Clarke, Ben; Strand Cary, Mari G.; Shanley, Lina; Sutherland, Marah – Assessment for Effective Intervention, 2020
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…

Doabler, Christian T.; Clarke, Ben; Kosty, Derek B.; Baker, Scott K.; Smolkowski, Keith; Fien, Hank – School Psychology Review, 2016
There is a dearth of research on Tier 1 instruction designed to improve the mathematics achievement of English learners. This study examined the impact of a core kindergarten mathematics curriculum on the mathematics achievement of Spanish-speaking English learners (SS-ELs). Secondary aims tested for differential response to the curriculum among…

Clarke, Ben; Smolkowski, Keith; Baker, Scott K.; Fien, Hank; Doabler, Christian T.; Chard, David J. – Elementary School Journal, 2011
This study examined the efficacy of a core kindergarten mathematics program, ELM, a 120-lesson comprehensive curriculum providing instruction in (a) number operations, (b) geometry, (c) measurement, and (d) vocabulary. ELM is designed to address the learning needs of all students, including at-risk students in the general education or Tier I…

Lesner, Taylor; Clarke, Ben; Kosty, Derek; Nelson, Nancy; Ketterlin-Geller, Leanne; Smolkowski, Keith – Learning Disability Quarterly, 2023
This study explored whether initial skill moderated outcomes of Promoting Algebra Readiness, a Tier 2 sixth-grade mathematics intervention targeting conceptual and procedural knowledge of fractions. The study analyzed data from a quasi-experimental pilot study in which at-risk students (N = 198) from Oregon middle schools were assigned to the…

Doabler, Christian T.; Clarke, Ben; Kosty, Derek; Maddox, Steven A.; Smolkowski, Keith; Fien, Hank; Baker, Scott K.; Kimmel, Georgia L. – Grantee Submission, 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 severe MD at kindergarten entry and examined whether these students improved…

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…
