Developing both conceptual and procedural knowledge is important for students' mathematics competence. This study examined whether U.S. Grade 9 general education mathematics teachers' self-reported use of concept-focused instruction (CFI) and procedure-focused instruction (PFI) were associated differently with ninth graders' algebra achievement…

Rate of change (i.e., slope) is a critical mathematics concept for success in everyday life, academics, and professional careers. Students with or at risk of learning disabilities struggle with solving rate-of-change problems, especially word problems. Interventions that incorporate representations and problem-solving strategies are effective for…

Two studies investigated the effects of a live, collaborative Professional Development (PD) program versus individualized PD with a multimedia software program. For both studies, teachers were randomly assigned to either a Virtual Workshop (VW) group that used the software program or to an Actual Workshop (AW) group that participated in a…

This study examined whether there are differences between Israeli students with learning disabilities (LD) and their typically developing peers with regard to their 21st-century skills according to their self-report and whether the differences between the two groups are greater in postsecondary education than in high school--an aim that had not…

The long-term negative consequences of learning difficulties have been acknowledged. Nonetheless, research is still scarce regarding the prediction of adolescent difficulties in reading and arithmetic skills. The present study examines at which age phase and with what kind of constellation of parent- and child-related factors can adolescent…

The current study examined German spelling errors among students with German as their first language (L1) and those with German as their second language (L2) in Grades 3-4 (elementary school students; n = 127) and Grades 5-7 (secondary school students; n = 379). Five hundred and six students participated in the study. We performed two separate…

In this article, I systematically review evidence on the relations between oral reading fluency (ORF) and reading comprehension (RC) for adolescents with limited reading proficiency (ALRP) in Grades 6 to12. I organized findings from 23 studies into five themes: (a) unclear role of ORF in the simple view of reading model for ALRP, (b) ALRP have…

This study analyzed performance, process, and survey data of eighth graders with learning disabilities (LDs) who took the 2017 National Assessment of Educational Progress (NAEP) digital math test. Compared with students with LDs who did not receive extended time accommodations (ETAs), students with LDs who received and used ETA scored…

The purpose of this study was to examine the effects of algebraic equation solving intervention for sixth graders with mathematics learning difficulties (MD). A total of 48 students with MD were randomly assigned to either the algebraic equation solving intervention, "Mystery Math" (n = 24) or control condition (n = 24). The…

Copying a text quickly and accurately is important both in school and in daily life. However, this skill has never been systematically studied, either in children with typical development (TD) or in children with specific learning disabilities (SLD). The aim of this research was to study the features of a copy task and its relationship with other…

The study tested whether cognitive retroactive transfer (CRT) of language skills from English to Hebrew takes place; specifically, whether an improvement in linguistic and meta-linguistic skills in English as a foreign language (FL) would lead to an improvement in these skills in Hebrew as the first language (L1). The participants consisted of 124…

Handwriting difficulties are frequently mentioned in descriptions of developmental coordination disorder (DCD). Recent studies have shown that children with DCD pause more and produce less text than typically developing (TD) peers. This temporal dysfluency indicates a lack of automaticity in handwriting production. One possible contributing factor…

The academic underperformance of high school students with learning disabilities may reduce their access to higher education and decrease their employment opportunities. Based on stereotype threat hypothesis, the present study examined the role of stereotype threat in academic performance among adolescents with learning disabilities and the…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

We examined the efficacy of a content acquisition and reading comprehension intervention implemented in eighth-grade social studies classrooms. Using a within-teacher randomized control design, 18 eighth-grade teachers' social studies classes were randomly assigned to a treatment or comparison condition. Teachers taught all their classes…
