Kazakh) supports grammar learning. The experimental results showed that both groups improved, but the code-switching group demonstrated slightly greater gains and reduced score variability. Survey findings revealed that most teachers consciously or habitually use code-switching and consider it effective, particularly for complex grammar topics. The study concludes that code-switching can serve as a valuable pedagogical tool, especially for learners with limited English proficiency, and recommends its strategic use in grammar instruction.
