Early childhood mathematics education takes attention for decades. The effect of qualified mathematics education during early years has an impact on children's future academic success. Main purposes of the study were twofold; to examine children's current 3D geometry thinking skills and to investigate the development of children's 3D geometry…

Some students with gifts and talents (SWGT) are among the thousands of youths who die by suicide every year, although there is no way to know how many. Research indicates they are not more likely to engage in suicidal behaviors than other students. They do have unique risk and protective factors, however. Risk factors can accumulate to outweigh…

Purpose: The purpose of the current study was to examine the effects of code-switching on bilingual children's online processing and offline comprehension of sentences in the presence of noise. In addition, the study examined individual differences in language ability and cognitive control skills as moderators of children's ability to process…

Augmentative and Alternative Communication (AAC) is a core component of special education for many children with learning disabilities and/or autism who have minimal or no speech. Much literature focuses on implementation of AAC in the classroom or therapy setting, but less is known about how AAC is used in the family home. Few studies are…

In cognitive diagnostic modeling research, one area that has not had enough research interests is remedial learning or instruction based on the information provided by cognitive diagnostic assessment (CDA). The present study tries to address this research gap by looking into the usefulness of the fine-grained score reports based on CDA in two…

Studies of switching between tasks and studies of error commission have both provided solid behavioral measures of executive control. Nonetheless, a gap remains between these strands of research. In three experiments we sought to reduce this gap by assessing the impact of task errors on N-2 repetition costs, an effect supposedly related to…

This study was an attempt to find out the impact of Montessori teaching method on EFL learners' writing achievement. To fulfill the purpose of the study, out of 150 students, 95 male and female students were selected randomly to participate in this study. All of them were given a pretest to find out their level of proficiency. They had no…

Evidence for the role of procedural memory in second language (L2) acquisition has emerged in our field. However, little is known about the reliability and validity of the procedural memory measures used in this research. The present study (N = 119) examined the reliability and the convergent and discriminant validity of three assessments that…

Research on elementary students' reasoning on patterning problems with pictorial representations has illustrated that students can visualize structure in patterns in different ways. In this paper, we offer a characterization of students' spatial structures and numerical structures and explain how the link between these two structures can support…

Background and aims: Prior work has examined how children and adolescents with autism spectrum disorder who are minimally verbal use their spoken language abilities during interactions with others. However, social communication includes other aspects beyond speech. To our knowledge, no studies have examined how minimally verbal children and…

This article focuses on the unintended consequences of within-class ability grouping on primary students of mathematics. I review relevant research, including promising approaches to teaching in mixed ability settings. I then outline four ways in which these groupings are typically structured, discussing some of the issues that arise with each of…

The purpose of this study is to explore the statistical nature of the linguistic interdependence hypothesis (Cummins, 1976, 2017) in the spring of 2nd grade of students in foreign language immersion programs. Specifically, the interdependent relationship between L2 language proficiency levels and L1 reading academic performance in an environment…

Prior research has found gender differences in spatial tasks in which men perform better, and are more confident, than women. Do gender differences also occur in people's confidence as they perform number-line estimation, a common spatial-numeric task predictive of math achievement? To investigate this question, we analyzed outcomes from six…

This study examined the association between observed cognitive sensitivity (CS) during family interactions and children's receptive vocabulary for older and younger siblings. Maternal and sibling CS was considered and associations were explored at the family-wide (between-family) and child-specific (within-family) levels of analysis. The…
