Fuchs, Lynn S.; Malone, Amelia S.; Schumacher, Robin F.; Namkung, Jessica; Hamlett, Carol L.; Jordan, Nancy C.; Siegler, Robert S.; Gersten, Russell; Changas, Paul – Journal of Educational Psychology, 2016
The main purposes of this study were to test the effects of teaching at-risk 4th graders to provide explanations for their mathematics work and examine whether those effects occur by compensating for limitations in cognitive processes. We randomly assigned 212 children to 3 conditions: a control group and 2 variants of a multicomponent fraction…

Does Working Memory Moderate the Effects of Fraction Intervention? An Aptitude-Treatment Interaction
Fuchs, Lynn S.; Schumacher, Robin F.; Sterba, Sonya K.; Long, Jessica; Namkung, Jessica; Malone, Amelia; Hamlett, Carol L.; Jordan, Nancy C.; Gersten, Russell; Siegler, Robert S.; Changas, Paul – Journal of Educational Psychology, 2014
This study investigated whether individual differences in working memory (WM) moderate effects of 2 variations of intervention designed to improve at-risk 4th graders' fraction knowledge. We also examined the effects of each intervention condition against a business-as-usual control group and assessed whether children's measurement interpretation…
