Teaching and Learning Vocabulary Techniques for ESL Program: BELTEI International School

The study investigates the factors contributing to poor English linguistic performance among students in three high schools such as (1) BELTEI International School (2) American Bridges International School (3) Prek Anhchanh Campus. It aims to challenge ESL students’ weak vocabulary skills, develop English vocabulary based on learners’ proficiency, and use various resources and materials to create engaging and interactive vocabulary lessons. The study uses mixed methods and the Yamane (1997) formula and purposive sampling is the method. Data was collected through questionnaires and interviews with teachers. Findings showed that students faced various learning preferences and techniques, including reading, multimedia, vocabulary quizzes, games, activities, contextual learning, writing, and group work. Solutions included interactive teaching methods, contextualized learning, proficiency-based learning, and reading, communication, and assessment tools. Teachers suggested integrating reading-centric activities, encouraging extended reading practices outside the classroom, using flashcards and mnemonic devices, incorporating collaborative group activities, employing multimedia strategies, improving student motivation, increasing group competitions, offering workshops, strengthening personalized feedback, introducing frequent vocabulary quizzes and journals, and assisting students in setting personal vocabulary goals.
