q3 i? Children with MD showed substantial drops in performance from Wave 2 to Wave 3, whereas children without MD showed steady increases across testing waves. → Swanson 2013

Evidence¶

Swanson 2013¶

Swanson, H. L., Lussier, C. M., & Orosco, M. J. (2013). Cognitive Strategies, Working Memory, and Growth in Word Problem Solving in Children With Math Difficulties. Journal of Learning Disabilities, 48(4), 339–358. doi:10.1177/0022219413498771

q3 · i? · causal · r2

Figures 2 and 3 (Panels a and b) intent-to-treat growth analysis; the article describes "substantial drops in performance from Wave 2 to Wave 3" for children with MD, with a roughly 3-month summer break between waves.

"There were substantial drops in performance from Wave 2 to Wave 3 in accuracy scores as a function of treatment conditions. In contrast, as shown in Panel b, children without MD showed steady increases in performance across the testing waves."
