Each student has different characteristics when learning mathematics. There are students who are very easy to learn, while others have difficulty learning mathematics (dyscalculia). In order for the learning objectives to be implemented, good teaching materials are needed that are tailored to the needs of students so that learning outcomes can be fulfilled optimally. The purpose of this study was to determine the results of the validation of the development of a mathematical module based on character education containing the local culture of "Gusjigang"for dyscalculia students that had been developed. Validation results from experts are needed in module development. This is because the module is feasible or not to be used. The research data was obtained from the questionnaire analysis of the validity of seven validators with expertise in mathematics learning media, linguistic content and mathematical material. The module validation analysis uses the Crocker and Algina methods. After the analysis, it is known that the average feasibility aspect for mathematics content is 89.11% with very good criteria, for linguistic content is 85.86% with very good criteria, and for mathematics learning media content is 87.25% with very good criteria also. Therefore, the mathematics module based on character education containing the local culture of "Gusjigang"for dyscalculia students meets the feasibility aspect. In conclusion, the developed module is suitable for use in terms of mathematics materials, language, and mathematics learning media for dyscalculia students. © 2023 Author(s).
