The data were analyzed using triangulation consisting of data reduction, presentation, and conclusion and verification. techniques consisted of curriculum and mathematics teaching materials. The data collected through interview and documentation. The subject consisted of two mathematics teachers.
The research was conducted in one of the Private Madrasah Ibtidaiyah in South Tangerang, Indonesia.
Qualitative research was used in this research. This research aimed to describe the need to analyze mathematics teaching materials based on mathematical proficiency in Madrasah Ibtidaiyah. The results of this study contribute to providing alternative teaching materials for deaf students. Finally, the effective criterion is that the average score of students trying to solve the test questions is 81. Furthermore, the practical standard is because the percentage of the average response score of students obtained is 80%. Valid because the average value of the three validators is 3.85. Teaching materials that have been developed and tested on deaf class VIII students are suitable for use as a learning medium because they meet the criteria of being valid, practical, and effective. The development model used is a modified development model from the 4D model. Therefore, this study aims to develop visual-based mathematics teaching materials on integer arithmetic operations, one of which is deaf. It is because some researchers always focus on standard students. However, several learning tools for them are still very few. Students who have special needs also have the right to obtain an education as a provision for life, just like regular students.
