EXPLORATORY CONTENT ANALYSIS IN INDONESIAN SENIOR HIGH SCHOOL ENGLISH TEXTBOOK

This study aimed to evaluate the suitability of the textbook “Buku Interaktif Active English” for 10th-grade students based on the Merdeka curriculum. The method used is a mixed method, with data collection through Cunningsworth’s TeachersStudents Textbook Review (Checklist) in eight aspects, as well as observation to explore the views and experiences of textbook users in the learning process. Data
was analyzed quantitatively for textbook review data using a Guttman Scale and qualitatively using Krippendorff's Content Analysis, with results compiled in a Qualitative Descriptive. The results showed that while the textbook has some strengths, such as alignment with the learning objectives, there are also significant weaknesses, including a lack of a teacher’s guidebook and overly theoretical
material. In addition, the textbook lacks support for the project-based learning approach expected in the Merdeka curriculum. The conclusion of this study recommended improvements to the textbook, including providing a teacher’s guidebook and improving the quality of materials to make it more relevant to the students’ needs. Further research is also recommended to explore the long-term
impact of using this textbook in English language learning in Indonesia.
