Anxiety is a significant issue in English as a Foreign Language (EFL) classrooms, impacting learners' performance and overall language acquisition. This theoretical review examines recent research findings and effective techniques for reducing anxiety in EFL settings. Drawing on qualitative methodologies and empirical studies from the past five years, the review highlights various factors contributing to anxiety, including low self-esteem, fear of mistakes, and pressure from peers and teachers. The Foreign Language Classroom Anxiety Scale (FLCAS) emerges as a valuable tool for measuring anxiety, focusing on exam anxiety, communication anxiety, and fear of poor grades. The review identifies several strategies to alleviate anxiety, such as creating a supportive environment, delaying error correction, providing ample speaking practice opportunities, and incorporating relaxation techniques. Additionally, interventions like game-based learning, music instruction, and cooperative learning activities demonstrate promise in reducing anxiety and enhancing motivation among EFL learners. The review underscores the pivotal role of teachers in mitigating anxiety by offering effective feedback, facilitating speaking practice, and fostering a welcoming classroom environment conducive to language acquisition. Ultimately, the review emphasizes the importance of understanding and addressing anxiety to promote successful language learning outcomes in EFL classrooms.
