Subclaims¶

q3 i? A significant treatment x WMC interaction emerged on CMAT solution accuracy, F(3,140)=4.25, p < .01. → Swanson et al. 2013

Evidence¶

Swanson et al. 2013¶

H. Lee Swanson, Michael J. Orosco, Cathy Lussier. (2013). Does Cognitive Strategy Training on Word Problems Compensate for Working Memory Capacity in Children with Math Difficulties? SREE Spring 2013 Conference. https://eric.ed.gov/?id=ED563039

q3 · i? · causal · r2

Mixed model ANCOVA of the randomized 2 (MD vs. NMD) x 4 (treatment) design on posttest CMAT solution accuracy, with pretest accuracy and WMC as covariates. The article reports "A significant effect emerged for the treatment x WMC interaction"; the risk x treatment x WMC interaction only approached significance, p < .10.

"A significant effect emerged for the treatment x WMC interaction, F (3,140) =4.25, p < .01 and the pretest CMAT score, F (1,140) =76.70, p < .001."

Discussion¶

Learner Variables¶

• Working Memory — moderator: an instructional effect differs with it

Related Claims¶

• At high pretest WMC, the visual-only condition outperformed verbal-only, verbal+visual, and control on solution accuracy — related
• At low pretest WMC, control children outperformed the strategy conditions on solution accuracy — a narrower finding that bears on this claim
• The treatment x WMC interaction persists after controlling reading, calculation, and fluid intelligence — a narrower finding that bears on this claim
• Verbal and verbal+visual strategy conditions improve calculation accuracy for both ability groups — reports the opposite
• Combined verbal+visual strategy instruction improves standardized problem-solving accuracy for children with math difficulties — related
• Working memory capacity correlates with outcomes differently across strategy conditions, with compensatory negative correlations under materials-only instruction — related
