Calcularis – evaluation of a computer based learning program for enhancing numerical cognition for children with developmental dyscalculia

by Aster M., et al, 2015, AACAP

The goal of this study was to determine whether Calcularis was also capable of helping younger students improve the numeracy skills in which they showed the greatest need for support. In addition, the study investigated whether the children’s anxiety about maths could be reduced by the training. The children, who were aged from 7 to 10 years, practised over a 6-week period: a relatively short time in comparison to other studies on the software. They completed five training sessions of 20 minutes instead of three to four sessions of 15-20 minutes.


The study showed that the children with dyscalculia or weakness in numeracy were able to measurably improve their skills in numerical processing, addition and, in particular, subtraction. The study also established a significant reduction in maths anxiety.
