Özet:

The deaf-mute students have limited communication and knowledge, which result in their limitations in learning mathematics. This study aims to determine the development of the deaf-mute student in learning mathematics, especially about a fraction. The method used is the Single Subject Research (SSR) by implementing the Indonesia Realistic Mathematics Education (IRME) Approach by using the context of pipettes. Data collection techniques used are video recordings, documentation, and written data. This research instrument uses videos to see the learning process and when students work on the given problems, photos to refer the results of student work, and written test in worksheets to get the data on student’s work. The data analysis technique used is analyzed in conditions and between conditions with A-B research design. The research results show that the implementation of IRME approach using the pipette context can improve the understanding of fraction concepts and the learning outcomes of the deaf-mute student. All intervention and student’s strategy in learning process would be described in this paper.
