Existing research practices in gifted education have many areas for potential improvement so that they can provide useful, generalizable evidence to various stakeholders. In this article, we first review the field's current research practices and consider the quality and utility of its research findings. Next, we discuss how open science practices…

Partial least squares structural equation modeling (PLS-SEM) has become a key multivariate statistical modeling technique that educational researchers frequently use. This paper reviews the uses of PLS-SEM in 16 major e-learning journals, and provides guidelines for improving the use of PLS-SEM as well as recommendations for future applications in…

Current events have highlighted ethical lapses and disregard for corporate social responsibility (CSR) in companies. Scandals at Volkswagen, Wells Fargo, and Turing Pharmaceuticals, as well as the 2008 mortgage crisis demonstrate the need for ethics training and CSR. Human resource development (HRD) strategies and initiatives can aid companies in…

Cognitive diagnosis models (CDMs) have gained increasing popularity recently because of their potential to provide diagnostic inferences that can inform learning and teaching. However, the development of cognitive diagnostic assessments (CDAs) is lagging behind the development of the associated psychometric models. At present, it is not clear…

The literature suggests that simple expert (mathematical) models can improve the quality of decisions, but people are not always eager to accept and endorse such models. We ran three online experiments to test the receptiveness to advice from computerized expert models. Middle- and high-school teachers (N = 435) evaluated student profiles that…

Computer programming and mathematical algorithms are natural partners in the development of programming skills, logical thought, and a deeper understanding of mathematical concepts. We present the details of a course which blends the two at the sophomore level. This course is required of our mathematics majors, but attracts mathematics minors from…

Arithmetic problem solving is a crucial part of mathematics education. However, existing problem solving theories do not fully account for the semantic constraints partaking in the encoding and recoding of arithmetic word problems. In this respect, the limitations of the main existing models in the literature are discussed. We then introduce the…

The purpose of this grounded theory study was to develop a model of biblical worldview development for Evangelical Christians during emerging adulthood. Data were collected via personal worldview development timelines, semi-structured interviews, and a focus group. The study provided insight into a maturing biblical worldview, including growth in…

Visual word recognition is facilitated by the presence of "orthographic neighbors" that mismatch the target word by a single letter substitution. However, researchers typically do not consider "where" neighbors mismatch the target. In light of evidence that some letter positions are more informative than others, we investigate…

This article describes a research-based and developmentally informed model of reflective practice for mentoring in the context of leadership development. The event path model of professional reflection helps individuals and organizations move to a more postindustrial model of leadership, improving the self-efficacy and agency of those involved.

A nonconverged Markov chain can potentially lead to invalid inferences about model parameters. The purpose of this study was to assess the effect of a nonconverged Markov chain on the estimation of parameters for mixture item response theory models using a Markov chain Monte Carlo algorithm. A simulation study was conducted to investigate the…

This paper focuses on MOOCs (massive open online courses), a fairly recent paradigm in e-learning educational projects. Despite the high dropout rate, and the impossibility of benefiting from the opportunities that bring with it a face-to-face dialogue, several factors make MOOCs a good option for ongoing teacher professional learning. The MOOCs…

This study aims to conduct differential item functioning analyses in the context of cognitive diagnosis assessments using various formulations of the Wald test. In implementing the Wald test, two scenarios are considered: one where the underlying reduced model can be assumed; and another where a saturated CDM is used. Illustration of the different…

The Education Value-Added Assessment System (EVAAS), the value-added model (VAM) sold by the international business analytics software company SAS Institute Inc., is advertised as offering "precise, reliable and unbiased results that go far beyond what other simplistic [value-added] models found in the market today can provide." In this…

This article draws on the ecological model of teacher agency and elaborates on how teacher agency is achieved, its components and how it could be strengthened. This model highlights professional competence, structural and cultural context, and professional purpose as the main elements of achieving agency. In this paper, we specify some elements of…
