This research focuses on developing English Language Teaching (ELT) materials for seventh-grade students, particularly for Chapter 3 "Home Sweet Home" in Unit 1 "My House" at MTsN Gowa. The materials are designed according to the Merdeka curriculum and are enhanced by the Mastery Learning model. The researcher employed the Research and Development (R&D) technique and the ADDIE model as an instructional design framework. In order to assess the needs of the students in class VII MTsN Gowa, the researcher distributed questionnaires to the students in order to determine the goals and learning requirements of the class. An Alur Tujuan Pembelajaran (ATP) comprising learning objectives, content, time allocation, Pancasila student profiles, needs analysis, and learning activities based on the mastery learning paradigm was established by the researcher during the design stage. The phases of mastery learning, orientation, presentation, structured training, guided practice, and self-practice were followed in the creation of ELT materials. The results of the needs analysis show that students can generally describe and categorize objects and characteristics of objects in the house, but have difficulty in identifying the position of objects. The designed materials effectively addressed this gap, improving students' understanding and ability. The development phase involved creating ELT materials tailored to the stages of mastery learning, which were then tested and refined through iterative feedback and revision. The validation results showed a high level of validity with a score of 3.83, classifying the materials as highly valid. This research can be one of the main references in R&D research.
