Effectiveness of Interventions for School Children With Developmental Dyscalculia

Posted on by

Abstract

This review aimed to evaluate the effectiveness of interventions for children with developmental dyscalculia (DD). The PsycINFO, ERIC, PubMed, Scopus, Science direct, Google scholar, and Google databases and search engines were searched. Studies employed experimental and quasiexperimental designs were reviewed. Thirty three studies with 1792 children aged 6-12 years were chosen. A large pooled effect size was found (Hedge’s g = .93; 95% CI [.38, 3.09]). There was no statistically significant moderator variable predicting the pooled effect size. Finally, publication bias was found, as shown by Egger’s regression test analysis. Overall, interventions have generally large effect in improving the numerical skills of children with DD.

How can colleges support students with Dyscalculia?

Posted on by

Dyscalculia affects an estimated 4% to 7% of students, yet it remains significantly less recognized than other learning difficulties like dyslexia. This lack of awareness often leads many students to navigate higher education without formal support. Here, we explore how colleges can implement proactive strategies to support students with dyscalculia, particularly within STEM subjects.

Direct effects of dyscalculia on executive functions

Posted on by

Dyscalculia, a specific learning disability in mathematics, is linked to deficits in executive functions, yet integrative studies in Arabic-speaking contexts remain scarce. This study examined working memory, inhibition, and cognitive flexibility collectively in children with dyscalculia. Using 64 children (32 per group), advanced techniques including Ridge regression, PCA, and ROC analysis assessed these functions. Both groups demonstrated average intelligence (Raven’s Progressive Matrices), with the dyscalculia group showing profound mathematical deficits across nine arithmetic domains.
