Effective Programs in Elementary Mathematics

Posted on by

This article reviews research on the achievement outcomes of elementary mathematics programs. 87 rigorous experimental studies evaluated 66 programs in grades K-5. Programs were organized in 6 categories. Particularly positive outcomes were found for tutoring programs (ES=+0.20, k=22). Positive outcomes were also seen in studies focused on professional development for classroom organization and management (e.g., cooperative
learning) (ES=+0.19, k=7). Professional development approaches focused on helping teachers gain in understanding of mathematics content and pedagogy had little impact on student achievement. Professional development intended to help in the adoption of new curricula had a small but significant impact for traditional (non-digital) curricula (ES=+0.12, k=7), but not
for digital curricula. Traditional and digital curricula with limited professional development, as well as benchmark assessment programs, found few positive effects.

Educational Robotics and Game-Based Interventions for Overcoming Dyscalculia: A Pilot Study

Posted on by

Recent studies suggest that educational robotics and game-based learning can provide engaging and adaptive learning environments, enhancing numerical cognition and motivation in students with mathematical difficulties. The intervention was designed to improve calculation skills, problem-solving strategies, and overall engagement in mathematics. The study involved 73 secondary students, divided into three classes, among whom only a specific group had been diagnosed with dyscalculia. Data were collected through pre- and post-intervention assessment evaluating improvements in numerical accuracy, processing speed, and support motivation. Preliminary findings indicate that robotics and gamification create an interactive, less anxiety-inducing learning experience, facilitating conceptual understanding and retention of mathematical concepts. The results suggest that these tools hold promise as supplementary interventions for children with dyscalculia. Future research should explore long-term effects, optimal implementation strategies, and their integration within formal educational settings.

Theoretical models of developmental dyscalculia

Posted on by

In recent decades, various theoretical models have been proposed to explain the origins of developmental dyscalculia (DD). In this chapter, we review domain-general and domain-specific deficit theories of DD. When considering domain-general deficits, it has been observed that verbal working memory (WM) consistently predicts differences between children with DD and typically developing children in diverse age groups and samples, even after accounting for demographic and other cognitive variables.

Memory Abilities in Children With Subtypes of Dyscalculia

Posted on by

This study examines (a) mathematical skills of 2 subgroups of children with developmental dyscalculia (DD)-1 group with DD only and a second group with DD plus reading disorders (RDD)-and (b) analyzes the memory skills of both groups of children. Fifty 11- and 12-year-old children were selected from public schools in Guadalajara, Mexico. Seventeen children had DD only, 13 had RDD, and 20 were normal controls. Testing included 10 calculation and 6 memory subtests taken from the Evaluacion Neuropsicologica Infantil (Matute, Rosselli, Ardila, & Ostrosky, in press). Results indicated that children with DD and children with RDD show a similar pattern of mathematical impairment. Both subgroups had significantly lower scores than the control group in working memory tasks. In addition, the RDD group had significantly lower scores than the control group in visual learning and semantic memory. Although the RDD group scored lower than the DD group in most memory tests, this difference did not reach significance. Working memory tests (digits backwards and sentence repetition) appeared to be the best predictors of mathematical test scores and may represent a major cognitive defect in children with specific defects in mathematics.
