First graders with Developmental Language Disorder are considered at risk for exhibiting Specific Learning Disorder during school years. They also have deficiencies in their metacognitive skills, which leads to less effective learning processes. The current study examined, for the first time, the added value of various types of metacognitive…

This study investigated the stability of latent classes of students with learning disabilities among a heterogeneous sample of elementary-aged children whose first language is Spanish. To this end, children (N = 284) in Grades 1, 2, and 3 at Wave 1 (Year 1) were administered a battery of vocabulary, reading, math, and cognitive measures…

This study replicates and extends prior research on multisensory mathematics instruction (Grünke, Urton, & Karnes, 2018) by integrating a touch points strategy, performance feedback, reward system, and a reinforcing card game into an instructional package. A multiple baseline design across participants was used to evaluate the effects of the…

Achieving proficiency in core foundational oral language (OL), reading, and writing skills remains difficult for students with specific learning disabilities (SLD) and foundational OL difficulty (National Center for Educational Statistics, 2022). Despite evidence linking OL skills in grammar (morphosyntax, syntax) and vocabulary (semantics) to…

We examined dynamic assessment's (DA's) added value over traditional assessments for identifying Spanish-speaking English learners' (ELs) risk for developing mathematics disabilities, as a function of the language of test administration (English vs. Spanish), type of math outcome, and EL's language dominance. At the start of first grade, ELs (N =…

We examined longitudinal relations between 1st-grade cognitive predictors (early nonverbal reasoning, processing speed, listening comprehension, working memory, calculation skill, word-problem solving, word-reading fluency, attentive behavior, and numerical cognition) and 2nd-grade academic outcomes (calculations, word-problem solving, and word…

Mathematical difficulties have been distinguished as mathematics learning disability (MLD) and persistent low achievement (LA). Based on 1,880 Finnish children who were followed from kindergarten (age 6) to fourth grade, this study examined the early risk factors for MLD and LA. Distinct groups of MLD (6.0% of the sample) and LA (25.7%) children…

This paper reviews findings from four research syntheses that report the effects of academic language and/or reading interventions on language and reading outcomes for English learners who have or are at risk for learning difficulties. Studies included in the syntheses varied in research design and addressed multiple areas of reading and language.…

We examined dynamic assessment's (DA's) added value over traditional assessments for identifying Spanish-speaking English learners' (ELs') risk for developing mathematics disabilities, as a function of the language of test administration (English vs. Spanish), type of math outcome, and EL's language dominance. At the start of 1st grade, ELs (N =…

This study investigated the prevalence and stability of latent classes among elementary-aged English learning (EL) children whose first language is Spanish. To this end, EL children (N = 267) in Grades 1, 2, and 3 at Wave 1 (Year 1) were administered a battery of vocabulary, reading, math, and cognitive measures (short-term memory, working memory,…

In this synthesis, we reviewed 65 studies involving elementary students (i.e., grades 1-5) identified with mathematics difficulty (MD) in which authors implemented a mathematics intervention. Of these studies, we identified 33 group designs, 9 quasi-experimental designs, and 23 single-case designs. We aimed to synthesize performance differences…

The first purpose of this study was to examine the prevalence of risk for comorbid reading and mathematics disabilities (RMD) at start of first grade, when measured in a representative sample of 3,062 students with first-grade fluency measures (word reading; computation). The second purpose was to examine the utility of these measures for…

Self-efficacious children are expected to be more task-focused in challenging achievement situations and consequently have better chances of overcoming learning difficulties than children who have lower self-efficacy. The present study investigates this presumption with Finnish-speaking first graders struggling with reading acquisition (N = 285).…

A meta-analysis of single-case design research was conducted to evaluate the effectiveness of mathematics interventions for elementary grade (K-5) students with mathematics difficulties (MD) and mathematics learning disabilities (LD). The study examined whether intervention effectiveness varied as a function of participant characteristics (i.e.,…

This study aimed to study the association between diglossic reading skills and reading comprehension in first grade students with and without learning disabilities. In this study population, students presented diglossia in literary and colloquial Arabic: 30 first grade students with learning disabilities and 30 first grade students without…
