摘要

The learning process for the visually impaired students (VIS) is complicated because they are unable to get visual information. A lot of challenges and problems these VIS are facing to get education, especially in studying Mathematics. As a developing country, Bangladesh cannot afford for the costly Mathematics learning tools for VIS. The objective of this study is to analyze the current scenarios of learning Mathematics in different types of blind schools in Bangladesh. A survey is conducted in all three types of schools in order to achieve the objective. The survey was based on questionnaire comprising questions related to Mathematics learning, examination methods and learning difficulties. Survey results shows that they follow Braille system for reading and writing; however, they cannot write in Braille in the final examination. Taylor frame and abacus are the only options for counting numbers. This paper also tries to propose some key points to improve the current Mathematics learning process for the blind students.
