Clarke, Ben; Doabler, Christian T.; Smolkowski, Keith; Turtura, Jessica; Kosty, Derek; Kurtz-Nelson, Evangeline; Fien, Hank; Baker, Scott K. – Exceptional Children, 2019
This study examined the role of initial skill in moderating intervention effects of a 50-lesson mathematics intervention program, ROOTS, for at-risk kindergarten students focused on developing whole-number concepts and skills. The study utilized a randomized block design with at-risk students (n = 592) within classrooms (n = 60) randomly assigned…

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…

Shanley, Lina; Clarke, Ben; Doabler, Christian T.; Kurtz-Nelson, Evangeline; Fien, Hank – Journal of Special Education, 2017
Early number skills, comprised of both informal and formal skills, are associated with later mathematics achievement. Thus, the development of foundational early number skills is an important aspect of early mathematics instruction. This study explored relations between early number skills gains and mathematics achievement for students at risk for…

Doabler, Christian T.; Clarke, Ben; Kosty, Derek B.; Kurtz-Nelson, Evageline; Fien, Hank; Smolkowski, Keith; Baker, Scott K. – Exceptional Children, 2016
The purpose of this closely aligned conceptual replication study was to investigate the efficacy of a Tier 2 kindergarten mathematics intervention. The replication study differed from the initial randomized controlled trial on three important elements: geographical region, timing of the intervention, and instructional context of the…

Clarke, Ben; Baker, Scott; Smolkowski, Keith; Doabler, Christian; Strand Cary, Mari; Fien, Hank – Journal of Research on Educational Effectiveness, 2015
This study examined the efficacy of a core kindergarten mathematics program, Early Learning in Mathematics (ELM), a 120-lesson program with four content strands: (a) number operations, (b) geometry, (c) measurement, and (d) vocabulary. The study utilized a randomized block design, with 129 classrooms randomly assigned within schools to treatment…

Clarke, Ben; Strand Cary, Mari G.; Shanley, Lina; Sutherland, Marah – Grantee Submission, 2018
This manuscript presents the results from a study to investigate the technical characteristics of two versions of a number line assessment (NLA 0-20 and NLA 0-100). The sample consisted of 60 kindergarten and 46 first grade students. Both number line versions had sufficient alternate form and test-retest reliability. The NLA 0-20 had low and the…

Nelson-Walker, Nancy J.; Doabler, Christian T.; Fien, Hank; Gause, Marshall; Baker, Scott K.; Clarke, Ben – Society for Research on Educational Effectiveness, 2013
Widespread concern has been expressed about the persistent low mathematics achievement of students in the US, particularly for students from low-income and minority backgrounds and students with disabilities. Instructional gaming technology, when designed and fictionalized well, has the potential to improve the motivation and mathematics…

Chard, David J.; Clarke, Ben; Baker, Scott; Otterstedt, Janet; Braun, Drew; Katz, Rachell – Assessment for Effective Intervention, 2005
As recent research efforts have focused on preventing reading difficulties and enhancing the effectiveness of special education services for students with reading problems, similar efforts in mathematics have not been realized. This article describes the development and preliminary field testing of a set of measures designed to screen students in…
