A good understanding of school mathematics knowledge, particularly ratio topics, is urgent for pre-service mathematics teachers. This is important considering that in supporting their professional duties as educators. However, many pre-service mathematics teachers still face learning obstacles when studying this material. This study aims to develop a didactic design for teaching ratio topics in school mathematics by analyzing scholarly knowledge and praxeological organization to help minimize these learning obstacles. The research employed a qualitative method with a hermeneutic phenomenology approach. Data analysis adhered to the three stages of Didactical Design Research (DDR): prospective, metapedadidactic, and retrospective stage. The research identified learning obstacles among 25 participants who had completed proportion topics in Junior High School Mathematics course, while 20 participants who were currently enrolled in the course took part in the implementation of the hypothetical design. The findings of this study indicate: (1) The characteristics of learning obstacles for pre-service teachers are didactical obstacles in the arrangement of ratio materials, ontogenic obstacles in basic technical arithmetic, and epistemological obstacles in knowledge of the concepts of ratio and proportion; (2) The development of a hypothetical learning trajectory for ratio topics; (3) The design of a hypothetical didactic model for teaching ratio topics based on the Theory of Didactical Situations (TDS) encompassing four situations: action, formulation, validation, and institutionalization; (4) The implementation results of the hypothetical didactic design indicated student responses aligned with the previously designed didactic pedagogical anticipation framework; (5) The analysis of the research results produced a recommended didactic design for teaching ratio topics. Overall, this study underscores the importance of a didactic design for ratio topics in school mathematics to support the development of professional competencies in pre-service teachers, thereby preparing them to teach this topic more effectively. Identifying the characteristics of learning obstacles after the implementation of didactic design is one of the recommended follow-ups of this study
