A systematic review of interventions for children presenting with dyscalculia in primary schools

A theory of degrees in education

Degrees are presumably the most important institution in education markets. However, despite their high relevance, degrees and their design features remain poorly understood within the economics of education. This study addresses this gap. We provide an accurate formal definition of what constitutes a degree and formulate the first theory of degree design. This theory is based on a technological platform view that interprets degrees as modules within a hierarchical structure resembling that of software architectures. This approach provides new opportunities to address questions of degree optimization. Furthermore, a novel strategy to optimize the design of school degrees is proposed. This strategy is expected to improve the learning environment of weaker students across all school types, leaving higher-performing students rather unaffected. The implications and limitations of our approach are also discussed.

Efficacy of Learning Disorder Treatment for Reading or Mathematics Disorders: An Open Study

Objectives

This study aimed to identify the effectiveness of treatment programs for children with reading (RD) or mathematics disorders (MD). Structured treatment programs were developed to improve phonological awareness and number sense among children and adolescents with RD or MD, respectively, and the effectiveness of the learning disorder treatment programs were evaluated.

Methods

We used standardized, objective diagnostic, and evaluation tools not only to recruit participants with RD, MD, or comorbid attention deficit and hyperactivity disorder, but also to assess the effectiveness of the treatments regarding both improved core neurocognitive deficits of RD or MD and academic achievement. Forty children with RD or MD received one-on-one treatments from therapists.

Results

In the RD group, treatment effects were observed in all subtests. In the word and paragraph reading tests, the accuracy rates and fluency improved. The results of the phonological working memory test, word-sound correspondence test, and rapid automatic naming tests also improved. In the MD group, the accuracy rate and fluency on the arithmetic test improved. An increase in the accuracy rate in the size and distance comparison tests and a decrease in the error rate in the estimation test were also observed. However, there were no improvements in reaction time in these subtests.

Conclusion

Learning disorder treatment programs that focus on improving phonological awareness or number sense in children with RD or MD improved achievement, phonological awareness, and number sense.

Cognition and learning difficulties in a representative sample of school-aged children with cerebral palsy

BACKGROUND

Nearly half of all children with CP experience intellectual impairment, with impacts on academic achievement.

AIMS

To assess cognitive and academic functioning for primary-school aged children with CP METHODS AND PROCEDURES: This population-based cohort study assessed 93 participants (male n = 62; mean = 9 years 9 months, SD 1 y 1.8 months) on measures of fluid and crystallised intelligence (Raven's Coloured Progressive Matrices, Peabody Picture Vocabulary Test) and academic achievement (Wechsler Individual Achievement Test). Analyses included t-tests, Pearson's chi-square and regression.

OUTCOMES AND RESULTS

41 (44.1%) children met criteria consistent with intellectual developmental disorder. Academic skills were significantly below population means on word reading (M= 85.4, SD = 19.3), t(66) = -6.2, p < .001; spelling (M=83.3, SD=19.7) t(65) = -6.87, p < .001; and numerical operations (M=72.9, SD=21.7) Z = 66.0, p < .001. Cognitive ability was associated with GMFCS level (χ² (1, N = 93) = 16.15, p < .001) and diagnosis of epilepsy (χ² (2, N = 93) = 11.51 p = .003). Crystallised and fluid intelligence together accounted for 65% of the variance in word reading, 56% in spelling and 52% in numerical operations.

IMPLICATIONS

Many children with CP experience academic challenges. Screening is recommended for all children with CP and full psychoeducational assessment undertaken when children with CP experience academic difficulties.

Persistent Effects of Musical Training on Mathematical Skills of Children With Developmental Dyscalculia

Musical training (MT) is perceived as a multi-sensory program that simultaneously integrates visual, aural, oral, and kinesthetic senses. Furthermore, MT stimulates cognitive functions in a ludic way instead of tapping straight into the traditional context of school learning, including mathematics. Nevertheless, the efficacy of MT over mathematics remains understudied, especially concerning longstanding effects. For this reason, this longitudinal study explored the impact of MT on numerical cognition and abstract visual reasoning using a double-blind and quasi-experimental design. We assessed two groups of children from primary schools, namely one with developmental dyscalculia [DD; n = 22] and another comprising typically developing children [TD; n = 22], who concomitantly underwent MT. Numerical cognition measurement was carried out at four different time points: Baseline (pre-MT assessment), mid-test (after 7 weeks of MT), post-test (after 14 weeks of MT), and follow-up (10 weeks after the end of MT). Significant interactions were found between time and group for numerical cognition performance, in which the DD group showed higher scores in number comprehension, number production at mid-test, and calculation at post-test compared to baseline. A key finding was that number production, number comprehension, and calculation effects were time-resistant for the DD group since changes remained on follow-up. Moreover, no significant differences over time were found for abstract visual reasoning for both groups. In conclusion, the findings of this study showed that MT appears to be a useful tool for compensatory remediation of DD.
