Purpose: This study aims at investigating the phonological development of the six guttural consonants of Jordanian Arabic, /[chi]/, /[voiced uvular fricative]/, /[voiceless pharyngeal fricative]/, /[voiced pharyngeal fricative]/, /[glottal stop]/, and /h/. Method: An articulation test is designed to involve two tasks: picture naming and…

The component structure of executive functioning (EF) has been shown to change across development. Empirical research examining this in Sub-Saharan Africa is limited. We report the development of EF component structure with a large sample of Ghanaian children (n = 2,979) followed longitudinally from ages 3 through 12 across six waves. Existing…

Functional magnetic resonance imaging (fMRI) studies with adults provide evidence that functional brain networks, including the default mode network and frontoparietal network, underlie executive functioning (EF). However, given the challenges of using fMRI with infants and young children, little work has assessed the developmental trajectories of…

Like many Montessori educators, the author was immediately drawn to the materials Maria Montessori designed for children in the conscious absorbent mind. They are simple, beautiful, and attractive to children. To many, including some parents, these materials are the essence of Montessori. However, Maria Montessori herself thought of her Method as…

Objective: To examine the role of executive functioning (EF) in health self-management and the transition to adult health care among college students. Participants: A total of 378 undergraduate students from a public university participated in the study. Methods: Participants reported on EF, health self-management skills, and their readiness to…

This article describes how intra- and interdisciplinary learning experiences can activate the interests and capabilities among children in their early years. A developmental sequence delineates a series of stage-by-stage experiences describing the skill and content to be introduced and mastered in the teaching and learning process, which include…

The exploration and/or manipulation of objects and materials, referred to as object-oriented play (OOP), is one of the most prominent activities children engage in during early childhood. Especially within early childhood education, it is important to be able to assess and understand OOP, its developmental trajectory, and developmental value. This…

Background: Computational thinking (CT) has emerged as a critical component of 21st-century skills, and increasing effort was seen in exploring the development of CT skills in K-12 students. Despite cumulative research on exploring students' CT acquisition and its influencing factors, learners' development of the skill over time and the underlying…

By 12 months of age, infants exhibit behavioral sensitivity to sound symbolism (e.g. sound-shape correspondences) when they hear universally sound symbolic pseudowords (e.g. "bouba," "kiki"). Here, we investigated whether infant's sensitivity to sound-shape correspondences is affected when they hear language-specific sound…

This longitudinal study tested the notion of a hierarchy of maths skill development by examining whether the development of later acquired arithmetic skills rely on development of earlier acquired arithmetic skills. The scores of 307 children on single-digit arithmetic, multi-digit calculation, arithmetic word problem-solving, and reading…

A basic question about bilingual development is how the acquisition of one language affects the acquisition of the other. Previous findings are few and mixed. The present study addressed this question with longitudinal data on the dual-language vocabulary growth of 149 US-born children from Spanish-speaking immigrant families, who were followed…

Emotions hover like a shadow over the lives and work of school principals. This study aimed to build an understanding of principals' emotional trajectories across principalship career stages by investigating the life stories of four excellent principals from China who were approaching retirement. The major data source was semi-structured…

Defining developmental progressions can be an important step in identifying developmental precursors and mechanisms of change, within and across areas of reasoning. In one exploratory study, we examine whether the development of children's thinking about ownership follows a systematic progression wherein some components emerge reliably before…

Mental health and well-being among high-performing male and female engineering students were investigated to account for variance. A self-report survey was used to assess mental health and well-being, and the results of the end-of-year evaluation were used to measure academic accomplishment. This study was unique in that it created the…

This dissertation investigates the effectiveness of a professional development program aimed at enhancing early childhood education (ECE) teachers' abilities to identify and address developmentally appropriate versus maladaptive behaviors in young children. Utilizing an explanatory sequential mixed methods design, the study involves pre- and…
