Parnika Bhatia; Jessica Léone; Marie-Line Gardes; Jérôme Prado – Learning Disability Quarterly, 2024
Fractions are challenging for both typically achieving children and adults. Although some prior research has focused on fraction difficulties of children with mathematics difficulties (MD), persistent difficulties encountered by adults with MD remain unknown. It is possible that these adults may be able to compensate for some deficits. In this…

Megan Rojo; Sarah G. King; Jenna Gersib; Christian T. Doabler – Learning Disability Quarterly, 2025
Competence with rational numbers is essential for mathematics proficiency in secondary mathematics. However, many students struggle with rational number concepts, and students with mathematics difficulties struggle even more. The purpose of this study was to examine the effects of an intervention that incorporated the use of explicit instruction…

Jessica H. Hunt; Kristi Martin – Learning Disability Quarterly, 2024
Productive engagement in fractional reasoning is essential for abstracting fundamental algebraic concepts vital to college and career success. Yet, data suggest students with learning disabilities (LDs), in particular, display pervasive shortfalls in learning and mastering fraction content. We argue that shortfalls in understanding are in fact…

Margaret M. Flores; Vanessa M. Hinton; Kelly B. Schweck – Learning Disability Quarterly, 2024
The purpose of this study was to investigate the effects of the concrete-representational-abstract--integrated (CRA-I) sequence on students with learning disabilities' performance when learning fraction and decimal concepts. Three elementary-level students in Grades 4 and 6 participated in a single-case multiple probe across behaviors study. The…

Taylor Lesner; Ben Clarke; Derek Kosty; Nancy Nelson; Leanne Ketterlin-Geller; Keith Smolkowski – 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…

Hunt, Jessica H.; Martin, Kristi; Khounmeuang, Andy; Silva, Juanita; Patterson, Blain; Welch-Ptak, Jasmine – Learning Disability Quarterly, 2023
One of the most persistent areas of difficulty in mathematics for children with learning disabilities (LDs) and difficulties is fractions. We report the development and initial testing of an intervention designed to increase access to and advancement in conceptual understanding. Our asset-based theory of change--a tested and confirmed learning…

Ben Clarke; Nancy J. Nelson; Leanne Ketterlin Geller; Derek Kosty; Keith Smolkowski; Taylor Lesner; David Furjanic; Hank Fien – Learning Disability Quarterly, 2022
This pilot study examined the promise of a Tier 2 Grade 6 intervention program for students at risk for difficulties in mathematics. The study utilized a quasi-experimental design. The final sample included 112 students in treatment (Promoting Algebra Readiness) and 86 students in control (standard district practice) conditions. The Promoting…
