This study is quantitative and includes a non-experimental research design between the constructs of the Full Range Leadership Model and Burnout dimensions. This study examined the relationship between leadership styles and burnout as perceived by the follower while controlling gender, age, tenure, and educational attainment. Participants were…

This research aims to examine the effect of birth month on student achievement as well as social and spiritual development in the classroom. We designed this research as a mixed embedded experimental design, one of the mixed research designs. For the experimental group, first-grade students in a primary school in Aziziye District of Erzurum…

A follow-up of a cluster-randomized trial evaluated the long-term impacts of a scale-up model composed of 10 research-based guidelines grounded in learning trajectories. Two treatment groups received the intervention during the prekindergarten year, and one of these groups received follow-through support in kindergarten and first grade.…

Purpose: We aim to identify the most accurate model for predicting adolescent (Grade 9) reading difficulties (RD) in reading fluency and reading comprehension using 17 kindergarten-age variables. Three models (neural networks, linear, and mixture) were compared based on their accuracy in predicting RD. We also examined whether the same or a…

Purpose: This study examined how cultural factors positively or negatively influenced women's access to the principal role and influenced their leadership experiences. The researchers used Hofstede (2011) six dimensions of national culture as a conceptual framework. The Hofstede (2011) model of national culture consists of six dimensions (6D) that…

Research has shown that a profound place value understanding is crucial for success in learning mathematics. At the same time, a substantial number of students struggles with developing a sustainable place value understanding. In this regard, two aspects of the place value system appear especially relevant: First, the knowledge of the decimal…

Effect sizes in the Cohen's d family are often used in education to compare estimates across studies, measures, and sample sizes. For example, effect sizes are used to compare gains in achievement students make over time, either in pre- and post-treatment studies or in the absence of intervention, such as when estimating achievement gaps. However,…

The association between academic self-concept and achievement is assumed to be reciprocal. Typically, the association is analyzed by variants of the classical cross-lagged panel model. Results with more recently developed methodological approaches, for example, the random intercept cross-lagged panel model, its continuous-time implementation, and…

This study examined achievement trajectories in mathematics and reading from school entry through the end of middle school with linear and nonlinear growth curves in 2 large longitudinal data sets (National Longitudinal Study of Youth--Children and Young Adults and Early Childhood Longitudinal Study--Kindergarten Cohort [ECLS-K]). The S-shaped…

Scaling up educational interventions in the STEM (Science, Technology, Engineering, and Mathematics) field is critical but under-researched. We review and draw implications from a series of studies investigating the long-range impact of an implementation of an early mathematics scale-up model based on learning trajectories. Lasting effectiveness…

This paper aims to demonstrate the importance of controlling for endogenous peer effects in estimating the influence of gender peer effects on educational outcomes. Using Manski's linear-in-means model, this paper illustrates that the estimation of gender peer effects is potentially biased in the presence of endogenous peer effect in education.…

Although the research literature regarding language growth trajectories is burgeoning, the shape and direction of English Language Learners' (ELLs) language growth trajectories are largely not known. This study used growth curve modeling to determine the shape of ELLs' language growth trajectories across 12,248 oral narrative language samples…

Background/Context: Past research has examined many factors that contribute to the black-white achievement gap. While researchers have shown that teacher perceptions of students' academic ability is an important contributing factor to the gap, little research has explored the extent to which teacher perceptions of students' academic ability are…

Comprehensive models of derived polymorphemic word recognition skill in developing readers, with an emphasis on children with reading difficulty (RD), have not been developed. The purpose of the present study was to model individual differences in polymorphemic word recognition ability at the item level among 5th-grade children (N = 173)…

The three-tiered reading model is a widely practiced instructional scheme that moves students in and out of reading intervention groups during the school year. Though designed to treat students who need extra help learning to read, this interruption of reading interventions may hinder some students' progress. The purpose of this study was to…
