The English language textbook for classes XI-XII, currently in use nationwide in Bangladesh, has drawn numerous reactions from multiple corners of the country. Bangladeshi teachers, major stakeholders, have been noticeably concerned about the effectiveness of the design of the textbook based on their teaching experiences (Hani & Siddika, 2018). It is important to know their perceptions of the textbook, since their perceptions have a significant influence on students’ learning English through the textbook. The current study, therefore, seeks to provide information about the participant teachers and their teaching contexts in order to judge the value of the textbook design in terms of contents selection and organization. For that research purpose, interviews were conducted with 10 teachers who were, at the time of research, teaching the textbook at different colleges in a district of the country. Based on the data, the study discusses the teachers’ first-hand experience with the textbook, providing a revealing insight into how well it facilitates students’ learning in the classroom. Finally, implications are suggested that are expected to guide the design of the next applicable version of the textbook.
