This study elucidates the relationship between instructional leadership and teacher self-efficacy by identifying the moderating role of teacher collegiality. Survey data were collected from 1,498 teachers at 53 middle schools in Henan, China. Findings indicate that instructional leadership has a positive impact on teacher self-efficacy. More…

The present research evaluated whether behavioral tasks ("direct assessments") commonly used to assess young children's social cognitive development in laboratory studies could have utility for measuring and predicting U.S. children's outcomes in educational contexts. To do so, children (N = 95; 49 boys, 46 girls; 41.05% White, 16.84%…

Previous research has found mixed results for a link between executive function and perspective-taking. One proposed reason for this is that perspective-taking during comprehension tasks may not be internally reliable. This dissertation presents two large individual differences experiments with multiple perspective-taking during comprehension and…

Cyberbullying research focuses largely on children and adolescents. Relatively little is known about cyberbullying among adults, particularly their perceived severity and likelihood of intervening in different cyberbullying acts. This research presents two studies that aimed to address these gaps. Utilizing Willard's (2007) classification, study 1…

Nonresponse bias is a widely prevalent problem for data on education. We develop a ten-step exemplar to guide nonresponse bias analysis (NRBA) in cross-sectional studies and apply these steps to the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011. A key step is the construction of indices of nonresponse bias based on proxy…

This study conceptually replicated Huensch and Tracy-Ventura's (2017) analysis of the relationship between L1 and L2 utterance fluency with adult L1-English learners of Spanish. Data from 88 participants were analyzed to explore the proportion of the variance in L2 fluency measures that can be attributed to the corresponding L1 measures, and the…

With the rise in popularity of social media and e-commerce platforms, "discrete math" is at the heart of our online experiences, playing a front-end role in the recommendation of what to click, watch, or buy, or who to follow or friend, as well as a back-end role in data storage, access, and transfer. This thesis focuses on two such…

The article describes a methodology for studying Fresnel diffraction with the active involvement of students in discussing the results of a demonstration experiment. To create a clearly visible model of Fresnel zones, a centimeter radio wave range was chosen, in which the first zone is about 10 cm in size. This makes visible the created…

Objective: Determine whether the ACSM walking equations, which calculate caloric expenditure, were accurate for college-aged males and females. Participants: Between 2011 and 2016, 100 college-aged males, 20.24 ± 2.0 years old, and 100 college-aged females, 20.8 ± 1.3 years old, volunteered to participate. Methods: Participants walked on a…

One of the main current challenges in Educational Data Mining and Learning Analytics is the portability or transferability of predictive models obtained for a particular course so that they can be applied to other different courses. To handle this challenge, one of the foremost problems is the models' excessive dependence on the low-level…

Early Warning Systems (EWS) in higher education accommodate student counsellors by identifying at-risk students and allow them to intervene in a timely manner to prevent student dropout. This study evaluates an EWS that shares student-specific risk information with student counsellors, which was implemented at a large Dutch university. A…

Whether spanking is detrimental for social-emotional (SE) development remains controversial, mostly due to disputes around the internal and external validity of existing evidence. This study examined the effect of spanking on the SE development of Bhutanese children, using a national, longitudinal sample (N = 1377; M[subscript age] = 50.5 months…

Automated Essay Scoring (AES) technologies provide innovative solutions to score the written essays with a much shorter time span and at a fraction of the current cost. Traditionally, AES emphasized the importance of capturing the "coherence" of writing because abundant evidence indicated the connection between coherence and the overall…

Understanding the response process used by test takers when responding to multiple-choice questions (MCQs) is particularly important in evaluating the validity of score interpretations. Previous authors have recommended eye-tracking technology as a useful approach for collecting data on the processes test taker's use to respond to test questions.…

Futures studies offer a framework of ideas and guidelines that allow us to develop more productive images of the future and ways of working with it. Despite several efforts to translate this approach to different educational contexts, it is still a field under development. The main objective of this article is to present and discuss the latest…
