"How do witnesses make identification decisions when viewing a lineup?" Understanding the witness decision-making process is essential for researchers to develop methods that can reduce mistaken identifications and improve lineup practices. Yet, the inclusion of fillers has posed a pivotal challenge to this task because the traditional…

Research on inclusive education has gained major importance over the last decade. However, in the English-speaking discourse, empirical studies on inclusive teaching and learning often lack connections to existing educational theories that focus on the interrelation of teachers, learners and content as the three focal points of teaching and…

Several variants of the autoregressive structural equation model were suggested over the past years, including, for example, the random intercept autoregressive panel model, the latent curve model with structured residuals, and the STARTS model. The present work shows how to place these models into a mixed-effects model framework and how to…

Penalized structural equation models (PSEM) is a new powerful estimation technique that can be used to tackle a variety of difficult structural estimation problems that can not be handled with previously developed methods. In this paper we describe the PSEM framework and illustrate the quality of the method with simulation studies.…

Over the past few decades, as the number of extraordinary achievements by research teams and science and technology companies has increased, the power behind the justification of only individual-dimension giftedness theories has decreased. This conceptual paper reveals the organizational dimension of giftedness in the background of scientific and…

Currently, dynamic structural equation modeling (DSEM) and residual DSEM (RDSEM) are commonly used in testing intensive longitudinal data (ILD). Researchers are interested in ILD mediation models, but their analyses are challenging. The present paper mathematically derived, empirically compared, and step-by-step demonstrated three types (i.e.,…

Research on computing in higher education research has been dominated by studies on "things that work" (or not). While useful, the field now needs more research on authentic tech-related problems of practice and viable solutions that resolve them. This article describes one such approach: Educational Design Research (EDR). It begins with…

Unlike previous studies on fixed logistics nodes, this research explored how consumer distribution impacts store selection and inventory balance, integrating the "ship-from-store" strategy to increase fulfillment within multiperiod sales plans. Specifically, omnichannel retailers (O-tailer) must sequentially decide on inventory…

This article focuses on describing a systematic model for constructing, describing, and interpreting logarithmic diagrams as a graphical method for representing redox chemical equilibria. This model considers concepts such as electron potential (p[subscript e]), the chemical equilibrium constant (K[subscript d]), and the standard reduction…

Researchers concerned about intergenerational inequalities study "absolute" and "relative" mobility (e.g., whether people's adult incomes exceed their parents' incomes in "dollars" or "ranks"). Absolute and relative mobility are connected, by definition. Yet, they are not equivalent. Indeed, they often…

We review common situations in Bayesian latent variable models where the prior distribution that a researcher specifies differs from the prior distribution used during estimation. These situations can arise from the positive definite requirement on correlation matrices, from sign indeterminacy of factor loadings, and from order constraints on…

With the goal of moving toward an alternative rate model for child care subsidies, the North Carolina Division of Child Development and Early Education (DCDEE) partnered with the American Institutes for Research® (AIR®) to conduct a study to estimate the true cost of high-quality child care and to recommend three new rate models for the state to…

Background: Training the memorization of declarative knowledge requires the repetitive presentation of various forms of factual questions to learners. Educational games designed for this purpose should offer activities that are both tailored to individual learners and varied to prevent boredom. Whilst the Technology-Enhanced Learning (TEL)…

Discrete time models, one linear and one non-linear, are investigated, both with a herbivore species that consumes a basal food source species. Results are presented for coexistence of the species and to illustrate chaotic behaviour as parameters are varied in the non-linear model. The results indicate the benefit of fertilization in terms of the…

As learning analytics use grows across U.S. colleges and universities, so does the need to discuss the plans, purposes, and paths for the data collected via learning analytics. More specifically, students, faculty, and others who are impacted by learning analytics use should have more information about their campus' learning analytics practices…
