Use of cognitive correction training improves learning for children with mathematics learning disability

Children with normal intelligence may experience varying degrees of mathematics learning disabilities (MD). This study aims to conduct training to improve the brain's cognitive ability for mathematics learning by focusing on two important mathematical cognitive abilities. This was a prospective study of 70 children in grades 2-5 from two primary schools in Changzhou and with MD enrolled from June 2015 to February 2017. The children were randomized 1:1 to the training and control groups. A training cycle included 40 sessions (5/weeks) (30 min each session). The efficacy of learning was assessed by assessing number learning and graph reasoning, and by using the Raven standard reasoning test score. In the training group, backward number memory (from 6.1 ± 1.8 to 6.7 ± 1.3, P = 0.02), number sequential connection (from 54.4 ± 14.5 to 47.1 ± 12.1, P < 0.01), and rapid graph judgment (from 531.9 ± 76.3 to 557.8 ± 85.7, P = 0.04) were improved by training, while there was no effect on forward number memory (P = 0.13). There were significant differences in total score and scores of b, c, and e series before and after training (all P < 0.05). The children in the control group had no improvement after 8 weeks. There was a correlation between the ability of rapid graphic judgment before and after training and the score of the Raven E series (r = 0.384, P = 0.024), and between the score of the Raven C series and the score of the Raven D series (r = 0.468, P = 0.013). Cognitive correction training improved the sensitivity to numbers and mathematics learning in children with MD.
