Extensive Reading (ER) has gained increasing attention as a valuable language learning activity in Vietnam. However, the implementation of ER programs in the classroom may face various challenges, such as a lack of understanding among teachers about the difference between Intensive Reading and Extensive Reading, and the difficulties in setting up and funding an ER program. This poster session will report on a replication study of Waring and Chu's (2017) research on attitudes and beliefs towards ER in Vietnam, focusing specifically on the views of teachers from a range of educational backgrounds. The study aims to investigate the current attitudes and beliefs of teachers towards ER, the challenges they face in implementing ER programs, and highlight any changes in these factors over the previous five years. The presentation will discuss the research design and the results, and the implications for promoting ER in Vietnamese language education.
