Clarke, Ben; Doabler, Christian T.; Turtura, Jessica; Smolkowski, Keith; Kosty, Derek B.; Sutherland, Marah; Kurtz-Nelson, Evangeline; Fien, Hank; Baker, Scott K. – Elementary School Journal, 2020
This study examined whether the efficacy of ROOTS, a 50-lesson mathematics intervention program focused on whole number concepts for at-risk kindergarten students, differed by group size and whether initial skill moderated intervention effects by group size. The study utilized a randomized block design with at-risk students (n = 1,251) within…

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; Kurtz-Nelson, Evangeline; Fien, Hank; Smolkowski, Keith; Baker, Scott K. – Journal of Learning Disabilities, 2019
Group size and treatment intensity are understudied topics in mathematics intervention research. This study examined whether the treatment intensity and overall intervention effects of an empirically validated Tier 2 mathematics intervention varied between intervention groups with 2:1 and 5:1 student-teacher ratios. Student practice opportunities…

Clarke, Ben; Doabler, Christian T.; Kosty, Derek; Kurtz Nelson, Evangeline; Smolkowski, Keith; Fien, Hank; Turtura, Jessica – AERA Open, 2017
This study used a randomized controlled trial design to investigate the ROOTS curriculum, a 50-lesson kindergarten mathematics intervention. Ten ROOTS-eligible students per classroom (n = 60) were randomly assigned to one of three conditions: a ROOTS five-student group, a ROOTS two-student group, and a no-treatment control group. Two primary…

Doabler, Christian T.; Stoolmiller, Mike; Kennedy, Patrick C.; Nelson, Nancy J.; Clarke, Ben; Gearin, Brian; Fien, Hank; Smolkowski, Keith; Baker, Scott K. – Assessment for Effective Intervention, 2019
A growing body of research suggests that the effects of core mathematics instruction on student mathematics outcomes may not be uniform across different skill levels in mathematics. This study investigated the extent to which observed components of explicit mathematics instruction explained why students' initial mathematics achievement was…

Low, Sabina; Smolkowski, Keith; Cook, Clayton; Desfosses, Danielle – Developmental Psychology, 2019
This study examined the impact of a commonly adopted elementary universal social-emotional learning program, Second Step, on student social-emotional and academic outcomes following 2 years of implementation. The cluster-randomized wait-list control trial included 61 schools, 321 teachers, and 8,941 early elementary students across 2 states, with…

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.

Clarke, Ben; Doabler, Christian T.; Strand Cary, Mari; Kosty, Derek; Baker, Scott; Fien, Hank; Smolkowski, Keith – School Psychology Review, 2014
This pilot study examined the efficacy of a Tier 2 first-grade mathematics intervention program targeting whole-number understanding for students at risk in mathematics. The study used a randomized block design. Students (N = 89) were randomly assigned to treatment (Fusion) or control (standard district practice) conditions. Measures of…
