Doabler, Christian T.; Nelson, Nancy J.; Kennedy, Patrick C.; Stoolmiller, Mike; Fien, Hank; Clarke, Ben; Gearin, Brian; Smolkowski, Keith; Baker, Scott K. – Learning Disability Quarterly, 2018
Accumulating research has established explicit mathematics instruction as an evidence-based teaching practice. This study utilized observation data from a multi-year efficacy trial to examine the longitudinal effects of a core kindergarten mathematics program on the use of explicit mathematics instruction among two distinct groups of teachers: one…

Strand Cary, Mari G.; Clarke, Ben; Doabler, Christian T.; Smolkowski, Keith; Fien, Hank; Baker, Scott K. – Learning Disability Quarterly, 2017
We report on a practitioner implementation of Fusion, a first-grade mathematics intervention. Studies such as this evaluation of a loose implementation under realistic conditions are important to curriculum developers' understanding of how evidence-based programs and tools work under a variety of implementation scenarios. In this…

Powell, Sarah R.; Driver, Melissa K. – Learning Disability Quarterly, 2015
Researchers and practitioners indicate students require explicit instruction on mathematics vocabulary terms, yet no study has examined the effects of an embedded vocabulary component within mathematics tutoring for early elementary students. First-grade students with mathematics difficulty (MD; n = 98) were randomly assigned to addition tutoring…

Swanson, H. Lee; Moran, Amber; Lussier, Cathy; Fung, Wenson – Learning Disability Quarterly, 2014
The purpose of this study was to investigate the effectiveness of explicit, direct, and generative strategy training and working memory capacity (WMC) on mathematical word problem-solving accuracy in elementary schoolchildren. In this study, children in third grade ("N" = 82) identified as at risk for math difficulties (MD) were randomly…

Solis, Michael; Miciak, Jeremy; Vaughn, Sharon; Fletcher, Jack M. – Learning Disability Quarterly, 2014
We describe findings from a series of longitudinal studies utilizing a response to intervention framework implemented over 3 years with students in Grades 6 through 8 with reading disabilities and poor reading comprehension. Students were identified based on reading comprehension scores in Grade 5 (n = 1,083) and then randomized to treatment or…

Leh, Jayne M.; Jitendra, Asha K. – Learning Disability Quarterly, 2013
This study compared the effectiveness of computer-mediated instruction (CMI) and teacher-mediated instruction (TMI) on the word problem-solving performance of students struggling in mathematics. Both conditions integrated cognitive modeling that focused on the problem structure using visual representations with critical instructional elements…
