Furthermore, Thein (2006) conducted a study to evaluate the suitability and effectiveness of the textbooks used for teaching English to religious studies students at Myanmar Institute of Technology. Questionnaires, interviews, and classroom observations were used to collect data both from teachers and learners. The study was aimed at investigating the extent to which teachers and learners’ expectations match the objectives of the program in developing students' communicative skills and critical thinking. The findings revealed that textbooks used in the program were not suitable for reasons including: the textbooks did not contribute to achieve the needs and wants of both teachers and learners, they were not effective to promote students' critical thinking, and they were not effective in improving the students' communicative skills for everyday life situations. Thein (2006) suggested that textbooks must be localized to meet teachers and learners' needs. He also emphasized upon the importance of adapting activities that encourage collaborative learning, natural and experiential interactions to help young people think critically.
