Clarke, Ben; Turtura, Jessica; Lesner, Taylor; Cook, Madison; Smolkowski, Keith; Kosty, Derek; Doabler, Christian T. – Exceptional Children, 2022
We replicated a study of a kindergarten mathematics intervention, ROOTS, delivered in the context of a research-based core program. We randomly assigned 62 classrooms to treatment (ROOTS) or a business-as-usual control. All classrooms implemented the research-based core program (Early Learning in Mathematics). Participants included 163 treatment…

Doabler, Christian T.; Clarke, Ben; Kosty, Derek; Maddox, Steven A.; Smolkowski, Keith; Fien, Hank; Baker, Scott K.; Kimmel, Georgia L. – Journal of Learning Disabilities, 2021
A concerning number of students enter kindergarten facing an intractable variation of mathematics difficulties (MD). This study investigated the impact of an explicit, core kindergarten mathematics program on the mathematical outcomes of kindergartners who demonstrated risk for severe MD at kindergarten entry and examined whether these students…

Doabler, Christian T.; Clarke, Ben; Kosty, Derek; Turtura, Jessica E.; Firestone, Allison R.; Smolkowski, Keith; Jungjohann, Kathleen; Brafford, Tasia L.; Nelson, Nancy J.; Sutherland, Marah; Fien, Hank; Maddox, Steven A. – Exceptional Children, 2019
Well-designed mathematics instruction focused on concepts and problem-solving skills associated with measurement and data analysis can build a foundational understanding for more advanced mathematics. This study investigated the efficacy of the Precision Mathematics Level 1 (PM-L1) intervention, a Tier 2 print- and technology-based mathematics…

Doabler, Christian T.; Clarke, Ben; Kosty, Derek; Turtura, Jessica E.; Sutherland, Marah; Maddox, Steven A.; Smolkowski, Keith – Journal of Learning Disabilities, 2021
Implementation of evidence-based practices (EBPs) is paramount to students' development of mathematics proficiency. This study investigated "practice-based evidence" of interventionists' actual use of explicit mathematics instruction, a well-established EBP. Specifically, this study analyzed direct observation data collected in a…

Doabler, Christian T.; Clarke, Ben; Kosty, Derek; Fien, Hank; Smolkowski, Keith; Liu, Meijia; Baker, Scott K. – Learning Disability Quarterly, 2021
Instructional interactions that occur between teachers and students around foundational mathematics topics are critical for supporting mathematical proficiency among students with mathematics learning disabilities (MLD). This study investigated whether the initial mathematics skill of 880 kindergarten students at risk of MLD predicted the quantity…

Garbacz, S. Andrew; Stormshak, Elizabeth A.; McIntyre, Laura Lee; Kosty, Derek – School Psychology, 2019
The impact of the Family Check-Up (FCU) on family-school engagement was tested in a randomized, controlled trial. Participants were primary caregivers of 321 children. Approximately 87% of families randomly assigned to the intervention agreed to participate and received the intervention. Caregivers in the FCU condition outperformed caregivers in…
