The National Council of Teachers of Mathematics (NCTM) emphasizes the teaching of "Big Ideas" in mathematics. This study focuses on the part-part-whole (PPW) relationship as a crucial aspect of word problem solving involving addition and subtraction. This study, conducted in the United States, evaluated the effects of conceptual…

Reading comprehension is a fundamental skill to be developed from the early stages of reading acquisition and it is essential for both formative and personal learning. This study examines eye-tracking as a useful and complementary tool in the assessment and improvement of implicit reading comprehension. The aim is to understand the role of…

While symbolic number processing is an important correlate for typical and low mathematics achievement, it remains to be determined whether children with high mathematics achievement also have excellent symbolic number processing abilities. We investigated this question in 64 children (aged 8 to 10), i.e., 32 children with persistent high…

The present study aimed to investigate the effects of the EASY Minds program on working memory and selective attention of a group of Iranian students with maths learning disabilities. The study had a quasi-experimental research design with pre-test, post-test, and follow-up tests. Forty students with maths learning disabilities were randomly…

This quasi-experimental study examined the impact of reading aloud using theme-based material on the change from baseline to study endpoint in Crystallized Intelligence (Gc) of first grade students (Kaufman & Kaufman, 2004). A total of 39 students (19 male, 20 female) from two districts in a Midwestern state were recruited to participate. To…

We examined the associations of cognitive skills, math-related emotions and beliefs, and gender with responses to an arithmetic fluency intervention. Elementary school children with dysfluent arithmetic skills (N=69) participated in an arithmetic fluency intervention (with and without self-efficacy support) implemented in small groups in schools…

Morphemes, the smallest meaning-bearing units of language, recur in many words. Therefore, morphological knowledge can facilitate the comprehension of novel words. This study tested the effectiveness of a morphological training program on children's learning and retention of exposed words and morphologically related unexposed words compared with…

Introduction: Existing studies of the variables that can impact reading comprehension at intermediate levels of Primary Education are not entirely conclusive. The present study analyzes the contribution to reading comprehension made by domain-general skills, such as fluid intelligence (Gf) and working memory (WM), and domain-specific skills, such…

The phonological loop of the working memory system plays a key role in language learning. This study examined the trajectories between two dual-language learner groups (English Learners [ELs] and Spanish Learners [SLs]) on phonological loop measures in L1 and L2. At Grade 1, children completed a battery of vocabulary and cognitive measures and…

This study examines the relationship between perceived stress, nonverbal cognitive functioning, and statewide academic scores in both Latinx and European American elementary students in rural school districts. A total of 44 third graders participated in the study, including 13 Latinx students and 31 European American (EA) students. Perceived…

This study's purpose was to investigate effects of 3 intervention approaches for building working memory (WM) and improving word-problem solving (WPS). Children with mathematics difficulties (n = 240; 7.51 years [SD = 0.33]) were randomized to 4 conditions: a control group, general WM training with contiguous math practice, WPS intervention…

Students with and at-risk for academic and behavioral challenges often have low levels of academic engagement. Providing instructional choice is one way to increase engagement in the classroom. In this study, we replicated and extended previous inquiry by investigating the effects of across-activity choices offered by third-grade teachers during…

This project tested the effects of adding instruction of trios of children in patterning, mathematics, early literacy, or social studies to ongoing instruction in kindergartens. Children were randomly assigned to trios which were randomly assigned to one of four kinds of instruction. A quarter of the trios received patterning instruction with a…

Learning to compose texts adequate for different purposes is crucial for becoming literate. We examined developmental changes in the rhetorical structure of written texts produced by Spanish children throughout the early years of elementary school in the light of descriptive writing purposes. Children had also performed tasks to test…
