EFL teachers’ beliefs and practices in teaching vocabulary to 10th and 11th graders at Phan Chau Trinh high school, Danang city

Vocabulary is an important aspect of language learning. This research aims to explore English language teachers’ beliefs and practices in vocabulary teaching at Phan Chau Trinh High School, Danang. Through the qualitative data collected via questionnaire, interview and classroom observation, the findings indicated that teachers’ beliefs influence their classroom practices during vocabulary teaching. The study also reveals a positive correlation between teachers’ own interest and the effectiveness of their vocabulary teaching practices. Despite certain beliefs held by the teachers, different limitations arose, hindering the seamless vocabulary instruction. This shows that maintaining a constant alignment between what teachers believe and what they do in practical contexts is not always possible.
