The Effect of efficiency of cooperative learning method on increasing blind students' perception of mathematical conceptions

Blind students have limitations that their teachers have to apply efficient educational methods for them. Since mathematics concepts are abstract for blind students and they cannot understand these concepts deeply, this research has tried that used and introduced cooperative learning method for this reason. Blind students have high listening capacity then cooperative learning method can promote other their capacities. Through quasi-experimental method, 40 girl blind students are chosen at third grade of elementary level. Basic mathematical operations are taught via cited method. The results of T-tests indicated that cooperative learning can be positive effect on solving capacity of blind students for basic mathematical concepts.
