The Utility of a Computer-assisted Instructional Software(Hesabyar) for Teaching Mathematics to Students with Dyscalculia

To study the effect of computer–assisted instructional software on counting, addition and subtraction learning for students with learning disability. 20 students with dyscalculia (7-8 years old) were randomly selected and matched into a quasi-experimental control group design. The results of Iranian version of Key Math test (Mohammad Esmaeel and Hooman, 2002) scores of the two groups by t-test showed that: application of the designed instructional software has a significant effect on counting, addition and subtraction learning for students with dyscalculia. This software can be considered as an appropriate means for teaching arithmetic operations to these students.
