In this study, validation is needed to validate the product. Validation was conducted by two experts, where the results of the ATP validation were 91,7 (very good) and the Module validation results were 3.7 (very valid). the experts suggest that the ATP and Module align well with students' requirements and other key factors. This implies that the ATP and Module are valid and can serve as a practical alternative learning resource for students. This research offers valuable insights for fellow researcher in the literature field. The creation of English language materials in this study has the potential to boost students' motivation for learning, tailored to their specific requirements.
