The aim of this study is to evaluate the "Traveller" textbook series from teachers' perspectives. Areas of evaluation are the textbooks' activities, skills, and appropriateness. The study implemented a mixed-methods approach using two instruments: content analysis, and questionnaire. The data collection of the content is carried out by analyzing the content of the six textbooks, from "Traveller 1" to "Traveller 6"; the questionnaire themes were used for the content analysis. 94 teachers responded the questionnaire. The results show that textbook is effective according to the layout, accessibility, activities and skills but teachers hold mixed perspectives regarding its appropriateness. Moreover, results revealed that there might be an association between the teachers' attitudes and the teachers' training and class size.
