Even though online teaching and learning in the LIS field is not new, in-depth research efforts specifically addressing the relationship between social presence and its value to the success of online collaborative learning (OCL) for students in Master of Library and Information Science (MLIS) programs in the United States has seldom been…

Dynamic biochemical processes are often difficult for students to grasp in the classroom using static images or models, or even through watching simulation videos. This is particularly true for protein-folding and enzyme catalysis, two key biochemistry concepts. The author has developed and tested two 3D, dynamic, and interactive classroom models,…

Students in our nation's largest school systems--a majority of whom are students of color from nondominant communities--are unlikely to attend schools with strong, consistent leadership. Those big-city school systems are increasingly adopting principal pipeline initiatives to address the quality and stability of their principal corps. Principal…

The literature is sparse for studies on the leadership behaviors of engineers. Traditionally, organizations generally view engineers as problem-solvers, and their career advancement is more often along a technical track rather than a leadership track. Because today's organizations are seeking employees who can think creatively in order to find…

In the Spring of 2019, the Center for Education Policy Research at Harvard University launched the National Center for Rural Education Research Networks (NCRERN) with funding from the U.S. Department of Education's Institute of Education Sciences. This overview provides a step-by- step description of NCRERN's continuous improvement model. NCRERN's…

A growing literature uses value-added (VA) models to quantify principals' contributions to improving student outcomes. Principal VA is typically estimated using a connected networks model that includes both principal and school fixed effects (FE) to isolate principal effectiveness from fixed school factors that principals cannot control. While…

The deviance information criterion (DIC) is widely used to select the parsimonious, well-fitting model. We examined how priors impact model complexity (pD) and the DIC for Bayesian CFA. Study 1 compared the empirical distributions of pD and DIC under multivariate (i.e., inverse Wishart) and separation strategy (SS) priors. The former treats the…

Structural equation modeling (SEM) is being applied to ever more complex data types and questions, often requiring extensions such as regularization or novel fitting functions. To extend SEM, researchers currently need to completely reformulate SEM and its optimization algorithm -- a challenging and time-consuming task. In this paper, we introduce…

The main purpose of this work is to substantiate the essential and semantic, structural and content, and functional understanding and explanation of the paradigm and the paradigm shift in education; also, to identify the deterministic foundations of the paradigmatic shift, the parameters of its manifestation, and the potential of riskiness in…

In secure web application development, the role of web services will not continue if it is not trustworthy. Retaining customers with applications is one of the major challenges if the services are not reliable and trustworthy. This article proposes a trust evaluation and decision model where the authors have defined indirect attribute, trust,…

Increasingly, Ed.D. programs are challenged to produce graduates with the skills and expertise needed to create and foster change in the various educational environments in which they serve. Promoting, and more importantly, preparing the Ed.D. Activist is a theme that was addressed during the October 2019 convening of the Carnegie Project on the…

Modern societies, new technical equipment and technology confirm the importance of knowledge acquisition in everyday life, especially in economy. An education system is a non-profit system. Since it strongly affects economic efficiency, its quantification becomes a very complex process. In order to make the quantification process possible, this…

In the literature, estimation results of the determinants of academic achievement are controversial. There may be several reasons for these controversial results, including sample or cultural differences. Conversely, these results may arise from ignoring certain important facts, such as an interaction effect. Some studies do not consider…

The use of smart devices as media for digital learning constitutes a new-generation digital learning paradigm. Therefore, context-aware game-based learning has attracted considerable attention. Location-based games have not only positive effects on learning but also pronounced effects on culture and history. Accordingly, focusing on railway…

Previous research suggests that preschoolers struggle with understanding abstract relations and with "reasoning by analogy." Four experiments find, in contrast, that 3- and 4-year-olds (N = 168) are surprisingly adept at relational and analogical reasoning within a causal context. In earlier studies preschoolers routinely favored images…
