The internal validity of observational study is often subject to debate. In this study, we define the counterfactuals as the unobserved sample and intend to quantify its relationship with the null hypothesis statistical testing (NHST). We propose the probability of a robust inference for internal validity, that is, the PIV, as a robustness index…

Developmental dyscalculia (DD) is a specific learning disability in mathematics that affects around 6% of the population. Currently, the core deficit of DD remains unknown. While the number sense deficit hypothesis suggests that the core deficit of DD lies in the inability to represent nonsymbolic numerosity, the access deficit hypothesis suggests…

Saudi Arabia is one of the countries that encounter the issue of bilingualism due to the spread of private schools that offer programs in different languages. This research is an attempt to investigate the impact of bilingualism on the creative capabilities (Fluency, Flexibility, Originality, Details) of kindergarten children in Riyadh. It aims at…

Research Findings: In Study 1, we observed 32 Chinese kindergarteners playing a number board game with their caregivers in dyads. Number board game playing provided important opportunities for kindergarteners and their caregivers to talk about an array of number concepts, but their numeracy-related exchanges rarely went beyond counting. In Study…

This research aims to get acquainted with the effectiveness of the active learning strategy in improving the acoustic awareness skills and understanding what is heard by the basic stage students in Jordan by answering the two following questions: This research has been applied to a sample of 60 students from the basic third grade in Al-Ahnaf Ben…

This study aimed at identifying statistically significant differences in citizenship between Saudi hearing and hearing impaired children. The study sample consisted of (167) hearing and (42) hearing impaired children at public kindergartens in Al-Riyadh city, (82) of whom were males and (127) were female children. Data was collected using…

It was investigated whether task-related body movements yield beneficial effects on children's learning of two-digit numbers and whether these learning effects are affected by mirror-based self-observation of those movements. Participants were 118 first-graders, who were randomly assigned to two movement conditions and two non-movement control…

Acting out behaviors is a hindrance to learning across the country. The school-wide positive behavior support (SWPBS) model is a behaviorally-based systems approach to addressing problem behaviors in our school today. The problem this study is designed to address is the issue that student misbehaviors and disruptions cause a loss of valuable…

The relevance of the research problem is due to applying various training programs in the modern education system which are supposed to increase teaching efficiency. In-depth study of some subjects at schools, lyceums and gymnasiums which starts in the elementary school quite often leads to tension and failures of adaptation process in innovative…

This study used a randomized controlled trial design to investigate the ROOTS curriculum, a 50-lesson kindergarten mathematics intervention. Ten ROOTS-eligible students per classroom (n = 60) were randomly assigned to one of three conditions: a ROOTS five-student group, a ROOTS two-student group, and a no-treatment control group. Two primary…

The focus of this study was connections among 3 aspects of mathematical cognition at 2nd grade: calculations, word problems, and prealgebraic knowledge. We extended the literature, which is dominated by correlational work, by examining whether intervention conducted on calculations or word problems contributes to improved performance in the other…

Research Findings: This study used data from a national sample to examine differences in school outcomes at the end of kindergarten between Head Start children who attended full-day and half-day programs. Propensity scores were used to match children who experienced different intensities of the program on a series of demographic characteristics in…

Understanding of base 10 and place value are important foundational math concepts that are associated with higher use of decomposition strategies and higher accuracy on addition problems (Laski, Ermakova, & Vasilyeva, 2014; Fuson, 1990; Fuson & Briars, 1990; National Research Council, 2001). The current study examined base-10 knowledge,…

This study investigated how gifted children with dyslexia might be able to mask literacy problems and the role of possible compensatory mechanisms. The sample consisted of 121 Dutch primary school children that were divided over four groups (typically developing [TD] children, children with dyslexia, gifted children, gifted children with…

There are so many different intervention programs for educators to use to increase the reading achievement of below grade level students, that it can often be difficult to choose the appropriate one for the students. Most programs are scripted and are used with small groups of students. Reading Recovery is not a scripted program and is taught in a…
